Summary:
One of the impacts of this bug is that Java is firing timer
completion events into JavaScript for timers that should have
been deleted. JavaScript filters these out so it doesn't impact
the app developer. However, Java is completing more timers
than necessary.
When cleaning up a timer, we were accidentally deleting the
whole set of timers for that context. Instead, we should
just delete that timer from its context.

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:
`mRCTEventEmitter` is used by 2 different threads. It's assigned on the UI thread and it's accessed on the JavaScript thread. Currently, it can be the case that the UI thread assigns `mRCTEventEmitter` and later the JS thread accesses it but still sees null.
This change fixes the issue by marking the `mRCTEventEmitter` variable as `volatile` to ensure that both threads see the same value for `mRCTEventEmitter`.
**Test plan (required)**
This change is currently used in my team's app. We're no longer seeing a crash in `EventDispatcher`.

Summary:
**Motivation:** We have a project that dynamically changes classes in runtime. This component is initialised within the React Native context. Therefor `RCTBatchedBridge` copies the classes before changes are made to them. While React Native is running, changes are made to the classes dynamically. When the project reloads the `RCTBatchedBridge`, it now has an invalid list of classes containing trash pointers. This causes the project to crash on https://github.com/facebook/react-native/blob/master/React/Base/RCTBatchedBridge.m#L288 with EXC_BAD_ACCESS in the DEBUG-mode.
**Solution:** Copy the class list on each reload to get the current state. Since this is only a DEBUG-feature the overhead of this should not be a major issue.

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.

Summary:
This is a revised follow up version from #8574 ( originally implemented in `objc` )
This PR change the implementation in JS suggested by javache
**motivation**
To supports vibration pattern like android.
The [iOS vibration implementation link](http://stackoverflow.com/questions/12966467/are-there-apis-for-custom-vibrations-in-ios/13047464#13047464) mentioned by skv-headless at https://github.com/facebook/react-native/pull/6061#discussion_r54062592, which will not be accepted by apple since that implementation uses a private API. Thus, I use pure public API `NSTimer` to implement it.
**Note**
Since vibration time on iOS is not configurable, there are slightly differences with android.
for example:
**Android Usage:**
`Vibration.vibrate([0, 500, 200, 500])`
==> V(0.5s) --wait(0.2s)--> V(0.5s)
`Vibration.vibrate([300, 500, 200, 500])`
==> --wait(0.3s)--> V(0.5s) --wait(0.2s)--> V(0.5s)
**iOS Usage:**
if first argument is 0, it will not be included in pattern array.

Summary:
This adds support for a controlled `selection` prop on `TextInput` on iOS (Android PR coming soon). This is based on the work by ehd in #2668 which hasn't been updated for a while, kept the original commit and worked on fixing what was missing based on the feedback in the original PR.
What I changed is:
- Make the prop properly controlled by JS
- Add a RCTTextSelection class to map the JS object into and the corresponding RCTConvert category
- Make sure the selection change event is properly triggered when the input is focused
- Cleanup setSelection
- Changed TextInput to use function refs to appease the linter
** Test plan **
Tested using the TextInput selection example in UIExplorer on iOS.
Also tested that it doesn't break Android.

Summary:
Setting the line height with the help of Android-provided StaticLayout is incorrect. A
simple example app will display the following when `setLineSpacing(50.f, 0.f)`
is set: {F62987699}. You'll notice that the height of the first line is a few
pixels shorter than the other lines.
So we use a custom LineHeightSpan instead, which needs to be applied to the text
itself, and no height-related attributes need to be set on the TextView itself.
