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:

On D2099270 event coalescing was implemented and the event key on the RCTSparseArray
is an uint64_t, but it was declared as NSUInteger. On a 32 bits architecture
it'll be clipped to 4 bits, meaning that just `reactTag` will be taken into
account, e.g. different types of events can coalesce with each other if they target the same view
Switching to use an NSMutableDictionary instead of RCTSparseArray and NSNumber
as keys instead of uint64_t
Test Plan: Fixed the previous tests and added a new test to RCTEventDispatcherTests
Summary:
Previously, if you were already inspecting an element, touching again would
select a completely different element because the touch position was
calculated relative to the current overlay.
This fixes it.
@public
Test Plan:
Open the inspector, click around, verify that every click selects the thing
you clicked on.
Summary:
Wraps the setImmediate handlers in a `batchUpdates` call before they are synchronously executed at the end of the JS execution loop.

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

This adds a parameter for fetching videos from the camera roll. It also changes the default to fetch both videos and photos.

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

For some reason we were manually JSON-encoding the RCTDataManager responses, and then decoding them again on the JS side. Since all data sent over the bridge is JSON-encoded anyway, this is pretty pointless.
Test Plan:
* Test Movies app in OSS, which uses RCTDataManager
* Test any code that uses RKHTTPQueryGenericExecutor to make network requests (e.g. Groups)
* Test the Groups photo upload feature, which uses RKHTTPQueryWithImageUploadExecutor
Summary:

`RCTUIManager` would traverse the whole view hierarchy every time there was any
call from JS to Native to call `reactBridgeDidFinishTransaction` on the views
that would respond to it. This is a deprecated method that is only implemented
by 3 classes, so for now we keep track of these views as they're created and
just iterate through them on updates.
Test Plan:
> NOTE: I tested this on UIExplorer, since the internally none of the classes are used
I tried to keep it simple, so I added the following to the old code:
```
__block NSUInteger count = 0;
UIView *rootView = _viewRegistry[rootViewTag];
RCTTraverseViewNodes(rootView, ^(id<RCTViewNodeProtocol> view) {
count ++;
if ([view respondsToSelector:@selector(reactBridgeDidFinishTransaction)]) {
[view reactBridgeDidFinishTransaction];
}
});
NSLog(@"Views iterated: %zd", count);
```
The output after scrolling 20 sections of the `<ListView> - Paging` example was
```
2015-06-01 00:47:07.351 UIExplorer[67675:1709506] Views iterated: 1549
```
*every frame*
After the change
```
for (id<RCTViewNodeProtocol> node in _bridgeTransactionListeners) {
[node reactBridgeDidFinishTransaction];
}
NSLog(@"Views iterated: %zd", _bridgeTransactionListeners.count);
```
```
2015-06-01 00:51:23.715 UIExplorer[70355:1716465] Views iterated: 3
```
No matter how many pages are loaded, the output is always 3.
Summary:
So when I first started porting JS files over from LearnGitBranching into a react native project, I some had require errors (for whatever reason) and I hit this error message a decent amount. I eventually understood it had nothing to do with failing to register the component (which btw sounds like some sign-up process, not actually an internal concept) but I figured we could expand on this message and describe why it might be happening.
I'm not 100% sure on what the second half should be, but open to feedback on this
