Summary:
Nested scrolling in scrollViews, listViews and flatLists are enabled on iOS by default, but needs to be enabled manually on Android. This PR introduces a `nestedScrollEnabled` property to ScrollViews to support nested scrolling on Android 21 and above.
Enabling nested scroll will resolve issues with coordinator layout in android and required to support a collapsing toolbar.
Tested on the test app. We are also using this property in our app currently to support scrolling behaviour required by coordinator layouts.

On iOS, when the parent Text contains the `lineHeight` style prop, and the children are also Text components they don't inherit the lineHeight prop.
This is for **iOS** only.
Create a react-native project with React Native 0.54.0 or 0.54.1 and change the app to:
```js
import React, { Component } from 'react';
import { StyleSheet, Text, View } from 'react-native';
type Props = {};
export default class App extends Component<Props> {
render() {
return (
<View style={styles.container}>
<Text style={{ fontWeight: 'bold', lineHeight: 40 }}>
<Text style={{ color: 'orange' }}>I am bold and orange, </Text>
<Text style={{ color: 'red' }}>I am bold and red, </Text>
<Text style={{ color: 'blue' }}>I am bold and blue, </Text>
<Text style={{ color: 'purple' }}>I am bold and purple, </Text>
<Text style={{ color: 'yellow' }}>I am bold and yellow, </Text>
<Text style={{ color: 'pink' }}>I am bold and pink</Text>
</Text>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
backgroundColor: 'black',
flex: 1,
justifyContent: 'center',
padding: 50,
},
});
```

Summary:
A common UI pattern for list empty states is some text/images centered inside the visible part of the list. This is pretty hard to do currently because we wrap ListEmptyComponent with an extra view with no way to style it so we cannot just use `flex: 1` to make it fill the available space.
- Added an example of ListEmptyComponent in the FlatList example in RNTester
Before (no way to make ListEmptyComponent fill the space):

Summary:
`<Image resizeMode="repeat" />` for Android, matching the iOS implementation (#7968). (Non-goal: changing the component's API for finer-grained control / feature parity with CSS - this would be nice in the future)
As requested in e.g. #14158.
Given https://github.com/facebook/fresco/issues/1575, and lacking the context to follow the specific recommendations in https://github.com/facebook/fresco/issues/1575#issuecomment-267004303, I've opted for a minimal change within RN itself.
It's likely that performance can be improved by offloading this work to Fresco in some clever way; but I'm assuming that the present naive approach is still an improvement over a userland implementation with `onLayout` and multiple `<Image>` instances.
- Picking up on a TODO note in the existing code, I implemented `MultiPostprocessor` to allow arbitrary chaining of Fresco-compatible postprocessors inside `ReactImageView`.
- Rather than extensively refactor `ImageResizeMode`, `ReactImageManager` and `ReactImageView`, I mostly preserved the existing API that maps `resizeMode` values to [`ScaleType`](http://frescolib.org/javadoc/reference/com/facebook/drawee/drawable/ScalingUtils.ScaleType.html) instances, and simply added a second mapping, to [`TileMode`](https://developer.android.com/reference/android/graphics/Shader.TileMode.html).
- To match the iOS rendering exactly for oversized images, I found that scaling with a custom `ScaleType` was required - a kind of combination of `CENTER_INSIDE` and `FIT_START` which Fresco doesn't provide - so I implemented that as `ScaleTypeStartInside`. (This is, frankly, questionable as the default behaviour on iOS to begin with - but I am aiming for parity here)
- `resizeMode="repeat"` is therefore unpacked by the view manager to the effect of:
```js
view.setScaleType(ScaleTypeStartInside.INSTANCE);
view.setTileMode(Shader.TileMode.REPEAT);
```
And the added postprocessing in the view (in case of a non-`CLAMP` tile mode) consists of waiting for layout, allocating a destination bitmap and painting the source bitmap with the requested tile mode and scale type.
Note that as in https://github.com/facebook/react-native/pull/17398#issue-285235247, I have neither updated nor tested the "Flat" UI implementation - everything compiles but I've taken [this comment](https://github.com/facebook/react-native/issues/12770#issuecomment-294052694) to mean there's no point in trying to wade through it on my own right now; I'm happy to tackle it if given some pointers.
Also, I'm happy to address any code style issues or other feedback; I'm new to this codebase and a very infrequent Android/Java coder.
Tested by enabling the relevant case in RNTester on Android.

Summary:
Don't lock out other non-iOS platforms (e.g. Windows) with an overly
specific check. This change allows this JS file to be re-used instead of copied and modified. There was one other instance of this pattern, but I'll submit it separate for easier cherry-picking.
Tested Android and iOS playground on simulators.

Summary:
The flow type for View using createReactClass was essentially `any`, allowing any Prop to be passed in, only pseudo enforced at run time via propTypes.
This diff converts View away from createReactClass and instead uses ReactNative.NativeComponent. This was previously typed as any as well which didn't buy us much. This change converts View to be an ES6 React class component to ensure proptypechecking, and exposes the methods copied from NativeMethodsMixin.

Summary:
We have a bunch of components internally that use accessibilityLabel in invalid ways.
View was originally typed as any so invalid usages weren't caught. In order to fix these we have to move forward with getting back to flow having no errors. We are weakening these types to get there and we can tighten them again later.

Summary:
We plan to migrate native components like View, Text, and Image to be typed with Flow instead of propTypes so that we can better enforce our usages.
This change makes it so that *if* propTypes are defined they must cover the native props. However, if they aren't specified, the validation doesn't occur.
Eventually, the prop validation should occur via codegen that generates an interface the native component must implement from the flow types defined in JS.
