Summary:
On iPad we may get two touch cancel events in direct succession. They would have the same coalescing key, which would result in unsuccesful attempt to coalesce them.
This diff fixes it by making sure two cancel events cannot have the same coalescing key.
(An alternative fix would be implementing coalescing logic for cancel events, but that sounds more complicated. It would be neccessary if there is a legit scenario where big number of cancel events are emitted in succesion.)

Summary:
This is a solution for the problem I raised in https://www.facebook.com/groups/react.native.community/permalink/768218933313687/
I've added a new native base class, `RCTEventEmitter` as well as an equivalent JS class/module `NativeEventEmitter` (RCTEventEmitter.js and EventEmitter.js were taken already).
Instead of arbitrary modules sending events via `bridge.eventDispatcher`, the idea is that any module that sends events should now subclass `RCTEventEmitter`, and provide an equivalent JS module that subclasses `NativeEventEmitter`.
JS code that wants to observe the events should now observe it via the specific JS module rather than via `RCTDeviceEventEmitter` directly. e.g. to observer a keyboard event, instead of writing:
const RCTDeviceEventEmitter = require('RCTDeviceEventEmitter');
RCTDeviceEventEmitter.addListener('keyboardWillShow', (event) => { ... });
You'd now write:
const Keyboard = require('Keyboard');
Keyboard.addListener('keyboardWillShow', (event) => { ... });
Within a component, you can also use the `Subscribable.Mixin` as you would previously, but instead of:
this.addListenerOn(RCTDeviceEventEmitter, 'keyboardWillShow', ...);
Write:
this.addListenerOn(Keyboard, 'keyboardWillShow', ...);
This approach allows the native `RCTKeyboardObserver` module to be created lazily the first time a listener is added, and to stop sending events when the last listener is removed. It also allows us to validate that the event strings being observed and omitted match the supported events for that module.
As a proof-of-concept, I've converted the `RCTStatusBarManager` and `RCTKeyboardObserver` modules to use the new system. I'll convert the rest in a follow up diff.
For now, the new `NativeEventEmitter` JS module wraps the `RCTDeviceEventEmitter` JS module, and just uses the native `RCTEventEmitter` module for bookkeeping. This allows for full backwards compatibility (code that is observing the event via `RCTDeviceEventEmitter` instead of the specific module will still work as expected, albeit with a warning). Once all legacy calls have been removed, this could be refactored to something more elegant internally, whilst maintaining the same public interface.
Note: currently, all device events still share a single global namespace, since they're really all registered on the same emitter instance internally. We should move away from that as soon as possible because it's not intuitive and will likely lead to strange bugs if people add generic events such as "onChange" or "onError" to their modules (which is common practice for components, where it's not a problem).

Summary:
Previously we had an issue where we would clip visible views during an animation, like swiping back a VC.
The root cause was mismatch between a view's frame and what is visible on screen. This happens because during an animation the frame (and other properties) of the animated view has final values, even that it's not yet rendered at that position.
This diff fixes this issue by not looking for a clippingView above the react root view, since the animation for VC transitions happens at view higher above the root view.

Summary:
Previously, the back swipe navigation gesture would be enabled when the navigation bar is shown and disabled when the navigation bar is hidden.
This change enables developers to control the back swipe gesture independently of the visibility of the navigation bar. An example use case would be that an app wants to render a custom navigation bar so it sets `navigationBarHidden` to true and it wants to enable the back swipe gesture so it sets `interactivePopGestureEnabled` to true.
**Test plan (required)**
- Created a test app to verify setting `interactivePopGestureEnabled` to `true` and `false` with the navigation bar both hidden and shown.
- Verified prop works in a larger app.

Summary:
Modules which call JS methods directly, or use `sendDeviceEventWithName:`, can trigger effects in JS without ever being referenced from the JS code. This breaks some assumptions in my earlier diff about when modules can be lazily loaded.
Pending a better solution, I've put explicit `init` methods in these modules to ensure they are eagerly initialized (the downside to this is that they'll still be initialized even if they are never used).

Summary:
Previously, if a module implemented `setBridge:` we assumed that it needs to be initialised on the main thread. This assumption was not really warranted however, and it was a barrier to deferring module initialization.
This diff tweaks the rules so that only modules that override `init` or `constantsToExport**` are assumed to require main thread initialization, and others can be created lazily when they are first used.
WARNING: this will be a breaking change to any 3rd party modules that are assuming `setBridge:` is called on the main thread. Those modules should be rewritten to move any code that requires the main thread into `init` or `constantsToExport` instead.
`**` We will also be examining whether `constantsToExport` can be done lazily, but for now any module that uses it will still be created eagerly when the bridge starts up.

