Summary:
Potential breaking change: The signature of ReactShadowNode's onBeforeLayout method was changed
- Before: public void onBeforeLayout()
- After: public void onBeforeLayout(NativeViewHierarchyOptimizer nativeViewHierarchyOptimizer)
Implements same feature as this iOS PR: https://github.com/facebook/react-native/pull/7304
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 via FrescoBasedReactTextInlineImageSpan. To get support for nesting views within Text, we create one special kind of span per inline view. This span is called TextInlineViewPlaceholderSpan. It is the same size as the inline view. Its job is just to occupy space -- it doesn't render any visual. After the text is rendered, we query the Android Layout object associated with the TextView to find out where it has positioned each TextInlineViewPlaceholderSpan. We then position the views to be at those locations.
One tricky aspect of the implementation is that the Text component needs to be able to render native children (the inline views) but the Android TextView cannot have children. This is solved by having the native parent of the ReactTextView also host the inline views. Implementation-wise, this was accomplished by extending the NativeViewHierarchyOptimizer to handle this case. The optimizer now handles these cases:
- Node is not in the native tree. An ancestor must host its children.
- Node is in the native tree and it can host its own children.
- (new) Node is in the native tree but it cannot host its own children. An ancestor must host both this node and its children.
I added the `onInlineViewLayout` event which is useful for writing tests for verifying that the inline views are positioned properly.
Limitation: Clipping
----------
If Text's height/width is small such that an inline view doesn't completely fit, the inline view may still be fully visible due to hoisting (the inline view isn't actually parented to the Text which has the limited size. It is parented to an ancestor which may have a different clipping rectangle.). Prior to this change, layout-only views had a similar limitation.

Summary:
[Android] [Fixed] - LayoutAnimations cause invalid view operations
The dating team has found a consistent repro where following an order of steps will get you the following exception:
https://lookaside.facebook.com/intern/pixelcloudnew/asset/?id=2113362972287761
The exception is due to the fact that the following operation
`delete child tag 17 from parent tag 481 which is located at index 2`
cannot be performed because parent tag 481 only has 2 children.. and they also happen to not have the tag 17 as a child. Somehow the operations and the tree they act upon are out of sync.
RN receives operations from React via the native module `UIManagerModule`. The operations use tags (an identifier for a view) and indices to determine what view is updated. These operations (grouped together as a batch) are then passed to the UI thread where we perform them on the platform views.
LayoutAnimations are implemented per batch in RN. When LayoutAnimations are on, qualified view updates are animated. Because the delete operation is animated, RN doesn't remove the view from the platform view hierarchy immediately but asynchronously -- after the animation is complete. This is problematic for other view operations that rely on an index on where to insert or delete a view because during the creation of those operations, it was assumed all prior operations were performed synchronously.
This is what was occurring in the repro and there were silent view errors occurring before the exception was thrown.
This diff proposes a solution to track all pending delete operations across operations.
We introduce a map that is keyed on view tags and has a value of a sparse array that represents child index -> count of views that are pending deletion.
`{11: [0=1], 481: [2=1]}` where this would be interpreted as for index 0 under view tag 11, there is one async view deletion that has not completed and under tag 481 there is one async view deletion at index 2.
We use the map to adjust indices on add / delete operations. We also update the count when the deletion animation is complete and remove the tag from the map when it is deleted.
Regarding worst case sizing of the map => O(# of platform views rendered)

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:
This PR was split from commits originally in #8619. /cc dmmiller
These refactorings to the HierarchyOptimizer are in preparation for implementing support for inline views in #8619.
**Refactoring 1: Collapse add*LayoutOnlyNodeToLayoutOnlyNode**
addLayoutOnlyNodeToLayoutOnlyNode and addNonLayoutOnlyNodeToLayoutOnlyNode
had nearly identical implementations. They both walk thru the ancestors
looking for a nonlayout-only node and adjusting the passed in index at each
step. This introduces a new function, walkUpUntilNonLayoutOnly, which
takes care of that responsibility. This simplifies addNodeToNode
because it can now consider the type of the parent and the type of
the child independently.
**Refactoring 2: Extract addGrandchildren**
Pull out addLayoutOnlyNode's logic into a helper called
addGrandchildren. We will need to call this method in
another place later.
**Test plan (required)**
This change was tested with UIExplorer and a small test app and it's being used in my team's app.

Summary: public NativeViewHierarchyManager.createView() takes int rootViewTag which is only used to resolve ThemedReactContext, but we already have it resolved before we enqueueCreateView, so we can just pass it directly. This makes mRootViewsContext tag -> to ThemedReactContext mapping unnecessary in NativeViewHierarchyManager. Makes the class simpler.

Summary: public
Native view recycling implementation based on limited pools of views.
In this diff I introduced new UIManager method: dropViews. Instead of removing views from tag->view maps when they are detached we keep them there until we get a call to dropViews with the appropriate tag. JS may keep a pool of object and selectively decide not to enqueue drop for certain views. Then instead of removing those views it may decide to reuse tag that has been previously allocated for a view that is no longer in use.
Special handling is required for layout-only nodes as they only can transition from layout-only to non-layout-only (reverse transition hasn't been implemented). Because of that we'd loose benefits of view flattening if we decide to recycle existing non-layout-only view as a layout-only one.
This diff provides only a simple and manual method for configuring pools by calling `ReactNativeViewPool.configure` with a dict from native view name to the view count. Note that we may not want recycle all the views (e.g. when we render mapview we don't want to keep it in memory after it's detached)
