Summary:
Flashing scroll indicators is a standard behavior on iOS to show the user there's more content.
Launch RNTester on iOS, go to the ScrollView section, tap the "Flash scroll indicators" button.
You'll see this:
![Flash scroll indicators](https://cloud.githubusercontent.com/assets/57791/26250919/ebea607a-3cab-11e7-96c6-27579cc809ab.gif)
I've exposed the method `flashScrollIndicators` on all scrolling components that were already exposing a `scrollToXXX` method so it's usable from those components using a ref.
Let me know what you think.

Summary:
Sometimes, when we implement some custom RN view, we have to proxy all accessible atributes directly to some subview which actually has accesible content. So, in other words, this allows bypass some axillary views in terms of accessibility.

Summary:
This change introduces some APIs that are useful for making announcements through the screen reader on iOS:
- `announceForAccessibility`: The screen reader announces the string that is passed in.
- `announcementFinished`: An event that fires when the screen reader has finished making an announcement.
You can already solve similar problems with RN Android using the `accessibilityLiveRegion` prop. Live regions are a different feature but they can be used to solve the same problem. This commit does not attempt to add live region support in RN iOS because Apple did not build live region support into iOS.
Verified that `announceForAccessibility` causes VoiceOver to announce the string when VoiceOver is enabled. Verified that `announcementFinished` fires with the appropriate data in the event object. Additionally, my team has been using this change in our app.

Summary:
Motivation:
* We maintain two different implementation of <TextInput> (multilined and singlelined), this change makes the implementations much similar which will help us to support and improve both of them in the (near) future;
* We have to have separated RCTView-based container view for (TextField) to support sofisticated bordering and so on;
* It opens to us possibility to unify UITextView and UITextField subclasses and remove code duplication across RCTTextView and RCTTextField;
* Making things decoupled in general will allow us to fix existing bugs with events.

Summary:
This change introduces an API, `setAccessibilityFocus`, which moves the screen reader's focus to the passed in element. This causes VoiceOver to announce the element and draw a focus rectangle around it.
Similar functionality is already available in RN Android through the `sendAccessibilityEvent` method. Here's an example of what exists today in RN Android:
```
RCTUIManager.sendAccessibilityEvent(
node,
8 /* TYPE_VIEW_FOCUSED */);
```
Called `setAccessibilityFocus` on a couple of elements to verify that focus does indeed move when VoiceOver is enabled. Additionally, my team is using this change in our app.

Summary:
In some cases, `RCTRecursiveAccessibilityLabel` could return an accessibility label that had leading space, trailing space, or multiple spaces between words. This is because it always added a space before adding a label even if the label turned out to be empty.
This is fixed by being stricter about adding spaces.
Found test cases that used to introduce leading space, trailing space, or multiple spaces between words and verified that there aren't any extra spaces after the fix.
```
{/* Used to have leading space */}
<View accessible={true}>
<View />
<View accessibilityLabel='Two' />
<View accessibilityLabel='Three' />
</View>
{/* Used to have 2 spaces between "One" and "Three" */}

Summary:
React Native uses JSON to marshal the data across the bridge.
And because of this we have to avoid using NaN and INF values in events and other pieces of data that suppose to be transfered to/from JS side.
(We also don't want to introduce additional wrapping/escaping semantics for perfomance reasons.)
So, we have to gate all particular cases where there is a possibility of NaN or INF values, and replace these value with something meaningful for each particular case.
We are using `0` as NaN substitution here because:
* NaN in touch event is super rare case;
* Conversion to `0` is fast;
* `0` is okay value for product code in most cases;
* In all cases `0` is decent analog to "undefined position on screen" for touch event;
* Nobody will explicitly handle NaN case in product code, just because it is super rare case and actually indicates that something else went wrong.

Summary:
This fixes a bug that causes properties to keep stale values because they were not restored to their default after being removed when their value was controlled by native animated.
To fix this we restore default values in `disconnectFromView` by updating views with null values for all props that we modified previously. However this causes another issue where we lose any props that were set by the normal process because NativeAnimated operations are always executed after UIManager operatations. To fix this I added a way to hook into UIManager view updating process to be able to execute NativeAnimated operations either before or after updating native views.
In the case of disconnecting we want to do it before updating views so that it does: Value changed by native animated -> value restored to default -> (optional) value updated by normal prop.
This PR also depends on #10658.

Summary:
While working with `RCTEventEmitter` I noticed that if an event is emitted before `_listenerCount` is updated, it will not go through because the listeners count hasn't been updated. Moving the count update before the invokation of `startObserving` and `stopObserving` fixes the issue. Same way if you remove the last listener and an event is fired before the count is updated (while it shouldn't be fired).
**Test plan (required)**
An easy test to demonstrate it is to implement `startObserving` to synchronously fire an event. Without the change, a warning is thrown, with the change, the event is fired. Not very strong on Obj-C here and I didn't know how to mock out the native stuff. Would be glad to write a failing unit test tho :)

Summary:
Several things:
* The mess with insets was fixed. Previously we tried to compensate the insets difference with `UITextField` by adjusting `textContainerInset` property, moreover we delegated negative part of this compensation to the view inset. That was terrible because it breaks `contentSize` computation, complicates whole insets consept, complicates everything; it just was not right. Now we are fixing the top and left inset differences in different places. We disable left and right 5pt margin by setting `_textView.textContainer.lineFragmentPadding = 0` and we introduce top 5px inset as a DEFAULT value for top inset for common multiline <TextInput> (this value can be easilly overwritten in Javascript).
* Internal layout and contentSize computations were unified and simplified.
* Now we report `intrinsicContentSize` value to Yoga, one step before auto-expandable TextInput.
