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.

Summary: I was just implementing push notifications for my iOS app and was very confused why the `register` event wasn't working.
[Eventually I ran across this tutorial](https://medium.com/@DannyvanderJagt/how-to-use-push-notifications-in-react-native-41e8b14aadae) that explained that I needed to update my AppDelegate to make that event work.
I've updated the documentation to include that note within the actual file.

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.

I fixed some callers.
Setting props the normal way used to ignore these. Unfortunately we can't

Summary: Decouple processStyle from the main reconciliation. It is now a process
extension to the style attribute `transform`. This effectively decouples a
large portion of special cases and helper dependencies from the reconciler.
The transform attribute becomes translated into the transformMatrix attribute on
the native side so this becomes a little weird in that I have to special case
it. I don't think it is worth while having a general solution for this so I
intend to rename the native attribute to `transform` and just have it accept the
resolved transform. Then I can remove the special cases.
The next step is generalizing the flattenStyle function and optimizing it.

Summary: Move the ViewAttributes and StyleAttributes configuration into the
Components library since they're coupled and change with the
native component configuration.
This also decouples StyleAttributes from the reconciler by adding it
to the ReactViewAttributes.
To do that, I refactored the property diffing to allow for recursive
configurations. Now an attribute configuration can be a nested object,
a custom configuration (diff/process) or true.
The requireNativeComponent path incorrectly gets its attributes set up
on the root validAttributes instead of the nested style object.
So I also have to add the nested form. Effectively these currently allow
these attributes on props or nested.

Summary: Concolidate the creation of the "update payload" into
ReactNativeAttributePayload which now has a create
and a diff version. The create version can be used by
both mountComponent and setNativeProps. This means that
diffRawProperties moves into ReactNativeAttributePayload.
Instead of storing previousFlattenedStyle as memoized
state in the component tree, I recalculate it every
time. This allows better use of the generational GC.
However, it is still probably a fairly expensive
technique so I will follow it up with a diff that
walks both nested array trees to do the diffing in a
follow up.
This is the first diff of several steps.
