Summary:Initializing native modules can block the main thread for tens of milliseconds when it starts up, making it difficult to instantiate the bridge on demand without causing a performance blip.
This diff splits up the initialization of modules so that - although they still happen on the main thread - they don't block the thread continuously.

Summary:
Introduced in a major lazy loading refactoring: 060664fd3d.
This is especially an issue when aborting a long-lived HTTP connection used as a notification channel, as it will use 1 of the maximum 4 connections per host (default limit defined by iOS' NSURLSession).

Summary:
Opening this in a separate PR but the discussion can be viewed on #4832.
Basically, this is a native implementation and is a bit more elegant. The consensus on my previous PR was that it should be done natively rather than in JS.
There's now no maximum valid timeout value and a timeout of 0 will never time out.
ontimeout isn't implemented (yet) in this PR.

Summary:
An HTTP request may be redirected to another URL, sometimes we need to know the URL where the response comes from.
If the server is in control, we can add an HTTP header X-Request-URL for the redirect URL. However there will be cases that 3rd party services are used.
This PR retrieves the response URL from native networking module and passes to it XMLHttpRequest. The fetch API built on XMLHttpRequest also benefits from this feature.

Attempting to load an undefined URL via XMLHttpRequest produced a confusing error deep within the network layer. This diff improves the networking stack to catch such errors earlier, and also adds a helpful error in the JS layer.

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.
(This means that you now can – and should – use types like `NSArray<NSString *> *` for your exported properties and method arguments, instead of `NSStringArray`).

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
Added RCTDataRequestHandler, which is responsible for loading data URLs. This moves the logic for data URL handling out of RCTImageDownloader (no longer needed) and into the RCTNetwork library, where it makes more sense.
This also means that it is now possible to load data URLs via XHR, and use them for purposes other than just images.

Summary: public
There was a race condition issue in RCTDownLoadTask whereby the request handler would sometimes call one of the delegate methods before setup was complete, causing an error to be logged because the request token had not been set, and causing te request to fail because the class was not yet set up.
This diff fixes that issue by adding an explicit `start` method to RCTDownloadTask, and changing the setup order to allow for the request to call back immediately without this being treated as an error.

Summary: @public
We previously discovered that using an NSURLSessionDataTask to load local files is noticably less efficient than using regular filesystem methods.
This diff adds RCTFileRequestHandler as a replacement for RCTHTTPRequestHandler when loading local files. This reduces loading time when loading local files via XMLHttpRequest, as well as improving the performance for some image load requests.

RCTNetworking currently relies on network responses to include an accurate text encoding, otherwise it is unable to convert the response data to text unless it's encoded as UTF8.

This diff makes use of a new feature in iOS8 to detect the encoding of the text authomatically

Summary:
The bridge implementation on React Android does not currently support boxed numeric/boolean types (the equivalent of NSNumber arguments on iOS), nor does Java support Objective-C's nil messaging system that transparently casts nil to zero, false, etc for primitive types.
To avoid platform incompatibilities, we now treat all primitive arguments as non-nullable rather than silently converting NSNull -> nil -> 0/false.
We also now enforce that NSNumber * objects must be explicitly marked as `nonnull` (this restriction may be lifted in future if/when Android supports boxed numbers).
Other object types are still assumed to be nullable unless specifically annotated with `nonnull`.
Summary:
Added Gzip function to RCTUtils. This uses dlopen to load the zlib library at runtime so there's no need to link it into your project.
The main reason for this feature is to support gzipping of HTTP request bodies. Now, if you add 'Content-Encoding:gzip' to your request headers when using XMLHttpRequest, your request body will be automatically gzipped on the native side before sending.
(Note: Gzip decoding of *response* bodies is handled automatically by iOS, and was already available).
Summary:
As discussed with @nicklockwood in the issue https://github.com/facebook/react-native/issues/1780, the error should be changed to a warning to not break fetch() to send a POST to a remote API without wanting to parse the reply. E.g. google sends back an empty 1x1px gif when POSTing something to google analytics.
