Summary:
To make React Native play nicely with our internal build infrastructure we need to properly namespace all of our header includes.
Where previously you could do `#import "RCTBridge.h"`, you must now write this as `#import <React/RCTBridge.h>`. If your xcode project still has a custom header include path, both variants will likely continue to work, but for new projects, we're defaulting the header include path to `$(BUILT_PRODUCTS_DIR)/usr/local/include`, where the React and CSSLayout targets will copy a subset of headers too. To make Xcode copy headers phase work properly, you may need to add React as an explicit dependency to your app's scheme and disable "parallelize build".

Summary:
Include CSSLayout headers in the same way as other project headers, ie `#import <CSSLayout/CSSLayout.h>` becomes `#import "CSSLayout.h"`. CSSLayout is not a framework or system dependency, so shouldn't (AFAIK) be included with angle brackets. Doing so breaks framework builds, such as when RN is used as a pod in a swift project.
In combination with https://github.com/facebook/css-layout/pull/217 this fixes https://github.com/facebook/react-native/issues/9014 (specifically swift cocoapods projects). There is then no need for a separate CSSLayout pod subspec.
Tests run on the RN project in isolation (with changes inside `CSSLayout` itself also applied) and against a dummy swift project with RN included as a pod.
NB: This effectively reverts https://github.com/facebook/react-native/pull/9015 and may break non-swift cocoapods projects unless https://github.com/facebook/css-layout/pull/217 is merged and synced first.
Update: As discussed with alloy and emilsjolander, wrap these imports in a preprocess

Summary:
Sometimes is handy to check if a React node is a descendant of another node or not. For instance, I want to check if the focused `TextInput` is descendant of an specific `ScrollView`:
```js
const currentlyFocusedField = TextInput.State.currentlyFocusedField()
UIManager.viewIsAncestorOf(
currentlyFocusedField,
this.getInnerViewNode(),
(isAncestor) => {
if (isAncestor) {
console.log('The focused field is a descendant of this ScrollView!')
}
}
)
```
This function uses the same strategy as the `measureLayout` method to check if one node is an ancestor of other node. As the `measureLayout` method, this is performed outside the main thread.
By now I've only implemented the iOS version and its tests, but if this function is going to be merged I'll implement the Android version too. I have objc experience but no Java or Android, so I prefer to validate this functionality before jumping into developing the Android part.

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.

As per https://twitter.com/olebegemann/status/738656134731599872, our use of "main thread" to mean "main queue" seems to be unsafe.
This diff replaces the `NSThread.isMainQueue` checks with dispatch_get_specific(), which is the recommended approach.
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.

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.
This commit also contains a change in `RCTShadowText.m`
`_setParagraphStyleOnAttributedString:heightOfTallestSubview:`. It now only sets
`lineHeight`, `textAlign`, and `writingDirection` when they've actua

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: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.
**Test plan**
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.
I also plan to work on improving the doc for LayoutAnimation as well as making this PR for android too.

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: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.
