Summary:
This adds new development feature to React Native that provides information
about selected element (see the demo in Test Plan).
This is how it works:
App's root component is rendered to a container that also has a hidden layer called
`<InspectorOverlay/>`. When activated, it shows full screen view and captures all
touches. On every touch we ask UIManager to find a view for given {x,y} coordinates.
Then, we use React's internals to find corresponding React component. `setRootInstance`
is used to remember the top level component to start search from, lmk if you have a
better idea how to do this. Given a component, we can climb up its owners tree
to provice more context on how/where the component is used.
In future we could use the `hierarchy` array to inspect and print their props/state.
Known bugs and limitations:
* InspectorOverlay sometimes receives touches with incorrect coordinates (wtf)
* Not integrated with React Chrome Devtools (maybe in followup diffs)
* Doesn't work with popovers (maybe put the element inspector into an `<Overlay/>`?)

Works nicely with scrollviews

Add `RCTAssertThread` to `RCTAssert.h` for convenience when checking the current/queue,
it accepts either a `NSString *`, `NSThread *` or `dispatch_queue_t` as the object to be checked
Also add a check to `-[RCTUIManager addUIBlock:]` - There was a discussion on github (https://github.com/facebook/react-native/issues/1365)
due to the weird behavior caused by calling it from a different thread/queue (it might be added after `batchDidComplete` has been called
and will just be dispatched on the next call from JS to objc)
Test Plan:
Change `-[RCTAnimationExperimentalManager methodQueue]` to return `dispatch_get_main_queue()` and run the 2048 example,
it should dispatch with a helpful message (screenshot on the comments)

Our background color propagation mechanism is designed to make rendering of translucent content more efficient by pre-blending against an opaque background. Currently this only works for text however, because images are not composited into their background even if the background color is opaque.
This diff precomposites network images with their background color when the background is opaque, allowing them to take advantage of this performance optimization.
I've also added some logic to correctly crop the downloaded image when the resizeMode is "cover" or "contain" - previously it was only correct for "stretch".
Before:{F22437859}
After:{F22437862}
Test Plan: Run the UIExplorer "<ListView> - Paging" example with "color blended layers" enabled and observe that the images appear in green now, instead of red as they did before.
Summary:
D2052669 introduced a block for objects that had to be invalidated on the main
thread, but after the JS thread objects, but the block was being dispatched on
the JS thread.
@public
Test Plan:
I added `RCTAssertMainThread()` to the `mainThreadInvalidate` block, it was
crashing on reload, but now it should work as expected.
Summary:
The parent RCTBridge no longer tracks the JS loading since that has been handed off to the RCTBatchedBridge. To make the `loading` property accurate again, just expose the batch bridge's loading property from the parent bridge (note: I didn't make it KVO-compliant).

Summary:
Add the RCTBatchedBridge object to the notification's userInfo for consistency with RCTJavaScriptDidLoadNotification, and set the target object to `_parentBridge`.

Summary:
After the RCTBatchedBridge refactor, the `-[NSNotificationCenter addObserver]` and `[removeObserver]` calls got divided between RCTBridge and RCTBatchedBridge. This diff does two things:
- Moved `removeObserver` out of RTCBatchedBridge and into `-[RCTBridge invalidate]`
- Moved `addObserver` from `bindKeys` to `setUp`. This is so that `-[RCTBridge reload]` will re-add the observer after invalidating and removing the observer

Summary:
The RCTRootView creates a underlying RCTRootContentView that was deallocated when
the bridge modules were deallocated. That doesn't work when the bridge is held.
@public
Test Plan:
Launch Groups, put a breakpoint on `-[RCTRootContentView dealloc]`, enter and
leave a group page. It should be called now.
Summary:
Apparently British spelling is "cancelled", American is "canceled"? Picking "cancelled" for consistency with UIKit.

Summary:
This provides a way to get notified when a bridge fails to load JS, allowing apps to handle the error.
Closes https://github.com/facebook/react-native/pull/1085
Github Author: James Ide <ide@jameside.com>
Test Plan: run the UIExplorer app with the packager server not running, and verify that the notification is posted.
Summary:
When touches end or cancel, update self.state in
RCTTouchHandler to let iOS know that we are in an ended/canceled state.
This way we won't eat other touches because it still thinks we're in a
began/changed state.

Test Plan:
Scrolling in the back swipe area no longer busts gesture
recognition in Wilde.

@nicklockwood - Could I get a review of this?
Just took `RCTTextField` and ported it from `UITextField` to `UITextView` as you mentioned in another discussion, and removed any `UITextField` specific attributes.
- How do you think this should behave when there are subviews?
- Do you know how we can respond to the `UIControlEventEditingDidEndOnExit` event to respond to submit? Because `UITextView` isn't a `UIControl` we can't just use `addTarget` with `UIControlEventEditingDidEndOnExit`.
- Any other feedback?
Still going to look over the `UITextView` docs in more detail and make sure we expose all important options, and add it to the UIExplorer example, just putting this out here for feedback.
