Summary:
As spicyj mentioned in commit 6a838a4, the ideal state of affairs when it comes to consuming `react` and `fbjs` from NPM is for the packager not to have knowledge of either package. This PR addresses the `fbjs` part of that, and relies on https://github.com/facebook/fbjs/pull/95. **DO NOT MERGE** until #95 (or a variation) is in `fbjs` and is released to npm.
This PR does several things:
1. Adds stub modules within RN that expose `fbjs` modules to be required using Haste. After discussing a few ideas with spicyj, this seemed like a good option to keep internal FB devs happy (and not make them change the way they write JS), but allow for removing packager complexity and fit in better with the NPM ecosystem. Note -- it skips stubbing `fetch`, `ExecutionEnvironment`, and `ErrorUtils`, due to the fact that these need to have Native specific implementations, and there's no reason for those implementations to exist in `fbjs`.
2. Removes the modules that were previously being used in lieu of their `fbjs` eq

Summary:

The packager currently assumes that all assets that are not JSON or JS files must be images. Although it is possible to add other extension types, they crash the packager if you try to require them, because it attempts to get their dimensions, assuming that they are an image.
This is a crude workaround for that problem, which skips the image-specific processing for non-image assets, but really it would be better if the packager was properly aware of different asset types and treated them differently (e.g. for sounds it could include the duration, for HTML pages it could parse and include linked CSS files, etc).
I've also added an example of using `require('...')` to load a packager-managed HTML page in the UIExplorer WebView example. In future I anticipate that all static asset types (sounds, fonts, etc.) could be handled in this way, which allows them to be edited or added/removed on the fly instead of needing to restart the app.

Summary:
Rather than specifying Babel plugins in the `.babelrc` packaged with react-native, leverage a Babel preset to define the plugins (https://github.com/exponentjs/babel-preset-react-native).
This allows for a much better user experience for those who want (or need) to override options in their project's `.babelrc`.
Prior to this PR, if a user wanted to use a custom babel-plugin (or a custom set of babel plugins), they'd have either 1) manually override the `.babelrc` in the react-packager directory (or fork RN), or 2) specify a custom transformer to use when running the packager that loaded their own `.babelrc`. Note - the custom transformer was necessary because without it, RN's `.babelrc` options would supersede the options defined in the project's `.babelrc`...potentially causing issues with plugin ordering.
This PR makes the transformer check for the existence of a project-level `.babelrc`, and if it it's there, it _doesn't_ use the react-native `.babelrc`. This prevents any oddities with Babel plug

Right now, a mock called `debug.js` shadows a node module called `debug`. When I made mocking more strict I didn't realize that it didn't include those mocks any more because requiring `debug` would result in a module like `debug/node.js` which doesn't have a mock associated with it. This diff changes it so it looks at the associated `package.json` to match the name up to mocks. This is the least invasive non-breaking change I can make right now. Yes, mocking strategies are basically fucked but I don't want the haste2 integration to have even more breaking changes right now. Consider this code to be temporary, I'll fix this and make the mocking system more sane mid-term.

Summary:
The feature added in D2862850 only adds the module that requests shallow dependency resolution to the dependencies of a module. The reason why this is happens is because `collect` calls `response.addDependency` but if `recursive` is set to `false`, dependencies don't call `collect` and therefore don't get added to the resolution response. This fixes it by adding dependencies outside of the `collect` call.

The FS as seen by an instance of a dependency graph is useful for clients of node-haste. This provides an accessor to fastfs so that the partial view of the filesystem can be queried. I was thinking of splitting out the fastfs creation to outside the constructor but the necessary refactoring doesn't seem worth it. The fastfs is intrinsically tied to the dependency graph and the `DependencyGraph` instance is meant to be a base-class for clients anyway. Both in react-packager and jest we are wrapping it with higher-level client specific containers, Resolver and HasteResolver respectively.

The reason why HMR was originally on the internal transform was so that it worked with non JS code (TypeScript, Coffeescript, etc), but looks like this is not very popupar in the community, maybe because the JS ecosystem is getting better everyday.
So long story short, for now lets move HMR to the external transformer. This should also give us a perf boost.

