Summary:
Fix the `path.sep` replacement for Windows, currently it just replace one segment:
```js
// Result: './lib/random\random-byte.js'
'./lib\\random\\random-byte.js'.replace(path.sep, '/')
```
Change to regex will work fine:
```js
// Result: './lib/random/random-byte.js' (correct)
'./lib\\random\\random-byte.js'.replace(new RegExp('\\' + path.sep, 'g'), '/')
```

Summary:
`declareOpts` is weakly typed. Since the callsite of Resolver constructor is itself flowifyed, we can get rid of `declareOpts`, and this provides us with much better typing.
Eventually I'd like to get rid of most of the defaults in the packager's inner code (ex. `watch` being false, `dev` being true). The reason is that defaults everywhere are prone to causing inconsistencies (for ex. some other code could have `dev` as false by default), problems that cannot be caught by Flow. Instead of having non-required options, I believe it is more sensible to provide helper functions that build sets of default options.

This code is a bit sloppy, I need to rethink about it. So I prefer to remove it altogether for now.
The problem with this is that it is disabling the global cache "put" operations at the same time, so the script supposed to update the cache actually doesn't do the job past the fist few hundred files. This defeats the purpose of the global cache.

Summary:
This changes the way that module identifiers are replaced with numeric ids so that ids are padded with spaces on the right to take up the same space as the original string literal.
By doing this, we keep the mappings for the generated source line intact.
```
// original source
const React = require('react');
// old replacement
const React = require(12 /* react */);
// new replacement
const React = require(12 ); // 12 = react
```
The remaining edge case are module names that are replaced with numeric IDs that are longer than the replaced string, e.g.:
```
const Q = require('q');
const Q = require(1234);
```

Summary:
This kills fastfs in favor of Jest's hasteFS. It gets rid of a ton of code, including the mocking code in ResolutionRequest which we don't need any more. Next step after this is to rewrite HasteMap, ModuleCache, Module/Package. We are getting closer to a nicer and faster world! :)
Here is what I did:
* Use Jest's HasteFS instead of fastfs. A fresh instance is received every time something changes on the FS.
* HasteFS is not shared with everything any more. Only one reference is kept in DependencyGraph and there are a few smaller functions that are passed around (getClosestPackage and dirExists). Note: `dirExists` now does fs access instead of an offline check. This sucks but stat calls aren't slow and aren't going to be a bottleneck in ResolutionRequest, I promise! When it is time to tackle a ResolutionRequest rewrite with jest-resolve, this will go away. "It gets worse before it gets better" :) The ModuleGraph equivalent does *not* do fs access and retains the previous way of doing things because we shouldn't do online fs access there.
* Add flow annotations to ResolutionRequest. This required a few tiny hacks for now because of ModuleGraph's duck typing. I'll get rid of this soon.
* Updated ModuleGraph to work with the new code, also created a mock HasteFS instance there.
* I fixed a few tiny mock issues for `fs` to make the tests work; I had to add one tiny little internal update to `dgraph._hasteFS._files` because the file watching in the tests isn't real. It is instrumented through some function calls, therefore the hasteFS instance doesn't get automatically updated. One way to solve this is to add `JestHasteMap.emit('change', …)` for testing but I didn't want to cut a Jest release just for that. #movefast
(Note: I will likely land this in 1.5 weeks from now after my vacation and I have yet to fully test all the product flows. Please give me feedback so I can make sure this is solid!)

**Motivation**
In the context of a webview, one may extract assets (javascript or any types really), and relates to them through the html.
The packager `Server` serves this files correctly but also applies a cache based on time (a year). During development, this cache is actually bad as we need to re-iterate the process of editing/testing quickly.
I don't believe it is necessary to cache, and still wanted to make sure we would if process.env.NODE_ENV is 'production'.

Summary:
This is the next incremental step to rewrite node-haste. I apologize for the size of this diff but there is really no smaller way to do this. The current architecture passes a single file watcher instance into many classes that each subscribe to file changes. It's really hard to keep track of this. The new implementation reduces the listeners to two (will eventually be just one!) - one in DependencyGraph and one in it's parent's parent's parent (ugh! This doesn't make any sense). This should make it much more straightforward to understand what happens when a file changes.
I was able to remove a bunch of tests because jest's watcher takes care of things like ignore patterns. Some of the tests were specifically testing for whether the change events were invoked and they are now much more straightforward as well by manually invoking the `processFileChange` methods.

Summary:
The new Packager/Buck integration passes module factory functions as first argument, so that the complete call can be amended at the end safely at a later point in time.
The call expression as a whole is covered perfectly by the created source map. Appending to that code later won’t break mappings.
`__d` now also accepts an additional `dependencyMap` parameter, which so far is only used by the new Packager/Buck integration. It enables module-local dependency IDs, thus eliminating the need to insert `correct` module IDs when building a bundle. Advantages are that source maps are no longer affected, and that builds can be quicker.

