Summary:
The previous file/class name convention seemed cool... but now it drives me BANANAS! It makes all this code really hard to maintain.
So, evething were renamed following common modern RN convention.

Summary:
The change enabling virtualization in nested lists contained a hidden assumption that nested lists would only appear within the *cells* of a parent list.
If a list header or footer component contains a `VirtualizedList`, that child list won't be wrapped in a `CellRenderer` component and therefore won't have access to `virtualizedCellRenderer` through its context. This causes an error when the child list tries to access the `cellKey` property on an undefined object.
This change wraps the header/footer views in a `VirtualizedCellWrapper` component which supplies that context properly.

so we don't need JavaScript implementation of this anymore. Sometimes it is even harmfull (see T23403231).

Summary:
This is a long story. Awhile ago awesome Nick Lockwood (Hey Nick!) introduced a special optimization for ReactNative rendering layer called "inherited background color".
He described this idea in D2811031:
>>>
Blending semitransparent pixels against their background is fairly a fairly expensive operation on mobile GPUs. To reduce blending, React Native has a system called "background color propagation", where the background color of parent views is automatically inherited by child views unless explicitly overridden. This means that translucent pixels can be blended directly against a known background color, avoiding the need to do this dynamically on the GPU.
In practice, this is only useful for views that do their own drawing, which is basically just <Image/> and <Text/> components, and for image components it only really matters when the image has an alpha component.
The automatic background propagation is a bit of a hack, and often does the wrong thing - for example if a view overflows its bounds, or if it overlaps a sibling, the background color will often be incorrect and need to be manually disabled. Because the only place that it provides a significant performance benefit is for text, this diff disables the behavior for everything except <Text/> nodes. It might still be useful for <Image/> nodes too, but looking through the examples in UIExplorer, the number of places where it does the wrong thing for images outnumbers the cases where it provides significant reduction in blending.
However. I think it is time to remove it. Why? There are several reasons:
* It drastically complicates rendering layer. DRASTICALLY. In many many unrelated places (try search for "backgroundColor"!);
* This mechanism is totally non-conceptual to RN and it prevents us to implement some new possible render optimization that we plan to do;
* This adopted only by two components now: Text and ART;
* This is not a significant performance drain anymore; from iOS 6 even UILabel has clear background color by default.
* I doubt that it even works now because `drawRect:` in Text component does not call super method.
So, this diff just turns this feature off for Text. If all performance metrics are neutral, I will delete this mechanism.
Peace.

Summary:
Because it is not simply flushing, it (in the future) is more complex process. And the names should represent logical meaning of the process, not particular implementation details.
It also nice to have unified terminology across our reactive UI frameworks.

There are some errors I noticed after upgrading my flow version. I had them in my project, and they were also reported in #11655. These errors were ignored on master, but I went through and fixed them so the static analysis will work still.
After these changes, I receive no errors using flow `0.60.1` on latest master, or using `0.59` in my local project (which does not have the requisite ignores included).
- init a new project
`react-native init --version <path-to-repo> helloworld`
- add the flow binary
`yarn add -D flow-bin`
- run flow
`yarn flow`
- make sure there are no errors in the project.
```
No errors!
✨ Done in 23.60s.

Summary:
This feature has been requested by customers. Our previous (pre-react) application had support for custom accessibility actions.
This feature allows UI elements to provide a list of custom actions that can be read when VoiceOver is enabled. UI elements expose one accessibility action by default. Some UI elements may support multiple actions though other mechanisms like tap and hold. To expose these actions in an accessible way iOS provides custom accessibility actions.
Feature was tested in the iOS simulator using the Accessibility Inspector. Custom actions were added to a button and observed in the tool. Custom actions were also invoked using the tool and then stepped through in the debugger.
The feature was also tested on an iPhone. VoiceOver was enabled on the device and custom actions were observed for controls that exposed them.
We have been using this feature in our app for some time as well.

Summary:
when a hardware keyboard is connected, the virtual keyboard can be hidden (this can easily be demonstrated in the simulator), which means the height of the keyboard is 0. When in this case a `LayoutAnimation` is scheduled, the `KeyboardAvoidingView` won't be affected, but the next layout change will be animated, which can have unintended side-effects. This can also trigger the `Overriding previous layout animation with new one before the first began` warning.
<details>
<summary>Screenshot</summary>
</details>
Open the `KeyboardAvoidingView` example in the `RNTester` project, import `LayoutAnimation` and add something rendered conditionally to the content of the `Modal`, e.g.;
```jsx
{this.state.behavior === 'position' &&
<Text>We're using position now</Text>
}
```
Then update the `onSegmentChange` handler with a `LayoutAnimation`;
```js
onSegmentChange = (segment: String) => {
LayoutAnimation.easeInEaseOut();
this.setState({behavior: segment.toLowerCase()});
};
```
Now open the example in the simulator and play with the "Toggle Software Keyboard" option;
Now when you focus the input, no keyboard should appear, and when you then press an option of the segmented control, you should get the beforementioned warning.
After this change this warning will no longer appear, but the component still behaves the same as before.

WIP: Starting point insofar as I'm not sure if there should be an Android equivalent.
My application needs me to delete photos from the photos in iOS.
I have tested this in my application and it works, have a screenshot from iOS asking as well and it does successfully delete the photos from the global Photos app.
Related to https://github.com/facebook/react-native/issues/15253, it kind of continues using the deprecated assets-library framework, but that does need (and will be an bigger and bigger issue coming up) of assets-library URLs being used.
I also assume RN prefers error handling at the JS level? Are the URLs starting with `asset-library`, etc.

Solves https://github.com/facebook/react-native/issues/13034
Now the `ScrollView` mock has all the methods available.
React Native tests pass.
To test this specific part of the code,
```sh
$ react-native init Test
$ cd Test/
$ yarn add react-navigation
```
Then, add a simple project that uses `react-navigation`:
```js
import React from 'react';
import { Text } from 'react-native';
import { StackNavigator } from 'react-navigation';
class HomeScreen extends React.Component {
static navigationOptions = {
title: 'Welcome',
};
render() {
return <Text>Hello, Navigation!</Text>;
}
}
const SimpleApp = StackNavigator({
Home: { screen: HomeScreen },
});
export default SimpleApp
```
Run the default render tests:
```js
$ npm run test
```
