Summary:
Expose aspectRatio style prop from css-layout to React Native.
This means the following will now work:
<View style={{backgroundColor: 'blue', aspectRatio: 1}}/>

Summary:
Virtual shadow nodes (e.g. text) don't use CSSNodes so we don't need to create them. This shows large savings in CSSNodes allocated, depending on the app.
This could be breaking if:
- You have virtual nodes that still set and get CSS properties. The setters now no-op for virtual nodes (I unfortunately couldn't remove them completely -- see the comment on LayoutShadowNode), but the getters will NPE. If you see these NPE's, you should almost definitely be using your own datastructure instead of a CSSNode as virtual nodes will not participate in the layout process (and the CSSNode is then behaving just as a POJO for you).
I do not anticipate this to be breaking for anyone, but am including breaking in the commit message since this is a change in API contract.

Summary: Adds a pool to recycle CSSNodes within UIManager. A follow-up diff will hook this up to a memory pressure listener to drop the pool on memory pressure.

Summary:
Moves from CSSNodeDEPRECATED to CSSNode. This has shown to be a huge performance win for layout time within FB.
This is BREAKING because CSSNode contains bug fixes that were not migrated to CSSNodeDEPRECATED which may change the way your layout appears. The most common of these by far involves `flex: 1`.
Previously, developers had to put `flex: 1` in many places it didn't belong in order to work around a bug in css-layout. Now `flex: 1` is treated properly and, unfortunately, this means that your layout may no longer look correct. Specifically, you may see that your layout looks collapsed, or children don't render. The fix is to simply remove `flex: 1` from those containers.

Summary:
This diff makes it so ReactShadowNode holds a CSSNode instead of extending one. This will enable us to pool and re-use CSSNodes and will allow us to keep from breaking the CSSNode api assumption that nodes that have measure functions don't have children (right now, text nodes have measure functions, but they also have raw text children).
BREAKING
This diff makes ReactShadowNode no longer extend CSSNodeDEPRECATED. If you have code that depended on that, e.g. via instanceof checks, that will no longer work as expected. Subclasses that override getChildAt/addChildAt/etc will need to update your method signatures. There should be no runtime behavior changes.

Summary:
This adds support for sticky headers on Android. The implementation if based primarily on the iOS one (https://github.com/facebook/react-native/blob/master/React/Views/RCTScrollView.m#L272) and adds some stuff that was missing to be able to handle z-index, view clipping, view hierarchy optimization and touch handling properly.
Some notable changes:
- Add `ChildDrawingOrderDelegate` interface to allow changing the `ViewGroup` drawing order using `ViewGroup#getChildDrawingOrder`. This is used to change the content view drawing order to make sure headers are drawn over the other cells. Right now I'm only reversing the drawing order as drawing only the header views last added a lot of complexity especially because of view clipping and I don't think it should cause issues.
- Add `collapsableChildren` prop that works like `collapsable` but applies to every child of the view. This is needed to be able to reference sticky headers by their indices otherwise some subviews can get optimized out and break indexes.

Summary:
The annotation processor finds subclasses of ViewManager and ShadowNode and generates classes that can both provide a mapping of property names to their type as well as a way of setting these properties.
This avoids having to do reflection to find the properties.
The annotation processor is currently not working when building with Gradle.

This is an early release and there are several things that are known
not to work if you're porting your iOS app to Android.
See the Known Issues guide on the website.
We will work with the community to reach platform parity with iOS.