Summary:
This creates flow types for the module resolution code in node-haste, and implementations of types used by that code.
The idea is to use that code until we can replace it with something leaner, and provide objects that don’t touch the file system. These objects will be initialized with the static data provided by ModuleGraph/worker.

Summary:
Context: I'm trying to add support for sending packager progress events to the client that is downloading the bundle over HTTP multipart response.
The idea is for the client to send `Accept: multipart/mixed` header, and if present the server will stream progress events to the client. This will ensure the change is backwards-compatible - the clients who don't know about progress events won't receive them.
In the future we can use this approach to download RAM bundle modules in one request.

Summary:
React native's reload javascript option doesn't always work on iOS devices since version 0.29, as described in https://github.com/facebook/react-native/issues/9617
It only doesn't work when you have a mac on a wireless connection, because react-native-xcode.sh can't find your IP address correctly in this case and will just fallback to use the pre-bundling option on your app.
This small change in react-native-xcode.sh fixed this issue for our project and should fix this issue for all mac users that use wireless connection and that will run a debug version of the app on a real iOS device.

Summary:
We could probably relieve a lot of pain (in [this issue](https://github.com/facebook/react-native/issues/4968) specifically) by fixing the error message for when a module cannot be resolved after trying every relevant `node_modules` directory.
Currently, you get a confusing error message that only gives you the last `node_modules` directory checked. By creating the error message where we can access the `searchQueue`, we're able to provide all of the attempted `node_modules` directories.
Here's an example error message:
```
Unable to resolve module leftpad from /Users/aleclarson/ReactProject/src/stuff/index.js:
Module does not exist in the module map or as these directories:

Summary:
Adds a new URL option to the packager server called "assetPlugin". This can be a name of a Node module or multiple Node modules (`assetPlugin=module1&assetPlugin=module2`). Each plugin is loaded using `require()` and is expected to export a function. Each plugin function is invoked with an asset as the argument. The plugins may be async functions; the packager will properly wait for them to settle and will chain them.
A plugin may be used to add extra metadata to an asset. For example it may add an array of hashes for all of the files belonging to an asset, or it may add the duration of a sound clip asset.

Hi,
This PR fixes the problem described by chrisnojima in https://github.com/facebook/react-native/issues/9581#issuecomment-243766310
**Test plan**
In development mode,
- Run an app with an image: `<Image source={ require('./logo.png') }/>`
- Notice that you see the following in packager console:
```txt
6:46:42 PM] <START> processing asset request logo.png
[6:46:42 PM] <END> processing asset request logo.png (1ms)
```
- Reload the app, or navigate to another page of the app with the same image
- Notice that you see again:
```txt
6:47:23 PM] <START> processing asset request logo.png
[6:47:23 PM] <END> processing asset request logo.png (1ms)
```
Now wih the fix applied,
notice that you only see `logo.png` fetched once, even if you reload or show the same image in a different part of the app.
Let me know what you think.

Summary:
This piece of code can assemble all transitive dependencies of a set of entry modules. It is supposed to replace `ResolutionRequest.getOrderedDependencies`.
It has the following advantages:
- has minimal API surface to other components of the system (uses two functions, exposes one function)
- allows to separate concerns into loading + transforming files, resolving dependencies, gathering all modules belonging to a bundle (this code), and bundling
- allows to specify multiple entry points
- allows to use any kind of dependency ID as entry point (haste IDs, node module IDs, relative paths, absolute paths – depends on the resolver)
- allows to skip files, which allows callers to incrementally update previously retrieved collections of modules

Summary:
We have a weak build machine for React Native app: a poor Mac Book Air with HDD, which is very slow.
So, fs operations sometimes fail because of timeout.
We likely don't care about build time, but it's pretty annoying to restart builds sometimes.
In this PR I make timeout injectable via environment variable.
__USAGE__:
export this variable into environment. It's measured in miliseconds.
Example, for 1 minute timeout:
`export REACT_NATIVE_FSOP_TIMEOUT=60000`
If you don't specify it, it will remain default value: `15000`
This should not break anything, but repair slow builds.

Summary:
This PR solves a problem when video assets are used from third-party React Native components (e.g. [react-native-video](https://github.com/brentvatne/react-native-video). The video will not work while the assets are served from the react native packager because the used video component (iOS) relies on HTTP range requests.
I added a small fix that allows ranged requests (e.g. mp4) to be served in ranges.
To test this:
1. make new react native project
1. add [react-native-video](https://github.com/brentvatne/react-native-video) to xcode project
1. add video component to your project
```
import Video from 'react-native-video';
var resolveAssetSource = require('react-native/Libraries/Image/resolveAssetSource');
/* ... /*
render() {
let source = resolveAssetSource(require('./someVideoFile.mp4')) || {};
return <Video /*....*/ source={source} />;
}
```
That should not work (if video is smaller than a few megabytes, open app a few times). Then add my fix, that should do the trick.

* Make the bridge config configurable so that when we disable automocking and we reset the registry we can redefine the value.
Oh also, stop using lodash in Server.js. First off, lodash 3 doesn't work in Jest's node env because it does some crazy stuff, second because we don't need to load all of lodash for debounce.

