Summary: public
In Navigator, there are several places that mutate `this.state.presentedIndex`
with the express `this.state.presentedIndex = destIndex` instead of calling
`this.setState`, which creates the problem that not all internal states are
updated within the same React update cycle.
One of the symptoms is that over-swiping within the Navigator may throw JS error
due to `this.state.sceneConfigStack` and `this.state.presentedIndex` are not both
updated.
The workaround is to bypass the over-swiping gesture to avoid JS error.

Summary: public
The image loader was previously returning on the main thread, which could lead to poor performance due to various call sites doing further image processing (resizing, cropping, etc.) directly in the completion block.
This diff modifies the loader to return on a background thread (the same one used to load the image), and updates the call sites to dispatch to the explicit thread they need.

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
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: Adds a new option to animation configs so that animations can be marked as non-interactions. This solves the "loading indicator problem" where an animated loading screen would deadlock as it waits for all interactions to complete.
As for the API, what we really want long term is better scheduling. This needs to be built at the runtime level (into the RN bridge) and take care of things like priority donation that are probably overkill right now. Basically this API is a medium-term fix and I won't be upset if it gets replaced with a finer-grained scheduler.

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.

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.

Summary: @public
This diff unifies the logic for detecting when images refer to XCAsset files into a single function (RCTXCAssetNameForURL) and uses it for both +[RCTConvert UIImage:] and RCTImageLoader.
I've also tightened the definition of XCAssets so that it only applies to images inside .car files, not any image inside the main bundle. This avoids using the +[UIImage imageNamed:] when not strictly necessary, which is desirable since that method is not thread-safe, and has undocumented caching behavior that is difficult to reason about.

Summary: This is related to the discussion in #3155.
I've documented the methods in this mixin, and pointed to other appropriate documentation where necessary as well.
I didn't end up adding any examples. I wanted to add a `focus()`/`blur()` example to the UIExplorer app, but the app seems to be broken on master at the moment (`Requiring unknown module "event-target-shim"`) and I didn't bother trying to fix it. I think the last thing necessary for making the usage of these methods clear is an example of calling one or more of them on a `ref` or view captured in some other way. However, `setNativeProps` is well documented in the "Direct Manipulation" guide, which I link to from this page, so by extension it should be possible to figure out the functionality of the other methods.
