Summary:
This decouples non-UI logic from RCTDevMenu into a new module RCTDevSettings.
**Motivation**: This allows developers to change dev settings without depending on the built-in dev menu, e.g. if they want to introduce their own UI, or have other devtools logic that doesn't depend on an action sheet.
It also introduces the RCTDevSettingsDataSource protocol for storing dev tools preferences. This could allow a developer to implement alternative behaviors, e.g. loading the settings from some other config, changing settings based on the user, deciding not to persist some settings, or something else.
The included data source implementation, RCTDevSettingsUserDefaultsDataSource, uses NSUserDefaults and is backwards compatible with the older implementation, so **no workflows or dependent code will break, and old saved settings will persist.**
The RCTDevMenu interface has not changed and is therefore also backwards-compatible, though
some methods are now deprecated.
In order to ensure that RCTDevSettings

`RCTWebSocketExecutor` saves every WebSocket callback when sending message to chrome, but does not clear them in a debug session until the JS bridge is reloaded, and there may be thousands of blocks saved in the callback table. This PR removes them after they are called.

Summary:
To make React Native play nicely with our internal build infrastructure we need to properly namespace all of our header includes.
Where previously you could do `#import "RCTBridge.h"`, you must now write this as `#import <React/RCTBridge.h>`. If your xcode project still has a custom header include path, both variants will likely continue to work, but for new projects, we're defaulting the header include path to `$(BUILT_PRODUCTS_DIR)/usr/local/include`, where the React and CSSLayout targets will copy a subset of headers too. To make Xcode copy headers phase work properly, you may need to add React as an explicit dependency to your app's scheme and disable "parallelize build".

Summary:
As per https://twitter.com/olebegemann/status/738656134731599872, our use of "main thread" to mean "main queue" seems to be unsafe.
This diff replaces the `NSThread.isMainQueue` checks with dispatch_get_specific(), which is the recommended approach.
I've also replaced all use of "MainThread" terminology with "MainQueue", and taken the opportunity to deprecate the "sync" param of `RCTExecuteOnMainThread()`, which, while we do still use it in a few places, is incredibly unsafe and shouldn't be encouraged.

Summary:The 200ms timeout was causing resource issues and causing a lot of overhead when you're not running the devtools, since it will basically create a new socket every 200ms.
Also clean up the way we do logging so it's completely compiled out in prod, and standardize all the names we use for threading to lowercase react.

Summary:
`debugger.html` contained a ton of hacky code that was needed to ensure we have a clean JS runtime every time a client RN app connects. That was needed because we used the page's global environment as runtime. Some time ago WebWorker support was added and now we run RN code inside an isolated WebWorker instance, and we can safely get rid of all these hacks.
This has a bunch of nice side-effects: debug reload works faster, `console.log`s are preserved, `debuggerWorker.js` selection doesn't change.
Made sure the debugging (breakpoints, etc.) still works as before.

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: public
The `bridge.modules` dictionary provides access to all native modules, but this API requires that every module is initialized in advance so that any module can be accessed.
This diff introduces a better API that will allow modules to be initialized lazily as they are needed, and deprecates `bridge.modules` (modules that use it will still work, but should be rewritten to use `bridge.moduleClasses` or `-[bridge moduleForName/Class:` instead.
The rules are now as follows:
* Any module that overrides `init` or `setBridge:` will be initialized on the main thread when the bridge is created
* Any module that implements `constantsToExport:` will be initialized later when the config is exported (the module itself will be initialized on a background queue, but `constantsToExport:` will still be called on the main thread.
* All other modules will be initialized lazily when a method is first called on them.
These rules may seem slightly arcane, but they have the advantage of not violating any assumptions that may have been made by existing code - any module written under the original assumption that it would be initialized synchronously on the main thread when the bridge is created should still function exactly the same, but modules that avoid overriding `init` or `setBridge:` will now be loaded lazily.
I've rewritten most of the standard modules to take advantage of this new lazy loading, with the following results:
Out of the 65 modules included in UIExplorer:
* 16 are initialized on the main thread when the bridge is created
* A further 8 are initialized when the config is exported to JS
* The remaining 41 will be initialized lazily on-demand

Summary: public
Benchmarking our startup path has shown we spend a lot of time decoding strings (iPhone 4S / iPhone 5):
* reading a 2MB JS bundle: 35ms / 15ms
* decoding is to an `NSString`: 186ms / 78ms
* transforming that to a `JSString`: 29ms / 10ms
Instead of going through an `NSString` transformation, we generate a null-terminated bundle (0.1ms / 0.05ms to copy the data) and use `JSStringCreateWithUTF8CString` (121ms / 53ms) to generate the string. That makes decoding 70% faster.

Summary:
Add a new bridge delegate protocol to allow a more flexible bridge configuration.
For now it just support the pre-existent configurations + providing the JavaScript
source to the bridge, that should allow pre-loading sources.
Summary:

the bridge was refactored into `RCTBridge` and `RCTBatchedBridge`.

I've increased the warning levels in the OSS frameworks, which caught a bunch of minor issues. I also fixed some new errors in Xcode 7 relating to designated initializers and TLS security.
Test Plan:
* Test the sample apps and make sure they still work.
* Run tests.
Summary:

`-[RCTJavaScriptExecutor executeBlockOnJavaScriptQueue:]` would always `dispatch_async`
for the WebView and WebSocket executors, what caused for any frame aligned dispatch.
Test Plan:
Test the `Timers, TimerMixin` example on UIExplorer, `requestAnimationFrame` was
taking ~33.3ms when debugging, now takes ~16.6ms as expected.
Summary:
@public
This is the first of a few diffs that change the way the executors are handled
by the bridge.
For they are just promoted to modules, so they are automatically loaded by the bridge.
Test Plan:
Tested on UIExplorer, Catalyst and MAdMan.
Tested all the 3 executors, everything looks fine.
