Summary:
This PR exposes the `onScrollToTop` event on iOS using the same event-forwarding infrastructure as other ScrollView events. (As such, its `nativeEvent` object reflects the same fields as other ScrollView events.)
Motivation:
----------
If your app is only interested in knowing the position of a ScrollView after a scroll has completed, it can use `onScrollEndDrag` and `onMomentumScrollEnd` to inspect the `contentOffset` after a drag-initiated scroll has finished. (This is much less expensive than observing the `onScroll` event if you only want to know the end position.) However, neither of these `End` events fire if the ScrollView is scrolled to the top by tapping the status bar.
By exposing `onScrollToTop`, it is now possible for an app to cheaply know when such a scroll has completed.

Summary: Added `snapToStart` and `snapToEnd` props to ScrollView which work together with `snapToOffsets` and determine whether the beginning and end of the list automatically count as snap offsets or not. If not, the list is allowed to free-scroll between its start/end and the first/last snap offset.

Summary: This diff implements the HorizontalScrollView component for Android Fabric C++, as part of this diff I also re-named the components AndroidHorizontalScrollContentView for RCTAndroidHorizontalScrollContentView and AndroidHorizontalScrollView for RCTAndroidHorizontalScrollView. This might sound against our plan of removing the RCT preffix, but it is to make it simpler to map components between current implementation of RN and Fabric (otherwise we don't know when to add the RCT preffix in Android side to find the right View Manager), later we can just remove the preffix from C++, Android, iOS and JS.

We're unifying on flow types, and propTypes require non-trivial resources to initialize in aggregate.
Some open source code might depend on extracting ScrollView.propTypes which will now fail. To fix, simplly remove these dependencies and use flow or typescript for verifying correct prop usage instead.

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.

- Make the prop a dictionary for more configuration options
- Rename `maintainPositionAtOrBeyondIndex` -> `maintainVisibleContentPosition` + `minIndexForVisible`

Given the async native of RN JS and background layout, there is no way to trigger the scrollTo from JS without risking a delay, so we add the feature in native code.

Summary:
== Problem / Background ==
Most lists paginate in a single direction (standard infinite list), but some paginate in both directions. Most common example is a chat thread where new messages show up on the bottom, and old content can be loaded by scrolling up. Comment threads are another example.
Right now, adding content to the bottom of a scroll view is smooth - the content doesn't jump. But when adding to the top of the scrollview, the content gets pushed down, which is jarring (note this may appear reversed because of inverting the list which is common for chat applications).
== Approach ==
The basic idea is simple - we set a flag in JS, then for every uimanager transaction, we record which is the first eligible and visible view in the ScrollView, and compare it's new origin to the old one. If it has changed, we update the contentOffset of the ScrollView to compensate.
This is done by observing `willPerformMounting` directly (only from scrollviews that have this new property set), and then observing the prev state with prependUIBlock and making the update synchronously in addUIBlock to avoid any flicker.
There is also a way to skip views that we don't care about, like a spinner at the top of the view that we don't want to stay in place - we actually want it to get pushed up by the new content, replaced visually in the viewport.
== Notes ==
Most chat applications will probably want to do a scrollToTop when new content comes in and the user is already scrolled at or near the bottom.
This is glitchy if visible children are re-ordered, which could be fixed with additional logic, but it doesn't come up in the type of applications we're targetting here so punting on that.

Summary:
`ScrollView` has a bunch of `onFoo` handlers for scrolling-related events, most of which have a proptype defined and are documented. However, `onScrollBeginDrag` and `onScrollEndDrag` do not currently have a proptype and are not currently documented (as noted at https://stackoverflow.com/a/41793747/1709587). It seems reasonable to bring consistency and to provide documentation of these otherwise hard-to-discover props.
I haven't added or run any tests, and don't plan to do so (beyond waiting and seeing that no existing checks fail in CircleCI).
I have also created a PR to update the documentation at https://github.com/facebook/react-native-website/pull/99

Now the `ScrollView` mock has all the methods available.
React Native tests pass.
To test this specific part of the code,
```sh
$ react-native init Test
$ cd Test/
$ yarn add react-navigation
```
Then, add a simple project that uses `react-navigation`:
```js
import React from 'react';
import { Text } from 'react-native';
import { StackNavigator } from 'react-navigation';
class HomeScreen extends React.Component {
static navigationOptions = {
title: 'Welcome',
};
render() {
return <Text>Hello, Navigation!</Text>;
}
}
const SimpleApp = StackNavigator({
Home: { screen: HomeScreen },
});
export default SimpleApp
```
Run the default render tests:
```js
$ npm run test
```

Summary:
Touch cancel events are currently being ignored by the ScrollView component. Currently scrollview responds both to scroll events and touchStart/touchMove/touchEnd events.
The reason why ScrollView listens to touchStart/touchEnd is so that it can update its `state.isTouching` param. This parameter then is used in `scrollResponderHandleScrollShouldSetResponder` to make the decision if scrollview should set the responder or not. So if `isTouching` is true (we've received touchStart) then ScrollView want to became a JS responder. This in turn is important for the case where we receive scroll events that does not necessarily need to trigger responder change, e.g. we don't want Scrollview to become JS responder if scroll events have been triggered by `scrollTo` in which case setting responder would put the whole responder system in a bogus state (note that responder can be released only by touchEnd or touchCancel, so if there is no touchEnd that follows scroll event then ScrollView will remain the responder and this would break next touch interaction).
It is therefore crucial for the ScrollView to reset `isTouching` state when touchCancel arrives, as otherwise the next scroll event would incorrectly trigger responder change.
On top of that ScrollView seems to be the only component in RN's core that registers to handle touchEnd but ignores touchCancel, which stands agains the comment added to `RCTRootView.cancelTouches` [here](https://github.com/facebook/react-native/commit/c14cc123d#diff-9cd70243bd2af75c613e29972bb1b41cR127).
This problem is difficult to test with a pure RN native app, as on Android it does not surface because of the `responderIgnoreScroll` flag that is being added to every scroll event, and it essentially makes the responder system ignore scroll events so they would never trigger responder change. On the other hand on iOS the cancel events are pretty rare. With pure RN app they can only be triggered by a "system" level interaction (e.g. when system alert dialog appears or when home button is clicked and there is a touch interaction happening). This issue becomes more prominent when RN app is embedded in a more sophisticated application that may use [`RCTRootView.cancelTouches`](1e8f3b1102/React/Base/RCTRootView.h (L130)) method to block RNs gesture recognizers in some cases or with third-party libraries that deals with touch events like [react-native-gesture-handler](https://github.com/kmagiera/react-native-gesture-handler) that also calls into the method when native touch interaction is detected.