To make sourcemaps work on Hot Loading work, we'll need to be able to serve them for each module that is dynamically replaced. To do so we introduced a new parameter to the bundler, namely `entryModuleOnly` to decide whether or not to process the full dependency tree or just the module associated to the entry file. Also we need to add `//sourceMappingURL` to the HMR updates so that in case of an error the runtime retrieves the sourcemaps for the file on which an error occurred from the server.
Finally, we need to refactor a bit how we load the HMR updates into JSC. Unfortunately, if the code is eval'ed when an error is thrown, the line and column number are missing. This is a bug/missing feature in JSC. To walkaround the issue we need to eval the code on native. This adds a bit of complexity to HMR as for both platforms we'll have to have a thin module to inject code but I don't see any other alternative. when debugging this is not needed as Chrome supports sourceMappingURLs on eval'ed code

Since the combination of node and haste modules (and modules that can be required as both node and haste module) can lead to situations where it’s impossible to decide an unambiguous module identifier, this diff switches all module ids to integers. Each integer maps to an absolute path to a JS file on disk.
We also had a problem, where haste modules outside and inside node_modules could end up with the same module identifier.
This problem has not manifested yet, because the last definition of a module wins. It becomes a problem when writing file-based unbundle modules to disk: the same file might be written to concurrently, leading to invalid code.
Using indexed modules will also help indexed file unbundles, as we can encode module IDs as integers rather than scanning string IDs.

At the moment we have to disable strict mode for the transform-es2015-modules-commonjs because strict mode leaks to the global scope and breaks the bridge. It was due to the way the polyfills were bundled in the package. To fix it, I wrapped the polyfill modules in an IIFE. Then when strict mode was enabled some polyfills were broken due to strict mode errors so that was fixed too. Also removed the IIFE from the polyfills that included one.
This diff doesn't enable the strict mode transform since some internal facebook modules depend on it not being enabled. When #5214 lands we could make the default babel config shipped with OSS react-native use strict mode modules and facebook could just modify the babel config to disable it if needed.

We used to only cache the `dependencies` and `name` of a Module but we were actually accessing two more fields (async dependencies and the `isHaste` field) which meant we were always reading every single file from disk. In D2644383 I noticed that but realized that the Promise was cached, meaning we would read every file once *per instance* and I didn't think about cross-instance reads over time. My initial version added more caching (but also missed the `isHaste` field) but then I got rid of the cache call for `dependencies`. So my change from before didn't make anything worse but it also didn't make anything better. This change now caches everything until the contents of the file actually changes.

Summary:
One consequence we didn't predict after introducing the Internal Transform Pipeline, was that when the workers would get started, we won't require the external transformer the user specified up until the first time each worker received a job. There're 2 visible consequences of this: (1) the transform progress bar seems to get stuck for about 5 seconds the first time the packager receives a request and (2) the first N (# of cores) HMR requests take way longer (about 4 seconds with FB's transformer instead of << 1 second) as we need to require lots of modules.
This diff creates a temporary file for the js transformer workers that requires the user-specified transform file eagerly.
That makes sure workers have imported babel and the transforms before receiving the first request.
There are better ways to do this, like adding an `init()` method to the workers and call that eagerly. I will follow with another diff doing that.

* env.js didn't properly set up ErrorUtils, also unsure why that isn't a problem in jest right now already?
* some things were mocking things they shouldn't
* Because of the regex that matches against providesModule and System.import, it isn't possible to list module names more than once. We have multiple tests reusing the same providesModule ids and using System.import with modules that only exist virtually within that test. Splitting up the strings makes the regexes work (we do the same kind of splitting on www sometimes if we need to) and using different providesModule names in different test files fixes the problem. I think the BundlesLayoutIntegration-test is going to be deleted, so this doesn't even matter.

