Summary:
This fixes measuring of items in the main axis of a container. Previously items were in a lot of cases measured with UNSPECIFIED instead of AT_MOST. This was to support scrolling containers. The correct way to handle scrolling containers is to instead provide them with their own overflow value to activate this behavior. This is also similar to how the web works.
This is a breaking change. Most of your layouts will continue to function as before however some of them might not. Typically this is due to having a `flex: 1` style where it is currently a no-op due to being measured with an undefined size but after this change it may collapse your component to take zero size due to the implicit `flexBasis: 0` now being correctly treated. Removing the bad `flex: 1` style or changing it to `flexGrow: 1` should solve most if not all layout issues your see after this diff.

Summary:
Hi there,
when using the ScrollView component with `onScroll` and `scrollEventThrottle = 0` as it is documented in [react-native/docs/scrollview](https://facebook.github.io/react-native/docs/scrollview.html#scrolleventthrottle) this message will appear unnecessary.
This happens because `!this.props.scrollEventThrottle` is `true` when the value is `0`.
So I changed it to `this.props.scrollEventThrottle == null`. Now it is `false` when the value is `0`.

Summary:
This adds support for sticky headers on Android. The implementation if based primarily on the iOS one (https://github.com/facebook/react-native/blob/master/React/Views/RCTScrollView.m#L272) and adds some stuff that was missing to be able to handle z-index, view clipping, view hierarchy optimization and touch handling properly.
Some notable changes:
- Add `ChildDrawingOrderDelegate` interface to allow changing the `ViewGroup` drawing order using `ViewGroup#getChildDrawingOrder`. This is used to change the content view drawing order to make sure headers are drawn over the other cells. Right now I'm only reversing the drawing order as drawing only the header views last added a lot of complexity especially because of view clipping and I don't think it should cause issues.
- Add `collapsableChildren` prop that works like `collapsable` but applies to every child of the view. This is needed to be able to reference sticky headers by their indices otherwise some subviews can get optimized out and break indexes.

Summary: Introduce `overflow:scroll` so that scrolling can be implemented without the current overflow:visible hackiness. Currently we use AT_MOST to measure in the cross axis but not in the main axis. This was done to enable scrolling containers where children are not constraint in the main axis by their parent. This caused problems for non-scrolling containers though as it meant that their children cannot be measured correctly in the main axis. Introducing `overflow:scroll` fixes this.

Summary:
I noticed that even when a ScrollView's `keyboardShouldPersistTaps` prop is set to true, the ScrollView's children can still respond to tap events (even if the scroll view itself will not respond to tap events and the keyboard does not dismiss automatically). This is a point of ambiguity in the React Native docs; it implies that no touch events can be handled if `keyboardShouldPersistTaps` is set to true.

Summary:
In Android, `RecyclerViewBackedScrollView` wasn't using `refreshControl` prop.
If a ListView were created with `RecyclerViewBackedScrollView` as its `renderScrollComponent`, then the `refreshControl` wouldn't work.
example:
```js
<ListView
dataSource={this.props.dataSource}
renderRow={this._renderRow.bind(this)}
refreshControl={
<RefreshControl
refreshing={this.props.isRefreshing}
onRefresh={this._onRefresh.bind(this)}
/>
}
renderScrollComponent={props => <RecyclerViewBackedScrollView {...props} />}/>;
```
This works in iOS, since the `RecyclerViewBackedScrollView` just returns an `ScrollView`.
This pull request uses the `refreshControl` to decide whether it should wrap the `NativeAndroidRecyclerView` with an
`AndroidSwipeRefreshLayout` or not.
This fixes the issue #7134.

Summary:
This adds support for pagingEnabled to the HorizontalScrollView.
This is an initial implementation.
Because Android doesn't provide great details about what is happening with a scroll view after you are done touching it, we have some post touch handling. This is kicked off either by touch up or a fling call.
Once we are doing that handling, we start a runnable that basically checks if we are still scrolling. If we are, we just schedule that runnable again and check a frame later. If we are done scrolling (no onScrollChanged since we last fired), we could be in one of two states, the fling is done or we are done snapping to the page boundary. If we are in the fling done case, we then check if we need to scroll to a page boundary. If so, we call smoothScrollTo and schedule ourself to check onScroll events again until done with that scroll. If we are done with both (either we only did momentum scroll or we did that and then snapped to page), we can then fire the final event and stop checking. This logic is all in handlePostTouchScrolling.
Because of the decision to only do page scrolling after momentum ends, we do allow you to scroll through with momentum a number of pages and the transition can be a little strange where it stops a sec and then slides to be page aligned. As a follow up, we can probably smooth that up by changing the value we pass to super.fling() that would adjust it to be let momentum carry it to the page boundary.

