Summary:
The example of `BackAndroid` caused a bit of confusion for beginners (see #8822), so I thought we should clarify the functionality a bit. I added a comment indicating that a user would have to implement `this.onMainScreen` and `this.goBack` on their own, this was the original problem.

Summary:
`BackAndroid` JS event subscriptions should be called in reverse order
(the subscription from the latest `addEventLister` should run first).
Also if listener returns true, don't call other listeners.
**Motivation**: We use `BackAndroid` listeners to prevent closing screens with user's input.
When we have two screens in stack (each screen with listener, which show alerts),
we want to show alert only from the last screen listener, not from all.

Summary:sometimes it is nessesary to handle back button
specifically for component, by changing its state.
For ex. exit from edit mode.

Summary:
…while an event is dispatched
While it is guarded, a copy of the Set is created before listeners are added or removed. The event dispatch loop continues with the old Set of listeners.
This PR modifies `BackAndroid` to match the proposal at the end of #5781.

Summary:
public
Map and Set are a standard JavaScript features, but are only supported in a subset of JSC versions that we target (e.g. iOS 7's JSC doesn't support Set).
The consequence of this is that failing to require('Set') before using it won't error during testing on a modern OS, but will fail on older OS versions. This diff makes the Map and Set polyfills available globally to all RN apps to avoid that problem.

This is an early release and there are several things that are known
not to work if you're porting your iOS app to Android.
See the Known Issues guide on the website.
We will work with the community to reach platform parity with iOS.
