Summary:We found that moving the preloaded modules to the startup section of the RAM Bundle improves TTI quite a bit by saving lots of through the bridge calls and injecting multiple modules at once on JSC. However, doing this on a non hacky way required a lot of work. The main changes this diff does are:
- Add to `BundleBase` additional bundling options. This options are fetched based on the entry file we're building by invoking a module that exports a function (`getBundleOptionsModulePath`).
- Implement `BundleOptions` module to include the `numPreloadedModules` attribute as a bundle additional option. This value is computed by getting the dependencies the entry file has and looking for the first module that exports a module we don't want to preload. The `numPreloadedModules` attribute is then used to decide where to splice the array of modules.
- Additional kung fu to make sure sourcemaps work for both preloaded and non preloaded modules.

This is affecting master as of 3/20. If we don't land this before v0.23 is cut we'll have to cherry pick it. This rev does *not* need to be picked on v0.22.

Summary:This adds support for source maps that can be used for “random access modules” / “unbundles”
- source maps contain an extra custom field: `x_facebook_offsets`
- this field maps module IDs to line offsets
- the source map is built as if all files were concatenated
Decoding/symbolication works as follows:
- when decoding a stack trace, and a stack frame comes from a filename that contains only numbers and ends with `.js`, look up the additionally needed line offset in the offset map and add it to the original line of the stack frame.
- consume the source map as usual

Summary:This brings back "Use numeric identifiers when building a bundle", previously backed out.
This version passes on the correct entry module name to code that decides transform options.
Original Description:
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.

Summary:This rev adds support for production sourcemaps on RAM.
When we inject a module into JSC we use the original `sourceURL` and specify the `startingLineNumber` of the module relative to a "regular" bundle. By doing so, when an error is thrown, JSC will include the provided `sourceURL` as the filename and will use the indicated `startingLineNumber` to figure out on which line the error actually occurred.
To make things a bit simpler and avoid having to deal with columns, we tweak the generated bundle so that each module starts on a new line. Since we cannot assure that each module's code will be on a single line as the minifier might break it on multiple (UglifyJS does so due to a bug on old versions of Chrome), we include on the index the line number that should be used when invoking `JSEvaluateScript`. Since the module length was not being used we replaced the placeholder we have there for the line number.

Summary:Make packager transform files before extracting their dependencies.
This allows us to extract dependencies added by transforms (and to avoid including them manually).
It also allows for better optimization and to get rid of the “whole program optimization” step:
This diff utilizes the new worker introduced in D2976677 / d94a567 – that means that minified builds inline the following variables:
- `__DEV__` → `false`
- `process.env.NODE_ENV` → `'production'`
- `Platform.OS` / `React.Platform.OS` → `'android'` / `'ios'`
and eliminates branches of conditionals with constant conditions. Dependency extraction happens only after that step, which means that production bundles don’t include any modules that are not used.

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.
