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.

Compute the dependencies of the bundle entry file just before sending HMR updates. In case the file that was changed doesn't belong to the bundle bail.

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).

Add a very simple runtime for self-accepting modules. The API is the same one as Webpacks's one for now.
The new infra will be end-to-end tested on a follow up diff.

This diff adds infra to both the Packager and the running app to have a WebSocket based connection between them. This connection is toggled by a new dev menu item, namely `Enable/Disable Hot Loading`.

Using the provided WebSocket example under react-native 0.17, the sample code throws the following error:
"TypeError: ws.on is not a function(…)"
It's listening on ".on" which does not exist, rather than assigning a function to onopen, onmessage, onerror and onclose.
See: https://developer.mozilla.org/en-US/docs/Web/API/WebSocket
Summary:
I don't know the reasons, why the templates are written with the `react.createClass`method. Today I see lot's of examples using the **ES6 way**. In my own projects I'm using this way, too.
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:
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.

Passing around a `getTransformOptions` function doesn't really work with the CLI utils, so I'm changing this to `getTransformOptionsModulePath` instead, which can easily be injected in through `rn-cli.config.js`.

Summary:
Default behavior should be unchanged.
If we queue up a bunch of expensive tasks during an interaction, the default
`InteractionManager` behavior would execute them all in one synchronous loop at
the end the JS event loop via one `setImmediate` call, blocking the JS thread
the entire time.
The `setDeadline` addition in this diff enables an option to only execute tasks
until the `eventLoopRunningTime` is hit (added to MessageQueue/BatchedBridge),
allowing the queue execution to be paused if an interaction starts in between
tasks, making the app more responsive.
Additionally, if a task ends up generating a bunch of additional tasks
asynchronously, the previous implementation would execute these new tasks after
already scheduled tasks. This is often fine, but I want it to fully resolve
async tasks and all their dependencies before making progress in the rest of the
queue, so I added support for `type PromiseTask = {gen: () => Promise}` to do
just this. It works by building a stack of queues each time a `PromiseTask` is
started, and pops them off the stack once they are resolved and the queues are
processed.
I also pulled all of the actual queue logic out of `InteractionManager` and into
a new `TaskQueue` class to isolate concerns a bit.
