Summary:

Thanks to the new lazy initialization system for modules, `RCTDidCreateNativeModules` no longer does what the name implies.
Previously, `RCTDidCreateNativeModules` was fired after all native modules had been initialized. Now, it simply fires each time the bridge is reloaded. Modules are created on demand when they are needed, so most of the assumptions about when `RCTDidCreateNativeModules` will fire are now incorrect.
This diff deprecates `RCTDidCreateNativeModules`, and adds a new notification, `RCTDidInitializeModuleNotification`, which fires each time a module a new module is instantiated.
If you need to access a module at any time you can just call `-[bridge moduleForClass:]` and the module will be instantiated on demand. If you want to access a module *only* after it has already been instantiated, you can use the `RCTDidInitializeModuleNotification` notification.

A lot of the core modules have to use private methods in the bridge, specially
since the `RCTBatchedBridge` interface is never exposed. That was leading to a
lot of different private bridge categories spread across different modules,
which makes harder to identify which modules are affected by private API changes.
Replace all the categories with a single private header.

Summary:
A component can be backed by native "node" that can change its internal state, which would result in a new UI after the next layout. Since js has no way of knowing that this has happened it wouldn't trigger a layout if nothing in js world has changed. Therefore we need a way how to trigger layout from native code.
This diff does it by adding methods `layoutIfNeeded` on the uimanager and `isBatchActive` on the bridge.
When `layoutIfNeeded` is called it checks whether a batch is in progress. If it is we do nothing, since at it's end layout happens. If a batch is not in progress we immidiately do layout.
I went with the easiest way how to implement this - `isBatchActive` is a public method on the bridge. It's not ideal, but consistent with other methods for modules.

This diff replaces the RegEx module method parser with a handwritten recursive descent parser that's faster and easier to maintain.
The new parser is ~8 times faster when tested on the UIManager.managerChildren() method, and uses ~1/10 as much RAM.
The new parser also supports lightweight generics, and is more tolerant of white space.

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. ReactMethod/RCT_EXPORT_METHOD.

The +[RCTConvert UIImage:] function, while convenient, is inherently limited by being synchronous, which means that it cannot be used to load remote images, and may not be efficient for local images either. It's also unable to access the bridge, which means that it cannot take advantage of the modular image-loading pipeline.
This diff introduces a new RCTImageSource class which can be used to pass image source objects over the bridge and defer loading until later.

Summary:

Currently, we wait to invoke `-flushUIBlocks` until the JavaScript batch to native has completed. This means we may be waiting an unnecessarily long time to perform view hierarchy changes and prop changes.
By instead invoking this after each chunk of enqueued UI blocks, we can perform some updates more eagerly, increasing our utilization of the main thread while splitting up the amount of time we spend running upon it.
This shouldn't affect layout, which is still tied to `-batchDidComplete`, so any visual inconsistencies should be limited to prop changes, which seems acceptable for the dramatic improvement in performance.

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:
Previously the bridge sometimes never fired RCTJavaScriptDidLoadNotification or RCTJavaScriptDidFailToLoadNotification if there was an error (for example, if the source code loaded but we couldn't inject the JSON config). This diff moves the error handling into a method called `stopLoadingWithError` that the bridge can call whenever there is an error.
Also if the script failed to load, the BatchedBridge still called `executeSourceCode`. With this diff the `_loading` flag is set to NO when the script fails to load, and `executeSourceCode` returns immediately when `_loading` is false. This way the bridge does not try to execute JS when there is a loading error.

Summary:
When bridge calls are made, they should be dispatched to their
destination GCD queue in the same order they were made. (It
looks like this invariant broke in 336e18d, which caused call
order to depend on the iteration of `NSMapTable` keys
whenever there are calls to multiple modules that share a queue)
Fixes#1941 (in which RCTUIManager createView addUIBlock
blocks were sometimes running after other blocks that depended
on them)
I'm a react-native/iOS/objc newbie, so please excuse any
ignorance this commit may well contain :)

Summary:
The arg block for handling structs did not return a value, which was being intepreted as failure. This diff returns YES for success, and also adds an error log for this case so future regressions won't fail silently.
Summary:
There's no good reason for initialProperties to be mutable after the RCTRootView has been created. Passing it in through the constructor means we can skip one dispatch_async.
Summary:
Our events all follow a common pattern, so there's no good reason why the configuration should be so verbose. This diff eliminates that redundancy, and gives us the freedom to simplify the underlying mechanism in future without further churning the call sites.
Summary:
The module's methodQueue wasn't being created when accessing the modules directly
on the bridge, without going through JS. Preload the queue for now to fix internal
breakages, but I'll figure out a better way to keep it lazy afterwards.
Summary:
For the sake of consistency, `cmd+r` should just post a refresh notification. This way other tools can also observe and react to the refresh without ugly hacks.

Summary:
Moved the view creation & property binding logic out of RCTUIManager into a separate RCTComponentData class - this follows the pattern used with the bridge.
I've also updated the property binding to use pre-allocated blocks for setting the values, which is more efficient than the previous system that re-contructed the selectors each time it was called. This should improve view update performance significantly.
Summary:
Some of the log statements inside argument blocks in RCTModuleMethod were directly accessing ivars, thereby causing a retain cycle that retained the class. I've fixed this by making the access explicit via weakSelf.
Summary:
If the bundleURL has no port(default 80) , the profile request URL will be `<scheme>://<host>:<null>/profile`, that will not work. So we should decide if the port exsits first.