Summary:
transformMatrix only worked on iOS and there is an equivalent API that (mostly)
works cross platform.
decomposedMatrix could technically be passed on Android but it wasn't document and explicitly flagged as not working.
My goal is to deprecate both uses and then the only supported API is the `transform: [{ matrix: ... }]` form.
The only difference is that on Android the matrix gets decomposed.
Currently there is some special cased magic that renames transform -> transformMatrix or decomposedMatrix depending on platform.
https://github.com/facebook/react/blob/master/src/renderers/native/ReactNative/ReactNativeAttributePayload.js#L50
Therefore I'm adding an alias for both native platforms called just "transform".
Next I'll swap over the JS to always target the name "transform". The only difference is how the value is marshalled over the bridge in processTransform.
To do this, I have to clean up a few callers. Mostly that's just swapping to the new API.
For buildInterpolator this is a bit trickier but this fixes it for all our use cases (which is only the Navigator in AdsManager).

Summary:
Now that we support initializing the bridge off the main thread, some of the assumptions in the bridge setup process are no longer safe.
In particular we were assuming that the JS executor and injected modules could always be synchronously initialized within bridge init, but that is only safe if those modules don't need to be set up on the main thread.
The setup for those modules was sync-dispatching to the main thread if bridge init happened on a background thread, and this lead to a deadlock under certain circumstances.

Summary: Creating a view instance just to get the default view size is quite expensive, and affects startup time for the bridge as it must be done on the main thread.

Summary:This adds support for delete view animations in LayoutAnimation for iOS. It supports the same properties as the create animation (alpha, scale).
This allows making simple animations when removing a view which is normally hard to do in React since we need to not remove the view node immediately.

Tested add/removing views in the UIExample explorer with and without setting a LayoutAnimation. Also tested that the completion callback still works properly. Tested that user interation during the animation is properly disabled.

Summary:**Motivation:** In my app, I'm using a WebView that loads content from my mobile site. What I want to do is when a user presses a link on the loaded page, I want to stop the WebView's request, hijack the URL and open the URL in a new WebView, pushed to the top of the navigator stack. To me, this gives the overall app a more native feel, instead of implementing a rudimentary navbar on the main WebView to go back.
**Attempted Workarounds:** I've attempted to get similar functionality by capturing the onNavigationStateChange event in the WebView, and then within calling goBack + pushing the new view to the navigator stack. From a functionality standpoint, this works. However, from a UI standpoint, the user can clearly see the webview change states to a new page + go back before having the new view pushed on top of their nav stack.

Summary:Hey,
I have been going through some UIAlert related issues in the repo trying to fix them, and one of the steps to start reproducing them was to put `Alert.alert()` call right inside `componentDidMount`.
However, I've started noticing strange bugs as long as I didn't set 1second timeout.
Started digging in deeper, and I've noticed the `UIAlert` gets attached to the `RCTWindow()` mainViewController.
However - since RCTDevLoadingView adds a `keyWindow`, that is the window that will be returned at the time of the call and the window `UIAlert` will be attached to.
To visualise that better - you can take a look at these two frames when app is being loaded:

Which is a small spinner in case of RelayContainer. So rarely we would end up with cut off view like this:
{F60650629}
This diff fixes this behavior by wrapping the content in another view. That makes the modal's wrapping VC's view resize just once when it's initially created. (Resize for the wrapping VC's view happened previously when the modal's content resized, which got us in the bad state.)

Summary:To use a ScrollView and RefreshControl with a translucent navigation bar you have to set the top inset to the height of that bar, allowing the content to scroll underneath. After changes to RCTRefreshControl in **v0.22**, `endRefreshing` always animates the offset to 0, hiding content behind the navigation bar. What you'd expect on iOS is for it to return to the bottom of the bar.
**Test plan**
To see this in action, refer to the UIExplorerApp. In RefreshControlExample.js if you set the ScrollView's `contentInset={{top: 100}}` you'll see the refresh control UI is where you'd expect, and after refresh the list returns to the correct position.

Summary:All UIManager operations that affect the view hierarchy are executed via the `addUIBlock:` method, which queues them up to be executed after layout has been completed on the shadow queue.
One of the most expensive view operations is view creation, but since this doesn't actually depend on layout, there's no reason to delay it until the shadow operations have finished.
This diff modifies the `createView` method to dispatch view creation directly to the main thread instead of adding it to the UIBlock queue. This seems to result a measurable improvement in TTI.