Fixes a terrible bug due to which when Hot Loading enabled when the user reloads we'll serve them the first `hot` bundle he requested. This happened because when HMR enabled we bailed out after sending the HMR updates and didn't rebuild any of the bundles the user requested before. As a consequence, when they reload we'd sent him the first and only one we ever built.
The fix is to tweak the hmr listener to return a promise. This way we can run the remaining code on the file change listener just after the HMR stuff finishes. We need to do it this way to avoid the remaining stuff to compete for CPU with the HMR one and give the best possible experience when HMR is enabled.

Summary:

We want to support Hot Loading on the packager itself instead of on the transformer. This will allow us to enable it on OSS (and for any scripting language, yay!).
For now to enable Hot Loading the packager's internals transforms need to be manually enabled (start packager with `--enable-internal-transforms`). I think the internal pipeline should always be enabled as it doesn't affect performance if there're no transforms and the user can disable Hot Loading through the setting on the app though. I'll tweak this on a follow up commit.

Summary:

Before this diff we were only accepting the module that was modified but the user. This works fine as long as the user doesn't modify the dependencies a module has but once he starts doing so the HMR runtime may fail when updating modules' code because they might might a few dependencies. For instance, if the user changes the `src` a `Image` has to reference an image (using the new asset system) that wasn't on the original bundle the user will get a red box. This diff addresses this by diffing the modules the app currently has with the new ones it should have and including all of them on the HMR update. Note this diffing is only done when the we realize the module that was modified changed it's dependencies so there's no additional overhead on this change.

Summary:
public
This diff introduces an internal transforms pipeline that integrates with the external one. This has been a feature we've been looking to implement for a long time to use babel instead of `replace` with regexps on many parts of the packager.
Also, to split the bundle we'll need to run one transform. Internally for Facebook we can run the system-import transform altogether withe the other ones. For OSS we offer `transformer.js` which people can use out of the box if they're writing ES6 code. For those people, `transformer.js` will also run the internal transforms`. However they might want to tune the transforms, or even write the code on another language that compiles to Javascript and use a complete different transformer. On those cases we'll need to run the external transforms first and pipe the output through the internal transforms. Note that the order it's important as the internal transforms assume the code is written in JS, though the original code could be on other scripting languages (CoffeeScript, TypeScript, etc).

Summary:
We don't (yet) treat these the same as any other modules because we still have special resolution rules for them in the packager allowing the use of `providesModule`, but I believe this allows people to use npm react in their RN projects and not have duplicate copies of React. Fixesfacebook/react-native#2985.
This relies on fbjs 0.6, which includes `.flow` files alongside the `.js` files to allow them to be typechecked without additional configuration. This also uses react 0.14.5, which shims a couple of files (as `.native.js`) to avoid DOM-specific bits. Once we fix these in React, we will use the same code on web and native. Hopefully we can also remove the packager support I'm adding here for `.native.js`.
This diff is not the desired end state for us – ideally the packager would know nothing of react or fbjs, and we'll get there eventually by not relying on `providesModule` in order to load react and fbjs modules. (fbjs change posted here but not merged yet: https://github.com/facebook/fbjs/pull/84.)
This should also allow relay to work seamlessly with RN, but I haven't verified this.

Summary:
public
Before this this when a file was changed besides sending the HMR update we rebuild every single bundle that the packager had build (to serve it faster when the user hit cmd+r). Since when hot loading is enabled we don't do cmd+r all this work was pointless (except for when you're developing multiple apps using the same packager instance at the same time, which we can assume is very uncommon). As a consequence, the HMR update was competing with the rebundling job making HMR quite slow (i.e.: on one huge internal app it took up to 6s for the HMR changes to get applied).
So, this diff tweaks the file change listener so that we don't rebundle nor invoke the fileWatchers (use for live reload which is also useless when hot load is enabled) when hot loading is enabled. Also, it makes the HMR listener more high pri than the other listeners so that the HMR dev experience is as good as it can get.

