Summary:
Fix a bug that happens when views are added and removed in the same manageChildren block with a delete animation. What happens is that the inserted view is not inserted at the proper index if the deleted view index is smaller than the inserted one. This is because the view is not immediately removed from the subviews array so we need to offset the insert index for each view that is going to be deleted with an animation and is before the inserted view.
To do this I separated `_removeChildren` into 2 different functions, one for animated delete and one for normal delete. The animated one returns an array of `RCTComponent` that are going to be animated. We can then use this array to offset the insert index.
**Test plan (required)**
Tested that this fixed the bug in an app where I noticed it, also tested the UIExplorer example to make sure LayoutAnimations still worked properly.

Summary:
This diff implement the CSS z-index for React Native iOS views. We've had numerous pull request for this feature, but they've all attempted to use the `layer.zPosition` property, which is problematic for two reasons:
1. zPosition only affects rendering order, not event processing order. Views with a higher zPosition will appear in front of others in the hierarchy, but won't be the first to receive touch events, and may be blocked by views that are visually behind them.
2. when using a perspective transform matrix, views with a nonzero zPosition will be rendered in a different position due to parallax, which probably isn't desirable.
See https://github.com/facebook/react-native/pull/7825 for further discussion of this problem.
So instead of using `layer.zPosition`, I've implemented this by actually adjusting the order of the subviews within their parent based on the zIndex. This can't be done on the JS side because it would affect layout, which is order-dependent, so I'm doing it inside the view itself.
It works as follows:
1. The `reactSubviews` array is set, whose order matches the order of the JS components and shadowView components, as specified by the UIManager.
2. `didUpdateReactSubviews` is called, which in turn calls `sortedSubviews` (which lazily generates a sorted array of `reactSubviews` by zIndex) and inserts the result into the view.
3. If a subview is added or removed, or the zIndex of any subview is changed, the previous `sortedSubviews` array is cleared and `didUpdateReactSubviews` is called again.
To demonstrate it working, I've modified the UIExplorer example from https://github.com/facebook/react-native/pull/7825

Summary:
This diff refactors the view update process into two stages:
1. The `reactSubviews` array is set, whose order matches the order of the JS components and shadowView components, as specified by the UIManager.
2. The `didUpdateReactSubviews` method is called, which actually inserts the reactSubviews into the view hierarchy.
This simplifies a lot of the hacks we had for special-case treatment of subviews: In many cases we don't want to actually insert `reactSubviews` into the parentView, and we had a bunch of component-specific solutions for that (typically overriding all of the reactSubviews methods to store views in an array). Now, we can simply override the `didUpdateReactSubviews` method for those views to do nothing, or do something different.

I've also replaced all use of "MainThread" terminology with "MainQueue", and taken the opportunity to deprecate the "sync" param of `RCTExecuteOnMainThread()`, which, while we do still use it in a few places, is incredibly unsafe and shouldn't be encouraged.

Added a button to the iOS Red Box to enable copying of the error and stack trace to the clipboard to make it easier to paste the error and stack into bug reports or other text windows. Clicking the Copy button on the bottom of the RedBox screen or pressing Cmd-Option-C keyboard shortcut in the simulator will copy the full stack trace as text to the iOS pasteboard and when in the simulator you can then hit Command-C to get the text to the Mac's pasteboard for pasting in your favorite reporting/tracking app.
No tests for this change - I don't see any tests to extend for the RCTRedBoxWindow class. No impact on APIs or core React Native functionality. I validated it by running test React Native apps with red box errors and both hitting the copy button or using the command key shortcut in the emulator to get the text of the stack to the iOS pasteboard.

Summary:
Previously, only Text and Image could be nested within Text. Now, any
view can be nested within Text. One restriction of this feature is
that developers must give inline views a width and a height via
the style prop.
Previously, inline Images were supported by using iOS's built-in support
for rendering images with an NSAttributedString via NSTextAttachment.
However, NSAttributedString doesn't support rendering arbitrary views.
This change adds support for nesting views within Text by creating one
NSTextAttachment per inline view. The NSTextAttachments act as placeholders.
They are set to be the size of the corresponding view. After the text is
laid out, we query the text system to find out where it has positioned each
NSTextAttachment. We then position the views to be at those locations.

Summary:
The `EmitterSubscription.remove()` method was previously calling `this.subscriber.removeSubscription(this)` directly, bypassing the mechanism in `NativeEventEmitter` that keeps track of the number of subscriptions.
This meant that native event modules (subclasses of `RCTEventEmitter`) would keep sending events even after all the listeners had been removed. This wasn't a huge overhead, since these modules are singletons and only send one message over the bridge per event, regardless of the number of listeners, but it's still undesirable.
This fixes the problem by routing the `EmitterSubscription.remove()` method through the `EventEmitter` so that `NativeEventEmitter` can apply the additional native calls.
I've also improved the architecture so that each `NativeEventEmitter` uses its own `EventEmitter`, but they currently all still share the same `EventSubscriptionVendor` so that legacy code which registers events via `RCTDeviceEventEmitter` still works.

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:
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: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:

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.

Summary:If you're working on an app that needs to support landscape, reloading the app causes the iPhone simulator to reset its orientation to portrait every time the `RCTDevLoadingView` shows up. This is because it sets the root VC to `RCTModalHostViewController`, which currently supports only portrait orientations on iPhone. Changing the root view to a vanilla `UIViewController` fixes the issue.
**Steps to Reproduce**
1. Create a blank RN project: `react-native init RNTest`
2. Open it up and run it.
3. Rotate to landscape `Cmd+Right Arrow`.
4. Reload by pressing `Cmd+R`.
**Expected**
The simulator stays in landscape mode.

The simulator goes back to portrait.

Summary:Because the source of truth for backgroundColor is the shadow view, it's possible for the default RCTView backgroundColor to get overwritten by the current shadowView backgroundColor when the view is first created. This overridden value will then be used as the default whenever the background color is reset, which may not be be appropriate for other components that use RCTView.
This diff fixes the bug by ensuring that the view props (and therefore the default color) are set *before* the background color is propagated from the shadowView.
