Summary:
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)**
Verified `disableExtractUI` works for both `true` and `false` values in a test app.

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.

Summary:
This changes modal behavior to resize when the keyboard appears/disappears.
Previously, the modal would not react in any way, or it would pan above to bring the
TextInput into view. Resizing is the correct behavior for android.
This is not trivial, as in, setting the flag, because of the combination of
react native laying out all views and the system reacting to the keyboard
appearance in a weird way. Namely:
- if `windowTranslucentStatus` is not set, the system will just call
`onSizeChanged` on the dialog's content view, and everything works nicely
- with `windowTranslucentStatus` set, the system will consider the dialog as a
full screen view that doesn't resize. In order for it to resize, the base
view of the layout needs to have
`setFitsSystemWindows(true)` called on it. This is needed, so that the system
can call layout on that base view with the new value of `paddingBottom` that
coincides with the height of the keyboard. Neat.
We fix this by wrapping our existing content view (mHostView) in a simple
FrameLayout that has `setFitsSystemWindows` set. That way, `mHostView` will have
`onSizeChanged` called on itself with the correct new size of the dialog.
This has the fortunate consequence of our layout now also getting `paddingTop` as the size of the
status bar, which means that we can remove the JS `top` hack in Modal, which
was necessary for no view getting drawn under the status bar.
This behavior is set as default, since that is the default correct Android behavior.

Summary:
`ReactSwipeRefreshLayout` extends `SwipeRefreshLayout` which does not play nice with Android's touch handling system.
There are two problems:
1. `SwipeRefreshLayout` overrides and swallows `requestDisallowInterceptTouchEvent`, which means that Views underneath the `SwipeRefreshLayout` will not interact correctly with parent Views of
`SwipeRefreshLayout`. We've seen this in practice by H-ScrollViews having their touches intercepted by an enclosing ViewPager. This is fixed by passing `requestDisallowInterceptTouchEvent` up to the parents of `SwipeRefreshLayout`.
2. `SwipeRefreshLayout` overrides `onInterceptTouchEvent` and never calls `super.onInterceptTouchEvent`, therefore ignoring the value of `disallowIntercept`. That means that it will intercept some touches when it
shouldn't. One such case is again the H-ScrollView, which should receive all horizontal scrolls and stop `SwipeRefreshLayout` from intercepting any touch events after scrolling. Currently, after the H-ScrollView starts scrolling, it is still possible to get the `SwipeRefreshLayout` to detect and emit refresh events. This is fixed by checking and blocking on horizontal scrolls.

Summary:
In some cases, the size of the content view changes before we add views to the
Modal. That means that the size of that view will not be set through the
`onSizeChanged` method. This can result in some apps apparently freezing,
since the dialog is created, but there are no actual views in it.
For that reason, we still need the ModalHostShadowNode to set the size of the
initial view, so that by the time the view gets added it already has the correct
size.
There's a new helper class so that we can reuse the modal size computation.

Summary:
The issue here is that on some devices (ie. Nexus 5X), under certain
circumstances, the text gets trimmed. A simple example is P56651885, where the
text is at the end of the line and some padding is set. Digging further with
P56659346, I found that only the paddings that have integer pixel values work
correctly: these are the values P56656483, and this is the screenshot of that
test: {F63510378}.
It turns out that when we set the padding directly on the TextView, we have to
convert from float to int, and use `ceil` in the process. We lose some precision
here, since the csslayout will use the float values to compute the layout of the
views. The ideal solution would be to just set the float values on the TextView,
but since we can't do that, we should avoid using `ceil` instead of `floor`
since it can have bad side-effects in some scenarios.
Going way back to D1881202 and D1710471, we started using `ceil` because that
is how android handles non-integer
density ratios: "This figure is the factor by which you should multiply the dp
units on order to get the actual pixel count for the current screen. (Then add
0.5f to round the figure up to the nearest whole number, when converting to an
integer.)", see https://developer.android.com/guide/practices/screens_support.html.

Summary:
This automatically changes the size of the modal by listening to dialog size changes and propagating
those changes through UIManager.
In detail: I've looked into three ways of doing this:
1. Send `onSizeChanged` events/info from the View to the CSSNode directly. This is kinda hacky because you would need to hold a reference to the CSSNode somewhere, either in the View or in the ViewManager. But then you'll have to take care of the lifecycle of the CSSNode, so that you don't update it after it has been dismissed. Not great.
2. The version we went for, is to just update the size of the corresponding CSSNode in the same way we do it for root nodes: we inform the UIManager that the size of the root node has changed, and it will propagate that change, triggering a `dispatchViewUpdates` if none is underway, so that the layout is updated.
3. The other solution we thought of is to treat the Modal as a root view. This would mean rendering an application with the tag of the Modal as the root of the application. That tag would be received by calling some method into UIManager and ReactModalHostManager to create a new RootView, create a Dialog and plop the root view in it. The idea was to maintain the JS API that we now have, but make the implementation more correct (ie. since both RootView and the Modal must deal with touch handling), and could have other benefits (ie. no hacks necessary for making the inspector work on top of modals). However, the change is not trivial and I don't know just how much code would have to be changed to make this work correctly. We might revisit this at a later stage, after we've done more work on having several root views at the same time in the app.