Summary:

Implement all the necessary glue code for several diffs submitted before to get Hot Loading work end to end:
- Simplify `HMRClient`: we don't need to make it stateful allowing to enable and disable it because both when we enable and disable the interface we need to reload the bundle.
- On the native side we introduced a singleton to process the bundle URL. This new class might alter the url to include the `hot` attribute. I'm not 100% sure this is the best way to implement this but we cannot use `CTLSettings` for this as it's are not available on oss and I didn't want to contaminate `RCTBridge` with something specific to hot loading. Also, we could potentially use this processor for other things in the future. Please let me know if you don't like this approach or you have a better idea :).
- Use this processor to alter the default bundle URL and request a `hot` bundle when hot loading is enabled. Also make sure to enable the HMR interface when the client activates it on the dev menu.
- Add packager `hot` option.
- Include gaeron's `react-transform` on Facebook's JS transformer.
The current implementation couples a bit React Native to this feature because `react-transform-hmr` is required on `InitializeJavaScriptAppEngine`. Ideally, the packager should accept an additional list of requires and include them on the bundle among all their dependencies. Note this is not the same as the option `runBeforeMainModule` as that one only adds a require to the provided module but doesn't include all the dependencies that module amy have that the entry point doesn't. I'll address this in a follow up task to enable asap hot loading (9536142)
I had to remove 2 `.babelrc` files from `react-proxy` and `react-deep-force-update`. There's an internal task for fixing the underlaying issue to avoid doing this horrible hack (t9515889).

Summary:
There's quite a bit of code scattered around the packager regarding ignoring the `providesModule` Haste pragma in any file that isn't in `react-native`, `react-tools` or `parse`. There is even a (passing) test case.
However, there's an edge case.
Take, for example, `fbjs`. It has a module inside of it called `ErrorUtils`. `react-relay` requires this file normally, in Common.JS style, by doing `require('fbjs/libs/ErrorUtils')`. But when `react-native` attempts to require `ErrorUtils` using the HasteModule format (in it's JavaScript initialization), it resolves the `fbjs` `ErrorUtils` module, instead of RN's `ErrorUtils`.
This happens, it turns out, because when a module is read (in `Module._read`), it's not caring about whether or not it should pay attention to `providesModule`, and is just assigning the `providesModule` value as the id of the module no matter what. Then when `Module.getName` is called, it will always use that `data.id` that was set, thus creating the wrong dependency tree.

Summary:
Currently, the app server accepts `transformModulePath` which allows us to use different transformation variants. However, these options persist through the lifetime of the server. So we cannot conditionally transform a module differently for two bundles without restarting the server with different options.
`getTransformOptions` basically allows us to change the options to the transformer at runtime based on the bundle and module being transformed.
These options are also used as a cache key for the transformedSource to ensure that if a file is transformed with different options, caching doesn't cause any inconsistencies.

Introduce a new Polyfill module to load bundles. This polyfill contains the function to which System.import gets transformed into. It works similarly to require in the way it's registered. It keeps track of the bundles that have ever been requested using promises, either fulfilled or not. The use of promises makes the implementation quite easy as we don't need to differenciate whether the request has been started or not.
There're a couple of follow up steps that still need to get done:
- Included this polyfill on the ones we automatically include on the bundle.
- Modify the transform to include the modules the user is actually requesting and pipe that through loadBundles so that the promise, once resolved, has the ordered list of modules the user requested.
- Implement the actual native code that loads a bundle. This shouldn't be that taught as native will be able to assume it will never receive the same request twice.

