Summary:
As per https://twitter.com/olebegemann/status/738656134731599872, our use of "main thread" to mean "main queue" seems to be unsafe.
This diff replaces the `NSThread.isMainQueue` checks with dispatch_get_specific(), which is the recommended approach.
I've also replaced all use of "MainThread" terminology with "MainQueue", and taken the opportunity to deprecate the "sync" param of `RCTExecuteOnMainThread()`, which, while we do still use it in a few places, is incredibly unsafe and shouldn't be encouraged.

Summary:
The `removeClippedSubviews` feature works by umounting views from the hierarchy if they move outside the bounds of their parent.
This was previously restricted to clipping views which had `overflow: hidden`, since we cannot efficiently check whether the subviews of a view go outside its bounds, and so clipping a view that has potentially overflowing children becomes an expensive recursive operation.
The problem with this is that `overflow: visible` is the default, and it's not well documented nor easy to tell that `removeClippedSubviews` has been set up correctly (i.e. with all children having `overflow: hidden`).
When I checked, I found that `removeClippedSubviews` was not working on any of the examples in UIExplorer, nor in several of our internal apps, because the views inside the ListView has `overflow: visible`. This was probably caused by an infra change at some point, but I'm not sure how long it's been broken.
It's vanishingly unlikely that anyone would ever deliberately want subviews to overflow their bounds in this scenario, so I've updated the logic to simply ignore the `overflow` property and assume that views should be clipped if you are using the `removeClippedSubviews` property on the parent.
Cons / Breaking changes: in some rare circumstances, a view might get clipped prematurely if its parent is outside the scrollview bounds, but it itself is inside. This doesn't occur in practice in any of our products, and could be worked around with additional wrapper views if it did.
Pros: removeClippedSubviews is now much easier to use, and much more likely to work as intended, so most list-based apps should see a performance improvement.

Summary:
RCTScrollView was calling `dockClosestSectionHeader` in `reactBridgeDidFinishTransaction`, which triggers a layout update. The reason for this was in case the `stickyHeaderIndexes` property was updated, which would require the headers to be adjusted.
However, doing this in `reactBridgeDidFinishTransaction` had the affect of causing `layoutSubviews` to be called repeatedly every frame even if nothing had changed and the scrollview wasn't moving, which was especially expensive when combined with the `removeClippedSubviews` logic, that loops through every view to calculate if it needs to be clipped.
This fix moves the `dockClosestSectionHeader` call into `didUpdateProps`, and checks that the stickyHeaderIndexes have actually changed before calling it.

Summary:
Implement a handler to allow intercepting all RN redboxes in Android, including exceptions in both JS and Java.
The handler is not open sourced, so there is only an open-source interface called **RedBoxHandler** in //fbandroid/java/com/facebook/catalyst/js/react-native-github/ReactAndroid/src/main/java/com/facebook/react/devsupport//, meantime there is an internal class called **FBRedBoxHandler**, which implements **RedBoxHandler** and is located in //fbandroid/java/com/facebook/fbreact/redboxhandler//, actually handles the exception information.
The code structure is as follows:
- **AdsManagerActivity** has a member variable of **FBRedBoxHandler**.
- **AdsManagerActivity** passes this handler all the way down to the **DevSupportManagerImpl**, through** ReactInstanceManager**, **ReactInstanceManagerImpl**, **DevSupportManagerFactory**.
- **DevSupportManagerImpl** intercepts the exceptions just before showing the redboxes, like this:
mRedBoxDialog.setExceptionDetails(message, stack);
mRedBoxDialog.setErrorCookie(errorCookie);
if (mRedBoxHandler != null) {
mRedBoxHandler.handleRedbox(message, stack);
}
mRedBoxDialog.show();
By now, the internal class just prints information for each redbox to logcat, including exception message and stack trace.

Summary:
**Motivation**
Today it's hard to build a good flow around requesting permissions if we don't know when the user rejects the push notification permission.
With this PR I wrap `PushNotificationIOS#requestPermission` in a promise. The promise will return with the updated permissions when the user accepts, rejects or has previously rejected the permission.
An example flow of how an app should handle push notifications with the change proposed:
1) Show user an explanation of push notification permissions with a button to enable,
2) User presses the enable push notifications button,
3) If the user accepts -> take them into the app,
4) if the user rejects -> explain how to enable permission in the settings app.
5) My app will now store some state about how it has asked permissions for push notifications so that the next time the user is taken through this flow they will go straight to step 4.
Without this change we could listen to the `register` event that PushNotificationIOS fires on the success sc

Summary:
The TextInput when configured with `multiline=true` has a minor issue due to which if the initial text doesn't fit in one line, the input won't span multiple lines. The root cause of the problem is that the `onChange` event is not fired for the initial render. This issue has been reported on open-source: 481f560f64
This is an attempt to fix this problem by moving the logic to fire the event to the method that updates the content size. This way we can guarantee that anytime the content size changes we'll trigger the JS event.
The downside of this approach is that it's possible that multiple events get fired for a single character change. As per the comment that was removed, this was already happening when adding a character that when rendered, would increase the content size. By moving the code to the new place, this can happen more often (twice per character tapped). Let me know if you think this is an issue.
I don't know this code much, so please be careful reviewing. I'm happy to add more test cases I may have missed to the test plan :).
