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.

Rename the `BridgeProfiling` JS module to `Systrace`, since it's actually just
an API to Systrace markers.
This should make it clearer as we add more perf tooling.

Summary:
MessageQueue no longer falls back to require. To do this we need to register all the modules in our internal unit tests. I did this codemod manually.
This is a bit unfortunate boilerplate but there are very few of these modules outside of unit tests. This boilerplate is only a hassle for these test files.

This PR was created in response to feedback from an older PR: https://github.com/facebook/react-native/pull/2045
The `.interpolate()` API of Animated values is quite effective to accomplish transformations based on a single animated value, but currently there is a class of animations that is impossible: animations being driven by more than one value.
Usage would be like the following:
```js
getInitialState: function() {
return {
panY: new Animated.Value(0),
offset: new Animated.Value(0),
};
}
```
```js
var scale = Animated.add(panY, offset).interpolate({
inputRange: [...],
outputRange: [...],
});
```
I have a real use case for this, and I cannot think of any way to accomplish what I need without an API like this.
The animation I am trying to accomplish is I have a PanResponder being used to detect both x and y panning. The y-axis panning drives a 3d sroll-like animation (which we can call `panY`), and the x-axis panning is driving a "swipe-to-remove" animation (

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:
Functions from the path module return paths with the native file system path separator. generateAssetModule is using path.join and path.dirname to generate httpServerLocation. That means that on Windows systems, the generated URL path has backslashes rather than forward slashes which breaks the app's ability to retrieve image assets using require('./image.png'). This change fixes this by checking path.sep and replacing backslashes with slashes on systems that require it.