In fact, I think we'll eventually start treating polyfills as normal modules just like core-js.

```
on the other hand, if "react-native" is not present in package.json, you should fall back to "browser"
other than the one (nesting) test added, the tests are unchanged, just done for both "react-native" and "browser"
(I've implemented [react-native-udp](https://npmjs.org/package/react-native-udp) and [react-native-level-fs](https://npmjs.org/package/react-native-level-fs), but they obviously don't belong in the traditional "browser" field as they won't run anywhere except in React Native.)

Summary: This adds a build option for using Prepack (an experimental packager) to
build a bundle. It doesn't actually take on the npm package dependency
because it's not published/open source (yet).
This will be used while we experiment and should be maintained as the
build system changes so that we can continue getting fresh builds.
I found that saveBundleAndMap and processBundle were over abstracted and
got in my way so I inlined it and removed the unit tests because the unit
test was testing trivial code that is likely to change interface.
I went with a separate build phase and a separate Bundle class even though
there are a lot of commonalities. I imagine that the requirements for
Prepack will continue to diverge. Especially for source maps but a larger
refactor could try to unify these a bit more. The fact that modules are
wrapped before the write phase seems to be an unfortunate architecture
that makes this difficult.

Summary: I'm planning to split up `DependencyResolver` into the react-native specific implementation of it and a new, generic resolver that is going to replace `node-haste` for jest and other places where we might need JS dependency resolution.
The plan is to split the two folders up so that:
* `Resolver` is the folder for all the react-native specific resolver code
* `DependencyResolver` will become a standalone library, eventually moving into a package called `node-haste`.
There is still a lot to be figured out. This is just the first diff of likely many. The current goal is to make `DependencyResolver` standalone to be able to create an instance of a resolver and resolve all dependencies for a file. This is when I can start integrating it more seriously with jest.
This diff simply moves a bunch of things around and turns `HasteModuleResolver` into an ES2015 class ( :) ).

Summary: @public
This was a hard one, bare with me on the full story of what happened.
We recently started writting additional JS scripts in ES6 for the cli. These code needs to be transformed by babel before we execute it as we don't run node with `--harmony`. To do so we removed the `only` attribute on the `babel-register`. Turns out this broke the packager on oss as if no `only` not `ignore` parameter is specified babel will ignore `node_modules`. Since on oss when a project is created `react-native-github` is located inside of `node_modules` we started getting syntax errors.
The fix is to include separately all the different paths we need to make sure babel transforms each of them. We cannot simply have a single `babel-core/register` as we need to include paths that belong both to oss and internal only. So, we need to have multiple `register` invocations. Since babel does not accumulate the `only` you send on every invocation we need to build a small wrapper to do so.

2. We see that it's alive but by the time we actually connect to it the server would've died

2. The "ping" should only disconnect once the client is connected
3. Finally, have a better error message than ENOENT

Summary:
A few potential races to fix:

2. Servers who should die because other servers are already listening are taking the socket with them (move `process.on('exit'` code to after the server is listening
3. Servers which are redundant should immediatly die
Summary:
Buck (our build system) currently starts multiple packager instances for each target and may build multiple targets in parallel. This means we're paying startup costs and are duplicating the work. This enables us to start one instance of the packager and connect to it via socket to do all the work that needs to be done.
The way this is structured:
1. SocketServer: A server that listens on a socket path that is generated based on the server options
2. SocketClient: Interfaces with the server and exposes the operations that we support as methods
3. SocketInterface: Integration point and responsible for forking off the server

Summary:
The `BundlesLayout` will be used as a persistent index. As such, it would be easier to avoid having dependencies to `Module`, `Package`, `Asset`, etc. We're not using that information for now and if we happen to need to use it we could always fetch it using the `ModuleCache`.
Summary:
We've decided to move the syntax for asynchronously requiring async dependencies. The new syntax works better with promises and therefore withe async/await as well. The new syntax looks like this: `System.import('moduleA').then(moduleA => {...});` or if you're using async/await you could simply do:
let moduleA = await System.import('moduleA');
