Summary:
This prop exposes the functionality provided by Android ScrollView's setOverScrollMode method.
One interesting thing to note is that, if you were to read the Android docs, you would think that the value "always" is the default over scroll mode. However, the docs are incorrect and "always-if-content-scrolls" is actually the default value (http://stackoverflow.com/a/27116306).

Summary:
This is a followup for https://github.com/facebook/react-native/pull/12088 and implements the scrolling to end on Android natively rather than sending a large scroll offset from JS.
This turned out to be an OK amount of code, and some reduction in the amount of JavaScript. The only part I'm not particularly happy about is:
```
// ScrollView always has one child - the scrollable area
int bottom = scrollView.getChildAt(0).getHeight() + scrollView.getPaddingBottom();
```
According to multiple sources (e.g. [this SO answer](http://stackoverflow.com/questions/3609297/android-total-height-of-scrollview)) it is the way to get the total size of the scrollable area, similar to`scrollView.contentSize` on iOS but more ugly and relying on the fact the ScrollView always has a single child (hopefully this won't change in future versions of Android).
An alternative is:
```
View lastChild = scrollLayout.getChildAt(scrollLayout.getChildCount() - 1);
int bottom = lastChild.getBottom() + scrollLayout.getPadd

onEditorAction twice, once with IME_NULL and another time with the respective IME_ACTION.

<TextInput
returnKeyType='go'

Summary:
Currently, < WebView > allows you to pass JS to execute within the view. This works great, but there currently is not a way to execute JS after the page is loaded. We needed this for our app.
We noticed that the WebView had messaging support added (see #9762) . Initially, this seemed like more than enough functionality for our use case - just write a function that's injected on initial load that accepts a message with JS, and `eval()` it. However, this broke once we realized that Content Security Policy can block the use of eval on pages. The native methods iOS provide to inject JS allow you to inject JS without CSP interfering. So, we just wrapped the native methods on iOS (and later Android) and it worked for our use case. The method injectJavaScript was born.
Now, after I wrote this code, I realized that #8798 exists and hadn't been merged because of a lack of tests. I commend what was done in #8798 as it sorely solves a problem (injecting JS after the initial load) and has more features than what I'

Summary:
Android has a text API called breakStrategy for controlling how paragraphs are broken up into lines. For example, some modes support automatically hyphenating words so a word can be split across lines while others do not.
One source of complexity is that Android provides different defaults for `breakStrategy` for `TextView` vs `EditText`. `TextView`'s default is `BREAK_STRATEGY_HIGH_QUALITY` while `EditText`'s default is `BREAK_STRATEGY_SIMPLE`.
In addition to exposing `textBreakStrategy`, this change also fixes a couple of rendering glitches with `Text` and `TextInput`. `TextView` and `EditText` have different default values for `breakStrategy` and `hyphenationFrequency` than `StaticLayout`. Consequently, we were using different parameters for measuring and rendering. Whenever measuring and rendering parameters are inconsistent, it can result in visual glitches such as the text taking up too much space or being clipped.
This change fixes these inconsistencies by setting `breakStrategy` and `hyphenat

By default Android will put extra space above text to allow for upper-case accents or other ascenders. With some fonts, this can make text look slightly misaligned when centered vertically.
We have found that the effect is very noticeable with certain custom fonts on Android. On iOS the font aligns vertically as expected.
Android exposes a property `includeFontPadding` that will remove this extra padding if set to false. This PR exposes that to JS, and adds it to the documentation and UIExplorer.

Summary:
Suppose that the user is scrolled to the bottom of a ScrollView. Next, the ScrollView's content is edited such that the height of the content changes and the current scroll position is larger than the new height of the content. Consequently, the user sees a blank ScrollView. As soon as the user interacts with the ScrollView, the ScrollView will jump to its max scroll position.
This change improves this scenario by ensuring that the user is never staring at a blank ScrollView when the ScrollView has content in it. It does this by moving the ScrollView to its max scroll position when the scroll position after an edit is larger than the max scroll position of the ScrollView.
Here are some pictures to illustrate how this PR improves the scenario described above:

Summary:
On Android, if there is a small amount of space available around a text input (e.g. landscape orientation on a phone), Android may choose to have the user edit the text inside of a full screen text input mode. This behavior isn't always desirable. For example, if your app offers some UI controls for controlling the formatting of the text, you want the controls to be visible while the user is editing the text. This Android feature conflicts with that desired experience because the UI controls would be hidden while the text is being edited.
The `disableExtractUI` prop enables developers to choose whether or not Android's full screen text input editing mode is enabled. When this prop is true, Android's `IME_FLAG_NO_EXTRACT_UI` flag is passed to the `setImeOptions` method.
**Test plan (required)**

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:
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.

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.
