Summary:`WindowedListView` is designed for memory efficient scrolling of
huge/infinite lists of variable height rows. It works by measuring row heights
with `onLayout` and caching the results, then unmounting rows that scroll
offscreen, replacing them with an equivalent offset in the spacer view. Care is
taken to render a constant number of rows, and to only render one new row per
tick to improve framerate and app responsiveness. WLV is also compatible with
<Incremental> used within the rows themselves.
`WindowedListView` is not a drop-in replacement for `ListView` - it doesn't
support many of the features of `ListView`, such as section headers, only
accepts a simple array of data instead of a datasource, and doesn't support
horizontal scrolling. This may change in the future.
This is still experimental - we haven't deployed this for any production apps
yet.

Summary:I'm [getting rid of it from React](https://github.com/facebook/react/pull/6376) and so I'd like to get this in before we accidentally break RN. There are a bunch of other uses of Object.assign directly so this should be perfectly safe.

Summary:If you're working on an app that needs to support landscape, reloading the app causes the iPhone simulator to reset its orientation to portrait every time the `RCTDevLoadingView` shows up. This is because it sets the root VC to `RCTModalHostViewController`, which currently supports only portrait orientations on iPhone. Changing the root view to a vanilla `UIViewController` fixes the issue.
**Steps to Reproduce**
1. Create a blank RN project: `react-native init RNTest`
2. Open it up and run it.
3. Rotate to landscape `Cmd+Right Arrow`.
4. Reload by pressing `Cmd+R`.
**Expected**
The simulator stays in landscape mode.
**Actual**
The simulator goes back to portrait.

Summary:BUCK is faster than Gradle.
For example `gradle app:installDebug` vs `buck install app` is ~7 seconds vs ~2 seconds with warm caches.
This is just the beginning to allow people to become familiar with BUCK.
It is enough for running the app locally and testing on a device.
Gradle is still used for dependency resolution.

Summary:In projects where you have multiple apps or a different structure (ios is not the directory containing the xcode project) it would be helpful to have the option to configure the directory containing the xcode project when doing "react-native run-ios"
As my PR does not change and does not affect UI it's hard to show a video ;-) Steps to reproduce are:
1. checkout facebook/react-native
2. run 'react-native run-ios' (it will fail)
3. npm link react-native (with my PR)
4. re-run 'react-native run-ios --ios-project-path Examples/Movies/
Now the simulator should open the Movies example app

Summary:A need for sending a scroll events outside of scrollview made D3092854 a bit clunky. This diff kinda fixes it by tightening up emitting of fake scroll events just to the only usecase we have right now.
Why not just simply construct the event in `RCTNavigator`, so we can drop the code from `RCTScrollView` altogether?
`RCTScrollEvent` is private to `RCTScrollView`, and that's good. We don't want anyone have an ability to make up scroll events. Even this existing functionality should be sunset one day when we better integrate with native gesture recognizers.
Depends on D3092867.

Summary:Previously, (mostly touch and scroll) event handling on iOS worked in a hybrid way:
* All incoming coalesce-able events would be pooled and retrieved by js thread in the beginning of its frame (all of this happens on js thread)
* Any non-coalesce-able event would be immediately dispatched on a js thread (triggered from main thread), and if there would be pooled coalesce-able events they would be immediately dispatched at first too.
This behavior has a subtle race condition, where two events are produced (on MT) in one order and received in js in different order.
See https://github.com/facebook/react-native/issues/5246#issuecomment-198326673 for further explanation of this case.
The new event handling is (afaik) what Android already does. When an event comes we add it into a pool of events and dispatch a block on js thread to inform js there are events to be processed. We keep track of whether we did so, so there is at most one of these blocks waiting to be processed. When the block is executed js will process all events that are in pool at that time (NOT at time of enqueuing the block).
This creates a single way of processing events and makes it impossible to process them in different order in js.
The tricky part was making sure we don't coalesce events across gestures/different scrolls. Before this was achieved by knowing that gestures and scrolls start/end with non-coalesce-able event, so the pool never contained events that shouldn't be coalesced together. That "assumption" doesn't hold now.
I've re-added `coalescingKey` and made touch and scroll events use it to prevent coalescing events of the same type that should remain separate in previous diffs (see dependencies).
On top of it it decreases latency in events processing in case where we get only coalesce-able events. Previously these would be processed at begging of the next js frame, even when js would be free and could process them sooner. This delay is done, since they would get processed as soon as the enqueued block would run.
To illustrate this improvement let's look at these two systraces.
