Summary:
This fixes a bug that causes properties to keep stale values because they were not restored to their default after being removed when their value was controlled by native animated.
To fix this we restore default values in `disconnectFromView` by updating views with null values for all props that we modified previously. However this causes another issue where we lose any props that were set by the normal process because NativeAnimated operations are always executed after UIManager operatations. To fix this I added a way to hook into UIManager view updating process to be able to execute NativeAnimated operations either before or after updating native views.
In the case of disconnecting we want to do it before updating views so that it does: Value changed by native animated -> value restored to default -> (optional) value updated by normal prop.
This PR also depends on #10658.

Summary:
Moving setting `availableSize` for `RCTRootShadowView` on earlier stage allows to prevent situations where `availableSize` is not specified yet, but Yoga layout is already happening.
Because `availableSize` equals {infinity, infinity} by default (in this case), Yoga returns a lot of nodes with infinit metrics, which confises UIKit.

Summary:
A related Android PR is #11008.
Font scale was exposed through:
- The `getContentSizeMultiplier` method
- The `didUpdateContentSizeMultiplier` event
These are now deprecated. The reason is that there was already an API that exposed font scale. However, it was Android only. We now expose font scale through that API on iOS as well. Specifically:
- Font scale is now available as `PixelRatio.getFontScale()`.
- The `change` event on the `Dimensions` object now fires when font scale changes.
This change also adds support for `Dimensions.get('screen')` on iOS. Previously, only `Dimensions.get('window')` was available on iOS. The motivation is that, [according to this comment](https://github.com/facebook/react-native/pull/11008#issuecomment-275123609), we'd like to deprecate `window` dimensions in favor of `screen` dimensions in the future.
**Test plan (required)**
Verified that `PixelRatio.getFontScale()` and the `change` event work properly in a test app.

Summary:
Motivation:
* `RCTShadowView`'s `frame` property actually represents computed layout of the view. We must not use it as a setter for yoga node styles;
* Using `frame` and `setLeftTop` in existing way actually works only for view with absolute positioning, so it is super rare and special case;
* Internally, setting `frame` only make sense to `RootView`, and in that case there we always must not change `origin` we are introducing `setSize` method.
Changes:
* `[-RCTShadowView setFrame:]` was removed, `frame` property is readonly now;
* `[-RCTShadowView setLeftTop:]` was removed; no replacement provided;
* `[-RCTShadowView size]` read-write property was added;
* `[-RCTUIManager setFrame:forView:]` was deprecated, use (just introduced) `setSize:forView:` instead;
* `[-RCTUIManager setSize:forView:]` was added.
If you are still need some of removed methods, you are probably doing something wrong. Consider using `setIntrinsicContentSize`-family methods,
`setSize`-family methods, or (in the worst case) accessing `yogaNode` directly.

On certain devices (in my case, any iPad Pro model), listening to `DeviceEventEmitter.didUpdateDimensions` would call back *before* the interface change takes places (i.e. calling `Dimensions.get()` in this callback would return wrong values). Turns out that we were listening for the wrong native event.
Edit to add: now using `[RCTSharedApplication() statusBarOrientation]` to get the current orientation. Not yet sure why, but the `userInfo` provided by the notification was returning the wrong orientation *only* on the first time you rotate the device.

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.

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.

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.
