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:
/cc janicduplessis mdvacca
This addresses the same issue as #18830 which was reverted since it didn’t handle `removeClippedSubviews` properly.
When subview clipping is on, ReactViewGroup keeps track of its own children directly and accounts for the offset introduced by clipped views when calling ViewGroup methods that modify children.
Instead of accounting for just clipped children (views with no parent), it should account for any children that aren’t in the ViewGroup which also includes children that are being transitioned. If you look at the ViewGroup source code, [it explicitly retains the view parent until the transition finishes](https://github.com/aosp-mirror/platform_frameworks_base/blob/oreo-release/core/java/android/view/ViewGroup.java#L5034-L5036) which caused the `getParent()` checks to pass, even though those views should be ignored. I added a new `isChildInViewGroup` method that handles both clipped and transitioning views to fix this.
I reproduced the [earlier crash](https://github.com/facebook/react-native/pull/18830#issuecomment-382798628) by enabling clipping in [this test app](https://github.com/facebook/react-native/pull/18830#pullrequestreview-111758886) and adding a “clear views” button that resets the state to an empty items array with an animation.

Summary:
Fixes issue #11828 that causes layout animations for removed views to
remove some adjacent views as well. This happens because the animated
views are still present in the ViewGroup, which throws off subsequent
operations that rely on view indices having updated.
This issue was addressed in #11962, which was closed in favour of a more
reliable solution that addresses the issue globally since it’s difficult
to account for animated views everywhere. janicduplessis [recommended][0]
handling the issue through ViewManager.
Since API 11, Android provides `ViewGroup#startViewTransition(View)`
that can be used to keep child views visible even if they have been
removed from the group. ViewGroup keeps an array of these views, which
is only used for drawing. Methods such as `ViewGroup#getChildCount()`
and `ViewGroup#getChildAt(int)` will ignore them.
I believe relying on these framework methods within ViewManager is the
most reliable way to solve this issue because it also works if callers
ignore ViewManager and reach into the native view indices and counts
directly.

I wrote a minimal test app that you can find here:
<https://gist.github.com/lnikkila/87f3825442a5773f17ead433a810d53f>
The expected result is that the red and green squares disappear, a blue
one appears, and the black one stays in place. iOS has this behaviour,
but Android removes the black square as well.
We can see the bug with some breakpoint logging.
Without LayoutAnimation:
```
NativeViewHierarchyOptimizer: Removing node from parent with tag 2 at index 0
NativeViewHierarchyOptimizer: Removing node from parent with tag 4 at index 1
NativeViewHierarchyManager: Removing indices [0] with tags [2]
RootViewManager: Removing child view at index 0 with tag 2
NativeViewHierarchyManager: Removing indices [1] with tags [4]
RootViewManager: Removing child view at index 1 with tag 4
```
With LayoutAnimation tag 3 gets removed when it shouldn’t be:
```
NativeViewHierarchyOptimizer: Removing node from parent with tag 2 at index 0
NativeViewHierarchyOptimizer: Removing node from parent with tag 4 at index 1
NativeViewHierarchyManager: Removing indices [0] with tags [2]
NativeViewHierarchyManager: Removing indices [1] with tags [4]
-> RootViewManager: Removing child view at index 1 with tag 3
RootViewManager: Removing child view at index 2 with tag 4
(Animation listener kicks in here)
RootViewManager: Removing child view at index 1 with tag 2
```

Summary:
Use `getChildDrawingOrder` instead of reordering views. The old implementation didn't work properly when `removeClippedSubviews` was enabled and this one should have better performance since we don't play with the view hierarchy at all.
This fixes weird bugs with sticky headers in `SectionList` and allows removing the hack that disabled `removeClippedSubviews` when using sticky section headers.
**Test plan**
Tested using the SectionList and ListViewPaging examples that use sticky headers which uses z-index.

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.