new moduleA().someFunction();
If you need to require multiple dependencies just do:
Promise
.all([System.import('moduleA'), System.import('moduleB')])
.then((moduleA, moduleB) => {...})
or the equivalent using async/await

Fix error in the template string (no plus, thinks it's a function).
And bump the timeout to 30 seconds because a file is taking more than 10 seconds `js/RKJSModules/Libraries/FBComponents/FBFed/FeedStoryFragments.js`
Summary:
Since JS doesn't have the guarantee that once a bundle is loaded it will stay in memory (and this is something we actually don't want to enforce to keep memmory usage low), we need to keep track of parent/child relationships on the packager to pass it down to native. As part of this diff, we also introduced an ID for each bundle. The ID for a child bundle is shynthetized as the bundleID of the parent module + an index which gets incremented every time a new bundle is created. For instance given this tree:
a,b
c f
d e g
the ID for `d` will be `bundle.0.1.2`, the one for e will be `bundle.0.1.3` and the one for `g` will be `bundle.0.5.6`. This information will be useful to figure out which bundles need to be loaded when a `require.ensure` is re-written.
Summary:
There's been a case where Babel can hang indefinitely on a file parse/transform. Possibly related to https://github.com/babel/babel/issues/2211
This adds a timeout to transform jobs and throws an error informing the user of the offending file. The timeout interval defaults to 10 seconds, but can be changed via an option.
Summary:
D2319999 introduced a regression where we stopped waiting for the "build haste map" step to finish before we accept any requests. This makes sure that we block on that.
Need to unbreak with this, but will follow up with a test to catch this in the future.
Summary:
Currently the platform selection is controlled by the blacklist. However, since we want to use the same server instance for cross-platform development, we need this to be controlled per request.
One outstanding issue, is that the DependencyGraph class wasn't designed that way and it doesn't have a per-request state. This means that with the current design race conditions is possible. If we got a request for a different platfrom while processing the previous request, we may change the outcome of the previous request.
To fix this a larger refactor is needed. I'll follow up a diff to do that.
Finally, so I don't break the universe like last time, I'll leave it up to the RN guys to update the call sites.
Summary:
This sets NODE_ENV based on the value of the `dev` option when bundling the apps. This would then be inlined by the node-env-inline babel plugin. And finally -- if unreachable -- will be dead-code-eliminated by uglify.
This is not used in development because we set NODE_ENV to the value of __DEV__, which can be switched via a query param. However, the plugin has minimal overhead and to avoid complexity in the transformers I just enabled it by default.
Summary:
Not that at the moment a module can be present in multiple bundles, so the new API will return only one of them. In the near future we'll impose the invariant that a module can only be present in a single bundle so this API will return the exact bundle in which it is.
Summary:
Instead of using plain objects and having to convert to and from them we just use the `Module` class across the codebase.
This seems cleaner and can enforce the type as opposed to fuzzy objects.
Summary:
Introduce a Bundler capable of generating the layout of modules for a given entry point. The current algorithm is the most trivial we could come up with: (1)it puts all the sync dependencies into the same bundle and (2) each group of async dependencies with all their dependencies into a separate bundle. For async dependencies we do this recursivelly, meaning that async dependencies could have async dependencies which will end up on separate bundles as well.
The output of of the layout is an array of bundles. Each bundle is just an array for now with the dependencies in the order the requires where processed. Using this information we should be able to generate the actual bundles by using the `/path/to/entry/point.bundle` endpoint. We might change the structure of this json in the future, for instance to account for parent/child bundles relationships.
The next step will be to improve this algorithm to avoid repeating quite a bit dependencies across bundles.
Summary:
This is the first step to add support for splitting the JS bundle into multiple ones. This diff adds support for keeping track of the async dependencies each module has. To do so we introduce the following syntax:
require.ensure(['dep1', 'dep2, ..., 'depN'], callback);
Where the callback function is asynchronously invoked once all the indicated modules are loaded.
Internally, the packager keeps track of every set of async dependencies a module has. So for instance if a module looks like this:
require.ensure(['dep1'], () => {...});
require.ensure(['dep2'], () => {...});
the `Module` object will keep track of each set of dependencies separately (because we might want to put them on separate bundles).
