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:
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:
lineBreakMode is a non-existing property (or maybe legacy?)
While reading the docs I encountered this prop being used in the example, but it doesn't exist in the codebase anymore.

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.
Concreate example which this approach supposed to fix:

Summary:
The `requestIdleCallback` sometimes doesn't work in `Debug JS Remotely` mode if I use real device, the callback will never called. I guess it may be debugger worker and device caused by the time gap, or some cause websocket blocking, so it's just sometimes happening.
I think we can support [options](https://developer.mozilla.org/zh-TW/docs/Web/API/Window/requestIdleCallback#Parameters) for that.
Added an example `Run requestIdleCallback with timeout option` for Timers of UIExplorer, it use `{ timeout: 100 }` option with burn CPU 100ms, we can see `didTimeout` is true.

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:
Singleline <TextInput> now has intrinsic size which is equal to size of placeholder.
And if <TextInput> does not have placeholder it still has intrinsic height.
So, we don't need to set the size up manually every single time anymore!
(Multiline <TextInput> already has this feature.)

Summary:
Previously <TextInput>'s onContentSizeChange event fires very rearly, usually just once after initial layout. This diff fixed that.
I also considered to a bunch of another things to get the native notification, but I found that overriding `onTextChanged` is the most reliable, easy and effitient way to implement this.
I tried/considered:
* onLayout (does not fire)
* OnPreDrawListener (fires to often)
* OnGlobalLayoutListener (does not fire)
* OnLayoutChangeListener (does not fire)
* isLayoutRequested (too hacky)
(I also fixed the <AutoExpandingTextInput> demo to illustrate the fix.)
And just heads up, we will remove `contentSize` info from `onChange` event very soon.

Summary:
Fixes https://github.com/facebook/react-native/issues/13784
The section footer was only rendered with the last item of the section. However, that meant in sections where no items were rendered, no section footer would be rendered. This patch makes sure that when there are no items the section footer is rendered with the section header in addition to adding tests asserting the existance of section footers in empty lists.
One potential point of contention is whether or not a section separator (as defined by the `SectionSeparatorComponent` prop to `<SectionList>`) should be rendered in an empty list. I did not include a section separator for empty lists, but let me know if you think one should be included. See the test plan below for an image of an empty section rendered without a section separator.
I was also running into a lint error, `no-alert`, in `SectionListExample.js` around line 135 that blocked me from publishing. This error looks to be triggered when the `alert()` global function is called, so to fix the error I added an import for the `Alert` module and called the `alert()` function on that module.
To help debug the `scrollToLocation()` behavior that was modified as a part of this PR I added three buttons (can be seen in the test plan image) which scroll to arbitrary points in the list.

Summary:
**Motivation**
The ART library is part of the react-native repo, but is not included in UIExplorer and has no native testing. This PR adds the ART library to UIExplorer, adds an example tab for it, and adds a snapshot test.

New snapshot test.

Summary:
We are removing support of nesting views inside <Image> component. We decided to do this because having this feature makes supporting `intrinsinc content size` of the `<Image>` impossible; so when the transition process is complete, there will be no need to specify image size explicitly, it can be inferred from actual image bitmap.
And this is the step #0.
<ImageBackground> is very simple drop-in replacement which implements this functionality via very simple styling.
Please, use <ImageBackground> instead of <Image> if you want to put something inside.