Summary:
The issue is that the ScrollResponder mixin assumes that the native scrollable node is the top level element and gets it using `React.findNodeHandle(this)` but since Android wraps the native `ScrollView` component with the `RefreshControl`, it finds the native `RefreshControl` node instead and the scroll command gets ignored because it doesn't exists.
This adds a hook to ScrollResponder mixin to allow specifying what is the native scrollable node.

ScrollView.scrollTo(5, 0, true) // what do these arguments mean?
This diff replaces the API with a configuration object, so the arguments are all explicit:
ScrollView.scrollTo({x: 0, y: 5, animated: true}) // much better
The `scrollTo()` method checks the argument types, and provides backwards compatibility with the old argument format for now. Using the old API will generate a warning, and this will eventually be upgraded to an error.

Summary:
Both iOS and Android currently support some sort of native pull to refresh control but the API was very different. I tried implementing a component based on PullToRefreshViewAndroid but that works on both platforms.
I liked the idea of wrapping the ListView or ScrollView with the PullToRefreshView component and allow styling the refresh view with platform specific props if needed. I also like the fact that 'refreshing' is a controlled prop so there is no need to keep a ref to the component or to the stopRefreshing function.
It is a pretty rough start so I'm looking for feedback and ideas to improve on the API before cleaning up everything.
On iOS we could probably deprecate the onRefreshStart property of the ScrollView and implement the native stuff in a PullToRefreshViewManager. We could then add props to customize the look of the UIRefreshControl (tintColor). We could also deprecate the Android only component and remove it later.

- Export `ScrollView` by default rather than `UnimplementedView` for `RecyclerViewBackedScrollView` on iOS -- this makes it easier on the user, so you don't have to always do a conditional for: `if IOS then use ScrollView else use RecyclerViewBackedScrollView`. I can't think of a case where this would lead to undesirable behaviour.

Summary: The recent commits for RecyclerViewBackedScrollView introduced a bunch of Flow errors.
Disable Flow for now in `ReactNativeViewPool` as it looks like that file doesn't use Flow :)

Summary: public
Changed ListView to use onLayout and onContentSizeChange (new) events instead of measure. Updated ScrollView implementation to support contentSizeChange event with an implementation based on onLayout attached to the content view. For RecyclerViewBackedScrollView we need to generate that event directly as it doesn't have a concept of content view.
This greatly improves performance of ListView that uses RecyclerViewBackedScrollView

Summary: `ScrollView.scrollWithoutAnimationTo` is supported on iOS but not Android. This is an existing API, and this diff adds Android support.

Summary:
The `ScrollView` component tells the native side the subview indices of the views to make sticky. The problem is that, once layout-only views are collapsed, the indices are no longer reflective of the original views to make stick to the top.
Summary:
Remove layout-only views. Works by checking properties against a list of known properties that only affect layout. The `RCTShadowView` hierarchy still has a 1:1 correlation with the JS nodes.
This works by adjusting the tags and indices in `manageChildren`. For example, if JS told us to insert tag 1 at index 0 and tag 1 is layout-only with children whose tags are 2 and 3, we adjust it so we insert tags 2 and 3 at indices 0 and 1. This keeps changes out of `RCTView` and `RCTScrollView`. In order to simplify this logic, view moves are now processed as view removals followed by additions. A move from index 0 to 1 is recorded as a removal of view at indices 0 and 1 and an insertion of tags 1 and 2 at indices 0 and 1. Of course, the remaining indices have to be offset to take account for this.
The `collapsible` attribute is a bit of a hack to force `RCTScrollView` to always have one child. This was easier than rethinking out the logic there, but we could change this later.

Test Plan: There are tests in `RCTUIManagerTests.m` that test the tag- and index-manipulation logic works. There are various scenarios including add-only, remove-only, and move. In addition, two scenario tests verify that the optimization works by checking the number of views and shadow views after various situations happen.
Summary:
As discussed in our internal group, think this is a fairly easy error to run into so I added some explanation.
@frantic / @vjeux open to better wording here, but I tried to explain how setting the height directly is discouraged and it's probably better to pipe `flex: 1` all the way down.
I didn't regenerate the website since the script assumes some permissions (push permission to master repo) and has some missing npm dependencies (and after fixing that, still had some obscure error :P )

Summary:
This is a proposal to add `getScrollResponder` to all ScrollView-like components, including ListView. This allows multiple higher-order scroll views to be composed while allowing the owner of the top-level scroll view to call `scrollableView.getScrollResponder().scrollTo(...)` regardless of whether `scrollableView` is a ScrollView, ListView, InvertedScrollView, etc.

Summary:
Implementing the consensus approach from the comments on
this PR:
https://github.com/facebook/react-native/pull/486
We use a boolean flag in the Obj-C code to determine whether
to animate or not, and then provide two public JS functions
that call the Obj-C with or without the flag.

The `bounces` property lets you disable rubber-banding. It was already exposed on the native side so this diff is just documenting it in JS.
