Summary: @public
Take a step back and de-batch the bridge calls so we can have better profiling data and a better starting point to work on future optimisations. Also gave a 10~15% win on first render.

Summary:
This will throw an error message with the problematic callback module/method. Previously we would get an invariant in this case when we try to access `callback.apply` later in the method.

After refactoring the MessageQueue a guard was missing on around `batchedUpdates`
call.
Test Plan: Introduce an error on `getInitialState` of `AdsManagerTabsModalView.ios.js`
Summary:
@public
The current implementation of `MessageQueue` is huge, over-complicated and spread
across `MethodQueue`, `MethodQueueMixin`, `BatchedBridge` and `BatchedBridgeFactory`
Refactored in a simpler way, were it's just a `MessageQueue` class and `BatchedBridge`
is only an instance of it.
Test Plan:
I had to make some updates to the tests, but no real update to the native side.
There's also tests covering the `remoteAsync` methods, and more integration tests for UIExplorer.
Verified whats being used by Android, and it should be safe, also tests Android tests have been pretty reliable.
Manually testing: Create a big hierarchy, like `<ListView>` example. Use the `TimerMixin` example to generate multiple calls.
Test the failure callback on the `Geolocation` example.
All the calls go through this entry point, so it's hard to miss if it's broken.

This removes the last piece of data that was still stored on the DATA section,
`RCT_IMPORT_METHOD`. JS calls now dynamically populate a lookup table simultaneously
on JS and Native, instead of creating a mapping at load time.
Test Plan: Everything still runs, tests are green.

`[Bridge] Add support for JS async functions to RCT_EXPORT_METHOD` was imported but broke some internal code, reverting the `MessageQueue` that caused the issues and add a test, since the method is not used yet.

Summary:
Adds support for JS async methods and helps guide people writing native modules w.r.t. the callbacks. With this diff, on the native side you write:
```objc
RCT_EXPORT_METHOD(getValueAsync:(NSString *)key
resolver:(RCTPromiseResolver)resolve
rejecter:(RCTPromiseRejecter)reject)
{
NSError *error = nil;
id value = [_nativeDataStore valueForKey:key error:&error];
// "resolve" and "reject" are automatically defined blocks that take
// any object (nil is OK) and an NSError, respectively
if (!error) {
resolve(value);
} else {
reject(error);
}
}
```
On the JS side, you can write:
```js
var {DemoDataStore} = require('react-native').NativeModules;
DemoDataStore.getValueAsync('sample-key').then((value) => {
console.log('Got:', value);
}, (error) => {
console.error(error);
// "error" is an Error object whose message is the NSError's description.
// The NSError's code and domain are also set, and the native trace i

Summary:
@public
Right now the profiler shows how long the executor took on JS but doesn't show
how long each of the batched calls took, this adds a *very* high level view of JS
execution (still doesn't show properly calls dispatched with setImmediate)
Also added a global property on JS to avoid trips to Native when profiling is
disabled.
Test Plan:
Run the Profiler on any app

Summary:
Wraps the setImmediate handlers in a `batchUpdates` call before they are synchronously executed at the end of the JS execution loop.
Closes https://github.com/facebook/react-native/pull/1242
Github Author: James Ide <ide@jameside.com>
Test Plan:
Added two `setImmediate` calls to `componentDidMount` in UIExplorerApp. Each handler calls `setState`, and `componentWillUpdate` logs its state. With this diff, we can see the state updates are successfully batched.
```javascript
componentDidMount() {
setImmediate(() => {
console.log('immediate 1');
this.setState({a: 1});
});
setImmediate(() => {
console.log('immediate 2');
this.setState({a: 2});
});
},
componentWillUpdate(nextProps, nextState) {
console.log('componentWillUpdate with next state.a =', nextState.a);
},
```
**Before:**
"immediate 1"
"componentWillUpdate with next state.a =", 1
"immediate 2"
"componentWillUpdate with next state.a =", 2
**After:**
"immediate 1"
"immediate 2"
"componentWillUpdate with next state.a =", 2
