Summary:
Sometimes is handy to check if a React node is a descendant of another node or not. For instance, I want to check if the focused `TextInput` is descendant of an specific `ScrollView`:
```js
const currentlyFocusedField = TextInput.State.currentlyFocusedField()
UIManager.viewIsAncestorOf(
currentlyFocusedField,
this.getInnerViewNode(),
(isAncestor) => {
if (isAncestor) {
console.log('The focused field is a descendant of this ScrollView!')
}
}
)
```
This function uses the same strategy as the `measureLayout` method to check if one node is an ancestor of other node. As the `measureLayout` method, this is performed outside the main thread.
By now I've only implemented the iOS version and its tests, but if this function is going to be merged I'll implement the Android version too. I have objc experience but no Java or Android, so I prefer to validate this functionality before jumping into developing the Android part.

Summary:
When compiling 0.31-rc1 was having issues with xcode running the package script and failing (ie not running and returning the --help info) Was due to this - simply changing the flag to --reset-cache instead of --reset-cache true worked miracles.
**Test plan (required)**
Ran packager without and runs but doesn't build the package, runs with small change and works now. Can copy paste output if you want but it's pretty super verbose for this small change.

Prior to the RNPM integration, command names would match the second argument passed to the react-native-cli. Now the command names contain some usage information (such as non-flag CLI arguments). This commit splits the name of the commands and checks that against the second command line argument.

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:
**This is the first part of `React.createClass` -> ES2015 classes migration.
1. Rewritten UI Explorer ActivityIndicator example to ES2015 classes
2. Removed TimerMixin from example.
Motivation:
- ES2015 classes do not support mixins so due to the classes / pure functions as "best practices" it would be better to avoid mixins in examples.
- TimerMixin is covered later and is out of scope of current example.

Summary:
This diff addresses the issues raised by kmagiera in https://github.com/facebook/react-native/pull/7884. Transforms should be applied in the order they are defined, just like in `processTransform.js`. A scale applied before a translation, for instance, should give a different result than a translation applied before a scale.
We leverage CATransform3D to do the heavy lifting. A concatenated transform is passed all the way to `RCTViewPropertyMapper`. It is compared with the transform currently applied to the view, and if different, applied. The same approach is used for opacity.
I think it makes the most sense to do this diffing in `RCTViewPropertyMapper`, as opposed to creating and cleaning up an `_updatedPropsDictionary` each frame in `RCTTransformAnimatedNode` and `RCTStyleAnimatedNode`. The node should keep its full value; applying a minimal set of altered props is an optimization. The higher up this optimization is implemented, the more assumptions it makes. e.g. that there will only ever be a sing

This diff enables network inspection for WebSocket APIs, so by now XMLHttpRequest, Fetch and WebSocket are all supported. Android and iOS are both supported.
This diff monkey-patches the RCTWebSocketModule which WebSocket API builds on, and now it is able to intercept all WebSocket requests when app is running. The intercepted information of a WebSocket includes url, protocols, status, messages (sent and received), close reason, server close event and server error information, etc.

Summary: In previous `XHRInterceptor`, it sometimes crashes when restarting the network inspector because the id of the XHR objects are not unique all time. Fix this in diff by adding a global id "generator" for all intercepted xhr objects in order to make it safe across inspector restarts.

Summary:
This pull request fixes cases where the `error` argument of the `onUnhandled` method in `Libraries/Promise.js` is undefined. Previously this would result in a redbox with the helpful message: `Cannot read property message of undefined`. With this pull request, unhandled promise rejections result in the desired yellowbox saying that a promise rejection went unhandled.
I still do not know what would cause the error argument to be undefined, but this change makes the module behave as expected in an app I am building.

Summary:
We have a lot of small-ish calls to JSC and within the bridge that add up during TTI. This gives us a way to measure them in aggregate in a reasonable way.
From the comments:
MicroProfiler is a performance profiler for measuring the cumulative impact of
a large number of small-ish calls. This is normally a problem for standard profilers
like Systrace because the overhead of the profiler itself skews the timings you
are able to collect. This is especially a problem when doing nested calls to
profiled functions, as the parent calls will contain the overhead of their profiling
plus the overhead of all their childrens' profiling.
MicroProfiler attempts to be low overhead by 1) aggregating timings in memory and
2) trying to remove estimated profiling overhead from the returned timings.
To remove estimated overhead, at the beginning of each trace we calculate the
average cost of profiling a no-op code section, as well as invoking the average
cost of invoking the system clock. The former is subtracted out for each child
profiler section that is invoked within a parent profiler section. The latter is
subtracted from each section, child or not.
The usage is similar to Systrace: you put a MICRO_PROFILER_BLOCK in the block you want to profile and C++ RAII will handle timing it.
After MicroProfiler::stopProfiling() is called, a table of tracing data is emitted
to glog (which shows up in logcat on Android).

I verified that in Android 4.1.2 ScrollView#mScroller exists as a private on ScrollView, but there's still potential that this could break things if OEMs have modified ScrollView so we just log a warning if we can't get access to that field.

On iOS, if `TextInput` is used with prop `multiline={true}`, the backend view is `UITextView`. Sometimes we need `UITextView.dataDetectorTypes` to detect clickable url in the text view. The PR add this prop to `TextInput`, so we can use it like this:
`<TextInput`
` defaultValue="Detect phone number: 88888888."`
` editable={false}`
` multiline={true}`
` dataDetectorTypes="all"`
` />`