Summary:
The word Package is overloaded, it may mean npm package, or may mean a collection of bundles. Neither is what we mean. We mean `bundle`.
This renames it and modernize some of the Bundler code.
Summary:
The cache is only used for JSTransformer at the moment. We're doing IO and some computation to get each module's name, whether is a haste or node module and it's dependencies. This work happens on startup so by caching this value we shouldbe able to reduce the start up time. Lets promote the Cache to the Packager level to be able to use it by any of the components of the packager. For now, on this diff we'll start using it to cache the mentioned fields.
Also we had to introduce the concept of fields in the cache as manually merging the date we had for each path is not possible as we're using promisses all around. With the new API, each field is a promise.
@amasad and I did some manual testing to measure the impact of this change and looks like it's saves 1 second when building the haste map (which represents 50% of the time). Overall this reduces 1 second of start up time which was currently about 8s on my mac book pro.
Summary:
When React DevTools is not installed, React prints a tiny warning to the console.
However, in debugger.html we have a lot of free space we could use to promote
React DevTools more actively.
Summary:
- Enables async/await in .babelrc and transformer.js
- Adds regenerator to package.json. Users still need to explicitly require the regenerator runtime -- this is so that you only pay for what you use.
- Update AsyncStorage examples in UIExplorer to use async/await
- Update promise tests in UIExplorer to use async/await in addition to the promise API

Summary:
Teach the resolver about platform-based resolution. The platform extension is inferred from the entry point.
It works for haste modules, as well as node-based resolution.
Summary:
[This is a preview diff for getting RN's tests to pass with a future version of jest that supports io.js and other future versions of Node. This can be merged once the diff to update jest is merged upstream and published.]
Updates the tests in small ways so they run on io.js with two updates:
- The Cache test which relies on Promises uses `runAllImmediates` for modern versions of Node because bluebird uses `setImmediate` instead of `process.nextTick` for Node >0.10.
Closes https://github.com/facebook/react-native/pull/1382
Github Author: James Ide <ide@jameside.com>
Test Plan: Run `npm test` with the latest version of jest.

Another Pull Request implementing the changes in issue #468 - Enabled Packager to run on Windows
This change relates to the blacklist fixes. It includes the path conversion for blacklist and changes to the default watched directory. It has no impact on Mac OSX.
Closes https://github.com/facebook/react-native/pull/893

Now that watchman perf issue was fixed we can enable watchman-based fs crawling which is faster than node.
This showed an existing issue with some files missing from the blacklist which I addressed.
Test Plan:
./fbrnios.sh run
click around and scroll all the apps
Summary:
This is an edited re-submission of #1458 because I'm stupid.
Closes https://github.com/facebook/react-native/pull/1497
Github Author: Johannes Lumpe <johannes@johanneslumpe.de>
Test Plan: Imported from GitHub, without a `Test Plan:` line.
Summary:

We have a function that detects whether a give file is to be treated as a node_modules. If so it doesn't have access to the haste module map. There is an exception to this rule which is a few modules that are allowed to do that. Currently thats react-native, react-tools, and parse.
The current implementation had a bug where if you had `react-native` (or react-tools etc) in the name before the actual package root then the detection will be off. This fixes the problem by starting from the `lastIndexOf('node_modules')` directory, that way nothing confuses us.
Test Plan:
./runJestTests.sh
export OSS, patch, run e2e test

The current output of console.log is extremely bad. If you pass NaN, it shows up as null (super confusing I know -_-), if you pass a cyclical object, it just says that it is cyclic and that's it. It doesn't print up the first few levels which are NOT cyclical and would be really helpful.
It turns out that nodejs console.log pretty printer is really awesome and can be easily extracted as a few hundred lines. This is going to be such a productivity boost that I think it's the right tradeoff to embed it like this
Test Plan:
```
var a = {kikoo: {lol: 1}}
a.kikoo.nice = a;
console.log(a);
> { kikoo: { lol: 1, nice: [Circular] } }
console.log(NaN)
> NaN
```
Summary:
Similarly to npm-installed react, this change makes changes to the packager so that it understands that it's been installed via Cocoapods and determines the project and asset roots properly (from the main application directory).

Summary:
@public
corrected small typo in the 500 response from the packager server
Test Plan: add throw to promise function prior to error handler, run packager, cache a bundle with bundle extension URI, open /debug/packages, see clean 500 error
