Summary:This brings back "Use numeric identifiers when building a bundle", previously backed out.
This version passes on the correct entry module name to code that decides transform options.
Original Description:
Since the combination of node and haste modules (and modules that can be required as both node and haste module) can lead to situations where it’s impossible to decide an unambiguous module identifier, this diff switches all module ids to integers. Each integer maps to an absolute path to a JS file on disk.
We also had a problem, where haste modules outside and inside node_modules could end up with the same module identifier.
This problem has not manifested yet, because the last definition of a module wins. It becomes a problem when writing file-based unbundle modules to disk: the same file might be written to concurrently, leading to invalid code.
Using indexed modules will also help indexed file unbundles, as we can encode module IDs as integers rather than scanning string IDs.

Summary:This makes the `refreshing` prop more 'controlled'. Before forgetting to set the refreshing prop in the onRefresh callback would make the js and native `refreshing` prop get out of sync and make the RefreshControl stop refreshing properly (see #5839).
I also added a simple usage example and a note about the refreshing prop in the doc.
There was also a small bug in the doc generation code that made the array of color show as [[object Object]] instead of [color] so I fixed that too.
** Test plan**
Tested using the UIExplorer example on iOS and Android. Not setting the `refreshing` prop to true in the `onRefresh` function should cause the RefreshControl to stop refreshing immediately and continue working properly after.

Summary:**Motivation**
AppStateIOS never currently returns `inactive` as a possible state. I had a requirement that when inactive, certain portions of the app should be blacked out in accordance with compliance rules. This is not possible currently, due to `inactive` never being returned. This PR fixes that.
**Test plan**
All base tests are passing. Are there AppState specific tests in place at the moment that I'm missing?

Summary:Everything wrapped in `<Incremental>` is rendered sequentially via `InteractionManager`.
The `onDone` callback is called when all descendent incremental components have
finished rendering, used by `<IncrementalPresenter>` to make the story visible all at once
instead of the parts popping in randomly.
This includes an example that demonstrates streaming rendering and the use of
`<IncrementalPresenter>`. Pressing down pauses rendering and you can see the
`TouchableOpacity` animation runs smoothly. Video:

Ideally this will be baked into React Core at some point, but according to jordwalke that's
going to require a major refactoring and take a long time, so going with this for now.

Summary:**Motivation**
Multiple instances of `Text` inside a `ListView` is a bad idea for the performance of the app.
When you create 1000 elements and you scroll through the list it is really slow and laggy because the `NSTextStorage`, which is the backbone of the `RCTText` element, will set more than 1,000 times and also the method `setNeedsDisplay` is called multiple times. This will causes huge memory problems and the app crashes.
With this commit I check in `RCTText` if the `NSTextStorage` differs from the old value. If yes then set it otherwise don't set the `NSTextStorage`. This will prevent to call `setNeedsDisplay` when not really needed.

Summary:Given that you can do all kinds of animations other than `Animated.timing`, it made no sense to have `setTiming`. In addition, you can't intuitively tell that this is the callback where you would do custom animations.

1. When calling startObserving or getCurrentPosition for the first time, _locationManager is not initialized and the accuracy value set in options is lost.
2. When using the cached location _lastLocationEvent, current timestamp retrieved by CFAbsoluteTimeGetCurrent() is from 2001, but the timestamp of the location is from 1970. In addition, the comparison between _lastLocationEvent[@"coords"][@"accuracy"] and options.accuracy is incorrect. Less value indicates more accurate location.

Summary:025281230de2e316f2770a2db71f8bec6fe43a07 changed `WebSocket` to fire both `onerror` and `onclose`.
However, `setupDevtools` assumed that only one of the two handlers would ever be invoked. When the handler is invoked, it re-invokes itself to keep a socket open. But since both handelrs are invoked, a series of closed or failed sockets can cause an exponential increase in sockets opened.
Symptoms of this bug include eventually reaching the maximum number of file descriptors allowed by the operating system, or a non-responsive system. Within React Native applications, symptoms include a failure to load resources from the React Native server or application crashes.

Summary:Motivation: Developer expects `onclose` to be called before/during close of the websocket. The `websocketFailed` event triggers a close but does not invoke onclose.
Testplan: Connect to a websocket server from android, terminate the server, observe that onerror is called, the websocket is closed, but onclose is not called.
Note: the observed bug is in android only because in iOS the underlying websocket implementation fires the `websocketClosed` rather than `websocketFailed` event when the server terminates. Nevertheless, the justification for this change stands that regardless of the cause of the close, if `this.close` is called it is expected this.onclose should be called as well.
