Summary:
This PR adds a capability for MessageQueue to emit "SPY" events in a way that can be extensible, to later allow for a tooling ecosystem to grow, one example is the existing [Snoopy](https://github.com/jondot/rn-snoopy) tool that is, for now, forced to work with monkeypatches, and after this PR will be able to use a "formal" way to trace queue events.
After this change, we can wire a "spy" into a queue that will expose the events in different and interesting ways, see below (done with Snoopy):

This removes the hardcoded `SPY_MODE` flag and instead uses a function that can be injected from outside world.

When call `[RCTDevMenu invalidate]`, it will cancel updateTask. But in fact, after the `[updateTask cancel]`, the updateTask's completionHandler will call `checkForUpdates` again, so it will create a new updateTask.

Summary:
The animation shown in the UIExplorer example for NavigationExperimental's NavigationHeader is not working correctly. Due to an incomplete use of the `renderTitleComponent()` callback, interpolation is not working correctly in this example.
Even if the animation error is subtle, since the examples are followed by developers quite closely, the bug may multiply if not corrected in the sample code.
This is a really *tiny* modification that fixes that particular animation.

Summary:
We've been getting a lot of documentation PRs opened against `0.29-stable`, `0.30-stable`, and so on, instead of `master`. This is because our doc site is also based on RN release cuts, so clicking on the "Edit on GitHub" links on a document will take you to the markdown source for that release branch instead of the latest doc on `master`.
See #9095 for an example of such a PR.
In this PR we edit the link to say View on GitHub. Though it may not prevent PRs from being opened against a release branch, removing the "Edit" CTA may help in this regard.

Summary:
Because it is react, the url could be changed on redirection or some other ways.
The iOS version's WebView has controled that on [here](https://github.com/facebook/react-native/blob/master/React/Views/RCTWebView.m#L106).
But the Android's one is not.
Check the url is same with privous url. If it is true, cancel loading.
This logic is same with iOS's.
the ```method``` hasn't compared.
Test urls as we can.

Summary:
The docs heavily implied that this method returned a notification object or null directly, like popInitialNotification used to do. In fact, it returns a promise. This change clarifies this.
Note that:
- This is purely a comment change, so no testing required.
- I've adhered to the 80 character line limit, and can't think of any other style rules you might have that could apply here.

Explain the **motivation** for making this change. What existing problem does the pull request solve?
Example code for "Using Navigators" under "THE BASICS" does not work. renderScene needs to return the components, not just instantiate them.
**Test plan (required)**
I copy-paste and ran the code but did not get anything rendered. I added a return statement before the component which made it work.
Arrow functions need a return statement when supplying a { block of code }.

The issue here is that sometimes `this.options()` is not `[options]` but contains different stuff, esp. if your command accepts arguments.

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.

**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
