Summary:
If tracking is enabled and the sampling check passes on a scroll or layout event,
we compare the scroll offset to the layout of the rendered items. If the items don't cover
the visible area of the list, we fire an `onFillRateExceeded` call with relevant stats for
logging the event through an analytics pipeline.
The measurement methodology is a little jank because everything is async, but it seems directionally
useful for getting ballpark numbers, catching regressions, and tracking improvements.
Benchmark testing shows a ~2014 MotoX starts hitting the fill rate limit at about 2500 px / sec,
which is pretty fast scrolling.
This also reworks our frame rate stuff so we can use a shared `SceneTracking` thing and track blankness
globally.

Summary:
Enable back navigation on Apple TV (with the remote's menu button) in code making use of BackAndroid. The module is renamed to BackHandler. BackAndroid is still exported to ReactNative for now, until external projects switch to using the new name for the module. The navigation in https://github.com/react-community/react-navigation makes use of this module.
**Test plan**: Manual testing with an example app (https://github.com/dlowder-salesforce/react-nav-example).

Summary:
The PR description has been updated to reflect the new approach.
**Breaking Change Summary**
On Android, the following properties now return a different number:
- `Dimensions.get('window').fontScale`
- `Dimensions.get('screen').fontScale`
- `PixelRatio.getFontScale()`
This is a breaking change to anyone who was using these properties because the meaning of these properties has now changed.
These properties used to return a value representing font scale times density ([`DisplayMetrics.scaledDensity`](https://developer.android.com/reference/android/util/DisplayMetrics.html#scaledDensity)). Now they return a value representing just font scale ([`Configuration.fontScale`](https://developer.android.com/reference/android/content/res/Configuration.html#fontScale)).
**PR Description**
This PR changes a few things:
- Correctly exposes the font scale to JavaScript as `Dimensions.get('screen').fontScale`. UIManager was exporting `DisplayMetrics.scaledDensity` under the name `fontScale`. How

Summary:
On Android with dev mode on, we're seeing a regular SIGSEGV when pushing a lot of animation declarations over the bridge. We tracked this down to being not specific to animations, but the crash is caused in `deepFreezeAndThrowOnMutationInDev`.
Specifically: the provided object to freeze is modified while looping, replacing the current key access to a getter/setter. After the modification, JSC crashes during retrieval of the next key - but only when there are a lot of events passing over the bridge.
We have a hunch that this is due to a bug in JSC object enumeration but did we not look into it further yet. Any help here is welcome. The JS code seems all right at first sight and shouldn't cause a segmentation crash.
The workaround in this PR is to retrieve the keys first from the object and then looping over that array. In our app and in a reduced app test case this fixes the crash.
If needed I can provide the reduced app test case. It's really tricky to make a test for this as it requires to be run

Summary:
`BackAndroid.addEventListener()` returns a subscription object with a `remove()` function in android. Before this fix, the iOS equivalent doesn't return anything, which means, if there's a component doing something like this, it would redbox:
```
componentWillMount() {
this._subscription = BackAndroid.addEventListener('hardwareBackPress', () => {...});
}
componentWillUnmount() {
this._subscription.remove(); // --> redbox in iOS before this fix
}

Summary:
The MessageQueue has a _debugInfo object where it stores debug information associated with each callback. The size of this structure is currently unbounded.
It looks like the code attempted to restrict _debugInfo to a fixed number of entries but due to a logic bug, it leaked around 30 entries for every 1 entry it cleaned up.
This change limits the _debugInfo object to around 30 entries.

This change is currently being used in my team's app.

This brings RN up to date with https://github.com/facebook/react/pull/7472 (scheduled for React 15.3.1).
If you use React 15.3.1 with RN without this patch, Systrace output will lack the reconciler events.
(Since it’s a niche feature it didn’t seem to me that full backward compat is necessary so I just removed old hooks. This won’t cause crashes—it’s just you won’t get events in Systrace if you use new React but old RN.)

Summary:
**Motivation**
In iOS you cannot dismiss alerts by clicking outside of their box, while on Android you can. This can create some inconsistency if you want to have identical behavior on both platforms. This change makes it possible for Android apps to have irremovable/required alert boxes just like in iOS.
This adds an additional parameter to the Alert method. The way to use it is by providing an object with the cancelable property. The cancelable property accepts a boolean value.
This utilizes the Android DialogFragment method [setCancelable](https://developer.android.com/reference/android/app/DialogFragment.html#setCancelable(boolean))
**Usage example**
```js
Alert.alert(
'Alert Title',
null,
[
{text: 'OK', onPress: () => console.log('OK Pressed!')},
],
{
cancelable: false
}
);
```
**Test plan (required)**