Summary:
This will allow consumers to supply their own transformer to all `react-native` cli commands by simply implementing `rn-cli.config.js` and overriding `getTransformModulePath()`. That way they don't have to fork various parts of the iOS and Android build system that React Native already provides just to add a `--transformer` command line argument.
**Test plan:** Applied this patch to the React Native version in my app, implemented `getTransformModulePath()` in my `rn-cli.config.js`, and verified that my custom transformer is invoked.

Summary:
When an asset is included in a module, and the directory for that asset can't be found in any of the roots, it is hard to debug that, because the error message contains neither the name of the requested file, the sub directory it is located in, nor the roots that have been searched for it. It becomes more difficult, because that exception is created asynchronously. It contains the calling promise code.
This diff makes the error message more useful by including the name of the file, the sub directory, and the roots.

This makes sure that `getModuleId` is called on modules in the order returned by `node-haste`, rather than waiting for a couple of promises to resolve before calling the function.

When trying to access the debug dependency graph through the `/debug/graph` endpoint of the packager server (documented in the packager README and listed as well when hitting the root `/debug` endpoint), all I am getting back is a nasty HTTP 500 error :'(
What triggers this HTTP 500 is a `TypeError` being thrown while trying to access a function that doesn't exists (anymore). Here is the error log of the packager when trying to access this endpoint :

Summary:
When remote debugging is enabled, stack traces start at `/debuggerWorker.js`. Since this is not a valid bundle URL, the packager fails to decipher it to find its sourcemap.
This changes the packager to skip the `/debuggerWorker.js` stack frame if one exists.

Summary:
This separates the babel config of the local-cli and the packager from the one used by the transforms of the packager since it doesn't run in the same environment and the local-cli/packager doesn't require react specific transforms and runs in node 4 so we can also avoid some es2015 transforms that node already supports.
I had to move the code in cli.js so it can still run in node 0.12 that doesn't support `const` since it is no longer transformed.
**Test plan**
Run the local-cli on node 0.12 and there should be a message saying that it requires at least node 4.
Run the local-cli on node 4 and 5 and everything should work the same as before.
I was also hoping for some perf gains but there was nothing noticeable. I did benchmark the babel-register call and it stayed pretty much the same. As for runtime performance it can help if there are optimisations for es2015 features in node.

Summary:
The way we currently symbolicate JS stack traces in RN during development time
(e.g. inside the RedBox) is the following: we download the source map from RN,
parse it and use `source-map` find original file/line numbers. All happens
inside running JSC VM in a simulator.
The problem with this approach is that the source map size is pretty big and it
is very expensive to load/parse.
Before we load sourcemaps:
{F60869250}
After we load sourcemaps:
{F60869249}
In the past it wasn't a big problem, however the sourcemap file is only getting
larger and soon we will be loading it for yellow boxes too: https://github.com/facebook/react-native/pull/7459
Moving stack trace symbolication to server side will let us:
- save a bunch of memory on device
- improve performance (no need to JSON serialize/deserialize and transfer sourcemap via HTTP and bridge)
- remove ugly workaround with `RCTExceptionsManager.updateExceptionMessage`
- we will be able to symbolicate from native by simply sending HTTP request, which means symbolication
can be more robust (no need to depend on crashed JS to do symbolication) and we can pause JSC to
avoid getting too many redboxes that hide original error.
- reduce the bundle by ~65KB (the size of source-map parsing library we ship, see SourceMap module)

Summary:
This pull request is a prerequisite to enabling the react-native-windows platform extension.
In the Resolver component, we need to add 'windows' to the list of platforms that are allowed in the DependencyGraph. We also need to add 'react-native-windows' (the name of the Windows platform extension NPM module) to the `providesModuleNodeModules` option. This allows the node_module folder check in the DependencyGraphHelper from node-haste to be bypassed for *.windows.js files in the Windows NPM package.
For good measure, I also included a change to blacklist.js to ensure .windows.js files are ignored when the packager is parameterized on a platform.

Putting this up as request for comments.
The PR adds [transform-react-jsx-source](https://github.com/babel/babel/tree/master/packages/babel-plugin-transform-react-jsx-source) to the list of plugins that come by default with the `react-native` preset. It will enable the use of a bunch of really cool tooling around JSX, however those are generally useful only in development mode. Is changing `react-native` preset the right thing to do in this case? Is there a way to enable this transform only in DEV? Should I add this somewhere else?

Summary:
This got broken recently. As a result of this, when a module throws while being required, either by regular load or hot reload, the module object is marked as `hasError`. Form that point all subsequent HMR updates will fail because it will think the module failed while executing the factory but the failure could have been on an old run of an old factory.
The fix is very simple: just reset `hasError` to false when accepting a module.

We recently started cleaning out the factory function after module are required to save some memory. This broke HMR on some edge cases because sometimes the factory function may need to be re-executed. This PR just wraps the optimization into `__DEV__` to make sure we don't use it while developing.
