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:
Inline require `ExceptionsManager` dependencies which are eagerly loaded on app startup (via `setUpConsole()` which is called from `InitializeJavaScriptAppEngine.js`) even though it's necessary until an exception needs to be reported.
This can save about 30-40ms on an iOS device.

Rename the `BridgeProfiling` JS module to `Systrace`, since it's actually just
an API to Systrace markers.
This should make it clearer as we add more perf tooling.

Summary: Fix for [Issue 1331](https://github.com/facebook/react-native/issues/1331). Sets navigator.product to ReactNative and navigator.productSub to the version string in package.json.
Note that the code requires package.json, which works fine in the RN packager, but webpack users will probably a need to configure a json loader in their config file.
Tested using UIExplorer and console.log printout of the product variables in xcode and Chrome debugger.

Summary: Set up the polyfills for console and process before initializing other modules. Some modules do work (e.g. call `invariant`) when they are first required, so requiring the DefaultInjection module at the beginning ensures we have a consistent JS environment.

Summary: @public
jest is running the polyfill multiple times on the same environment (cc @cpojer, need to fix that!). By default jest doesn't have XMLHttpRequest polyfilled so it'll define a property with writable to be false. It'll fatal the second time it tries to override XMLHttpRequest.
The hacky workaround is to make properties that do not exist with writable: true. But the long term fix would be to make jest stop running the polyfill multiple times.

Fixes#773, #1055
The resolver was getting a bit unwieldy because a lot has changed since the initial writing (porting node-haste).
This also splits up a large complex file into the following:
* Makes use of classes: Module, AssetModule, Package, and AssetModule_DEPRECATED (`image!` modules)
* DependencyGraph is lazy for everything that isn't haste modules and packages (need to read ahead of time)
* Lazy makes it fast, easier to reason about, and easier to add new loaders
* Has a centralized filesystem wrapper: fast-fs (ffs)
* ffs is async and lazy for any read operation and sync for directory/file lookup which makes it fast
* we can easily drop in different adapters for ffs to be able to build up the tree: watchman, git ls-files, etc
* use es6 for classes and easier to read promise-based code
Follow up diffs will include:
* Using new types (Module, AssetModule etc) in the rest of the codebase (currently we convert to plain object which is a bit of a hack)
* using watchman to build up the fs
* some caching at the object creation level (we are recreating Modules and Packages many times, we can cache them)
* A plugin system for loaders (e.g. @tadeuzagallo wants to add a native module loader)
Test Plan:
* ./runJestTests.sh react-packager
* ./runJestTests.sh PackagerIntegration
* Export open source and run the e2e test
* reset cache
* ./fbrnios.sh run and click around

Add PerformanceLogger to keep track of JS download, initial script execution and
full TTI.
Test Plan:
The Native side currently calls `addTimespans` when it's finish initializing
with the six values (start and end for the three events), so I just checked it
with a `PerformanceLogger.logTimespans()` at the end of the function.

Previously, our XMLHttpRequest implementation would only update the readyState when the download was fully completed. This diff adds support for receiving incremental data updates as the download happens, which can be monitored by adding the onreadystatechange event handler.
As a performance optimization, incremental data updates are only sent if the onreadystatechanged handler has been set in the JS, otherwise it just sends the whole data block once download is complete, as before.
Test Plan:
* Run the UIExplorer XMLHttpRequest example (in both OSS and Catalyst) to see incremental downloads working.
* Run the Movies app to see regular (non-incremental) downloads in action
* Run any network-based app in Catalyst shell to verify RKDataManager still works
Summary:
@public
ErrorUtils.reportError is intended for reporting handled errors to the
server, like timeouts, which means that we shouldn't shove them in the
developer's face.
Test Plan: add `require('ErrorUtils').reportError(new Error('error'))` and see a useful error message with stack but no redbox. Debugger confirms `reportSoftException` is called but it doesn't do anything yet. `reportFatalError` and throwing exceptions still show redboxes.
