Summary:
Adds the feature to use percentage as a value unit.
You can use the function ```YGPx(float)``` and ```YGPercent(float)``` for convenience.
I did some benchmarks:

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:
There was a bug in the view clipping logic.
Clipping works on uiview hierarchy, but I've been using `reactSuperview` to get clipping rect for my parent.
This is incorrect in a case where these two hierarchies don't match and there are some views between a view and its `reactSuperview`.
So we should really use normal `superview`. A minor complication is that `superview` is `nil` if we are clipped.
We could remember what our last `superview` was, but that's extra data we have to manage. Instead I use one clever trick to avoid doing so.
(Let me know if it makes sense based on my inline documentation.)

Summary:
React view hierarchy doesn't have to always match uiview hierarchy. Plus if we clip view we loose knowledge about view's react superview if we just use `self.superview` as react superview.
This diff fixes it by storing a strong ref to reactSuperview in an associated object.
This is needed for new view clipping implementation (see the dependent diff).

Summary:
Fixes#4740, where views would unnecessarily be retained after performing `navigator.pop()` - this was particularly problematic for big lists and memory-intensive custom views.
This fix causes no functional change: `_previousViews` are only used in the loop starting at line 564 to ensure that the JavaScript and Native navigation stacks are equivalent at all times. As we do in this fix, that loop limits itself to only the views expected to be on the React navigation stack. So overall this change makes the code logically 'more correct'.
Tested by checking that `_previousViews.count` is always equivalent to `previousReactCount` in the loop (which means we could remove the complex `MIN(... MIN(previousReactCount, _previousViews.count)` in the loop too, but I wanted to keep the diff as small as possible for now).

UIScrollView's internal logic with scroll indicator dies when bad values (e.g. NaN/Infinity) are set on the position/size.
We already guard UIManager with these checks but the RCTScrollView's underlying scrollview (RCTCustomScrollView) can get these set from other places, and we're seeing crashes in this area.

Summary:
This fixes measuring of items in the main axis of a container. Previously items were in a lot of cases measured with UNSPECIFIED instead of AT_MOST. This was to support scrolling containers. The correct way to handle scrolling containers is to instead provide them with their own overflow value to activate this behavior. This is also similar to how the web works.
This is a breaking change. Most of your layouts will continue to function as before however some of them might not. Typically this is due to having a `flex: 1` style where it is currently a no-op due to being measured with an undefined size but after this change it may collapse your component to take zero size due to the implicit `flexBasis: 0` now being correctly treated. Removing the bad `flex: 1` style or changing it to `flexGrow: 1` should solve most if not all layout issues your see after this diff.

Summary: Introduce `overflow:scroll` so that scrolling can be implemented without the current overflow:visible hackiness. Currently we use AT_MOST to measure in the cross axis but not in the main axis. This was done to enable scrolling containers where children are not constraint in the main axis by their parent. This caused problems for non-scrolling containers though as it meant that their children cannot be measured correctly in the main axis. Introducing `overflow:scroll` fixes this.

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:
iOS and css have a different way to draw borders. Decision which rendering to use considers alpha value of given color as well.
If alpha=0 -> border is invisible -> we use ios render.
That doesn't work as expected in a case where only `borderWidth` property is set.
A default black color is used when no `borderColor` is set, but alpha checking logic will test `null`. Which resolves as alpha=0.

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.

Issue we were seeing: scrollview would clip its cells when it was resized to 0 height and moved offscreen, but it wouldn't add it back when it was resized and moved back
Why this was happening: scrollview wouldn't rerun its un/clipping logic after the first run unless 1/it has 0x0 frame or 2/it has been scrolled. Neither was happening here.
Fix: run the un/clipping logic when scrollview's frame has been changed since the last clipping.
