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.

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:

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).

I removed `use strict`, since *Module code is always strict mode code*, according to the [spec](http://www.ecma-international.org/ecma-262/6.0/#sec-strict-mode-code).
Maybe we should **discuss** the usage of ES6 in the templates.

Summary:
The JavaScript ecosystem doesn't have the notion of a built-in native module loader. Even Node is decoupled from its module loader. The module loader system is just JS that runs on top of the global `process` object which has all the built-in goodies.
Additionally there is no such thing as a global require. That is something unique to our providesModule system. In other module systems such as node, every require is contextual. Even registered npm names are localized by version.
The only global namespace that is accessible to the host environment is the global object. Normally module systems attaches itself onto the hooks provided by the host environment on the global object.
Currently, we have two forms of dispatch that reaches directly into the module system. executeJSCall which reaches directly into require. Everything now calls through the BatchedBridge module (except one RCTLog edge case that I will fix). I propose that the executors calls directly onto `BatchedBridge` through an instance on the global so that everything is guaranteed to go through it. It becomes the main communication hub.
I also propose that we drop the dynamic requires inside of MessageQueue/BatchBridge and instead have the modules register themselves with the bridge.
executeJSCall was originally modeled after the XHP equivalent. The XHP equivalent was designed that way because the act of doing the call was the thing that defined a dependency on the module from the page. However, that is not how React Native works.
The JS side is driving the dependencies by virtue of requiring new modules and frameworks and the existence of dependencies is driven by the JS side, so this design doesn't make as much sense.
The main driver for this is to be able to introduce a new module system like Prepack's module system. However, it also unlocks the possibility to do dead module elimination even in our current module system. It is currently not possible because we don't know which module might be called from native.
Since the module system now becomes decoupled we could publish all our providesModule modules as npm/CommonJS modules using a rewrite script. That's what React Core does.
That way people could use any CommonJS bundler such as Webpack, Closure Compiler, Rollup or some new innovation to create a JS bundle.
This diff expands the executeJSCalls to the BatchedBridge's three individual pieces to make them first class instead of being dynamic. This removes one layer of abstraction. Hopefully we can also remove more of the things that register themselves with the BatchedBridge (various EventEmitters) and instead have everything go through the public protocol.

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: From http://developer.android.com/guide/topics/resources/runtime-changes.html
> Some device configurations can change during runtime (such as screen orientation, keyboard availability, and language). When such a change occurs, Android restarts the running Activity (onDestroy() is called, followed by onCreate()). The restart behavior is designed to help your application adapt to new configurations by automatically reloading your application with alternative resources that match the new device configuration.
However, in a React Native app, there is only a single activity for the entire app, unlike a single activity per screen in Android, and resources are not specific to orientation etc. Destroying activity means reloading the entire app. Most of the time, this is not the intended behaviour, and can cause data loss for the user if the developer doesn't disable it explicitly. I'm proposing to disable it by default.

Summary: A lot of people try to use a device as the very first thing when trying
out React Native. I've observed this at the developer workshop in Prague
and on Twitter.
However, developing on pre-API 21 devices is quite involved:
https://facebook.github.io/react-native/docs/running-on-device-android.html
I'm thinking we could recommend installing Android together with Android
studio. Android studio installs HAXM for you (hardware acceleration, without
this Google emulators are useless) and also creates and starts emulators.
So it would be quite a smooth experience similar to pressing 'Run' in Xcode.
We'd just need to integrate with Gradle so that installing the app also starts
the packager. I think that's something we should do in any case.
Probably an even better option is to build a React Native-specific tool that
lets you do everything you need: opens the Android SDK Manager, creates and
starts emulators, detects whether you have Genymotion and opens it, upgrades
node and npm etc.
