Summary:This adds a BUCK file to UIExplorer to allow building it with buck. It is based on the one in the movies app but I removed the extra deps that were not needed in both files.
Also add build version number and target sdk version in the Android manifest so Buck can use it since it was only specified in the gradle build and caused the app to run on a super old target sdk.
bestander mkonicek Would it be simple to also build the ndk part with Buck? Right now it is built with gradle and packaged after. I suppose it is already being done internally at facebook. The BUCK files for building the cpp code are already there but I couldn't figure out what was missing to make it work :(
That is pretty much the only missing part to have first class support for building RN apps with Buck in OSS. We could eventually include BUCK files with the generated project.
**Test plan (required)**
Build and run UIExplorer and Movies examples using Buck.

```
...with...
```
$1 React = require('react');
$1 ReactNative = require('react-native')$2ReactNative;

I used lint to figure out if I left some unnecessary imports.
Finally I grepped for just
```
React\s*=\s*require\('react\-native'\)

to catch any remaining patterns.
Also, `} = React.NativeModules` -> `} = ReactNative.NativeModules`.

Summary:Current docs show an Appetize.io example for AlertIOS doc. This pull request adds that feature across all applicable iOS and Android docs. So if a doc has an example in UIExplorer, it shows up in the top right and clicking to Play should navigate to the relevant example.
The changes here also touched NavigationExperimental to fix a typo that prevented iOS deep link from working. Code was also added to help support Android deep links but there's an outstanding issue (a race condition) around how Android deep links trigger getInitialURL in NavigationRootContainer that prevents this from fully working.
For adding the docs, a few things were done outside this pull request:
1/ Release builds for UIExplorer Android and iOS apps were uploaded to Appetize.io. The Appetize.io info (public key to run the build) is embedded in the docs.
2/ The iOS build was generated by making a few changes to get a local bundle. The current UIExplorer set up doesn't support "react-native run-ios".

Summary:D3092867 / 1d3db4c5dc caused deadlock when chrome debugging was turned on, so it was reverted as D3128586 / 144dc30661.
The reason: I was calling `[_bridge dispatchBlock:^{ [self flushEventsQueue]; } queue:RCTJSThread];` from main thread and expecting it will `dispatch_async` to another,
since a held lock was being accessed the dispatched block and was released after the dispatch.
Turns out `RCTWebSocketExecutor` (which is used when chrome debugger is turned on) executes all blocks dispatched this way to `RCTJSThread` synchronously on the main thread.
This resulted in a deadlock. The "dispatched" block was trying to acquired lock which held by the same thread in the dispatching phase.
A fix for this is pretty simple. We will release the lock before dispatching the block.
However it's not super straightforward to see this won't introduce some race condition in a case with two threads where we would end up with events not being processed.
My thinking why that shouldn't happen goes like this: We could get in a bad state if `flushEventsQueue` would run on JS thread while `sendEvent:` is running on MT.
(I don't have a specific example how, maybe it's not possible. However when I show this case is safe we know we are good.)
The way how locking is setup in this diff the only possible scenario where these two threads would execute in these methods concurrently is JS holding the lock and MT going to enqueue another block on JS thread (since that's outside of "locked" zone).
But this scenarion can never happen, since if MT is about to enqueue the block on JS thread it means there cannot be a not yet fully executed block on JS thread.
Therefore nothing bad can happen.
So this diff brings back the reverted diff and adds to it the fix for the deadlock.

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.

Summary:This adds a `HEIGHT` constant on `StatusBar` on Android. I needed only this for now but I will work on a better status bar dimensions API later (see TODO).
It also improves the implementation to fix a bug that happened when multiple `StatusBar` components get updated in the same frame as well as remove useless calls to the `StatusBarModule` when values did not change.
Instead of calling the `StatusBarManager` immediately when the component gets updated and relying on the order of the calls that get dispatched to native we now wait at the end of the frame to send the calls to the `StatusBarManager` using `setImmediate`. To make this work properly we need to change the data structure of the props stack a little bit to store the desired transition/animation too for each value.
Finally this updates the example to only show the ones that work for the current platform.
**Test plan**
In the UIExplorer Example, in the 'StatusBar dimensions' section it should show 25 for the height of the status bar.

After we updated to ESLint 2.x, ESLint started complaining `'use strict' is unnecessary inside of modules strict`.
This is correct behaviour because according to spec modules are strict.
The problem is that our transforms don't transpile strict mode so we still need to have this pragma in all our code.
I did not find a way to make eslint require "use strict" for ES6 modules: https://github.com/eslint/eslint/issues/2785
So I am removing this.
What stops us from automatically adding strict mode with babel?
