Summary:
Allows you to do:
```
var { RecyclerViewBackedScrollView } = require('react-native')
```
Rather than:
```
var RecyclerViewBackedScrollView = require('react-native/Libraries/Components/ScrollView/RecyclerViewBackedScrollView')
```
Also...
- 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.
- Add `RecyclerViewBackedScrollView` to `MainReactPackage`
- Fix an issue with `MapView` that threw a red-screen when trying to access constants on Android because there is no `MapView` in open source and MapView.js doesn't have a platform extension.

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.
