Summary:
.android.js files may be checked (when the next version of flow is released) by using `flow start --flowconfig-name .flowconfig.android` and `flow status --flowconfig-name .flowconfig.android`
This diff adds suppressions to the errors that are in .android.js files, which flow does not check right now.
When site is `react_native_fb` or `react_native_android_fb`, error will be suppressed when checking with .flowconfig.android
When site is `react_native_fb` or `react_native_ios_fb`, error will be suppressed when checking with .flowconfig.
You can use `react_native_fb` when it should be suppressed for both.

Summary:
This PR fixes an issue I have found while playing with native animated driver nodes.
I discovered the bug when using animated views that have both animated props and styles. See this snack to see an example: https://snack.expo.io/B17SFXy8Q
In that example we set `opacity` and `style` props which both contain animated props. This is not an usual way to do that, as normally you would place `opacity` inside the `styles` in which case the bug won't surface. But this is only done for demo purposes and in practice the problem will occur if you have a custom native view that exposes props that are not styles and can be animated.
In the above example you get this error:
> Invariant Violation: Attempt to get native tag from node not marked as "native"
When `opacity` is moved into `styles` container the problem no longer occurs.
The problem turned out to be related to the initialization code responsible for creating native animated nodes. In all subclasses of `AnimatedWithChildren` (like `AimatedAddition`) we only call `super.__makeNative` after we call `__makeNative` method on the child nodes. This order was reversed in `AnimatedStyle` and `AnimatedTransform`. As a result when `super.__makeNative` is called in `AnimatedStyle`, we try to call `__getNativeTag` on children nodes not yet marked as native which results in the error described above ("Attempt to get native tag...").
We should instead follow the order of calling `super.__makeNative` that is used in the remaining subclasses of `AnimatedWithChildren`. Such that all the children nodes are first converted to native prior to calling superclass method. This is what this PR is changing.

This diff fixes two bugs:
1. When you load a `<WebView/>` with an HTML source string, HTML source doesn't render in the `<WebView/>`. Instead, we get this warning: https://pxl.cl/grz3. Here's what the above page should look like when correctly rendered: https://pxl.cl/grzt
2. Furthermore, you render a blank `<WebView/>` (i.e: with no source prop), it should display a blank page. Instead, we get this warning: https://pxl.cl/grz3
**Bugfix:**
One solution I found was to ensure that `about:blank` is always whitelisted. That way, we don't ever abort navigations to blank pages, which occur when we do:
```ObjectiveC
/** Line 134 in RCTWebView.m */
[_webView loadHTMLString:@"" baseURL:nil];
```
and
```ObjectiveC
/** Line 115 in RCTWebView.m */
if (html) {
NSURL *baseURL = [RCTConvert NSURL:source[@"baseUrl"]];
if (!baseURL) {
baseURL = [NSURL URLWithString:@"about:blank"];
}
[_webView loadHTMLString:html baseURL:baseURL];
return;
}

As we just now started tracking Circle CI on our internal builds, I want to make sure we only nag internal diffs when the failure can actually be attributed to the diff. The failures in the e2e tests precede the Circle CI integration and are adding unnecessary noise.
Going forward, we will immediately go back to a diff and push the author to fix the broken CI, so this PR is a temporary fix.

**Summary**
This pull request bumps Babel to 7.0.0-beta.56 to incorporate the latest bugfixes from Babel.
**Test plan**
One way to test is to add a simple TypeScript file with a type as the default export:
```typescript
export const test = 1
export default interface A {}
```
and then import that file from any other file:
```js
import { test } from './typescript-test'
```
Before this would throw an error, but with the latest Babel this is now fixed.

Summary:
Most of the changes associated with this commit will not be visible on GitHub, as they concern files in the internal Facebook monorepo. The bulk of this change is the addition of a new test that runs on the internal test infrastructure. The actual script used by the test has various references to the internal test infra, but a copy is produced below with some changes that should allow it to run on open source should anyone be interested in testing this outside of Facebook.
The test has the main goal of catching common sources of FB-to-GitHub breakages, such as the OSS Flow config falling out of date (we use a different flow config than what is synced out in .flowconfig, and hence internally we rename this file to .github.flowconfig). It also checks that the packager can run on a brand new project, among other things.

Summary: This helps prevent race condition where JS calls to NativeModules got queued and executed while the bridge is invalidating itself, causing assertion failures in test setup (for example). It won't prevent it 100% of the time, due to threading (and adding lock is expensive for each nativemodule call).

Summary:
On iOS, it is not possible to select a range of text using a `Text` component (see #13938). Because of how the `Text` component is implemented on iOS, this will not work without a complete re-write. On Android however, this is not an issue.
As the `TextInput` component has evolved, it can more or less be used as a drop-in replacement on iOS by setting `multiline={true}` and `editable={false}`. Except for one detail: the text input field has scrolling activated and it's not possible to turn off. (See #1391 and #15962).
This pull request addresses that issue, simply by exposing the `scrollEnabled` property:
```
<TextInput
multiline
editable={false}
scrollEnabled={false}
/>
```
1. Create a multiline `TextInput` component, with the attributes presented above.
2. Run on iOS
3. The `TextInput` field should not be able to scroll

Summary:
Currently, we scan all native modules to see if they implement the OnBatchCompleteListerner. If they do, we add those modules to a list, and when C++ calls OnBactchComplete is called, we execute the callback on each of the modules.
The only native module implementing this callback today is the UIManagerModule. With Fabric, UIManager will also not be a native module anymore. This diff removes all the work done for creating the list and assumes that UIManagerModule is the only place that is interested in OnBatchComplete call - and calls it directly.

Summary:
Implemented a version of accessibility Hints on android by adding hint text to the end of contentDescription. There is already an existing prop on js and iOS implementation.
Changes involve:
* adding a prop on native android code for accessibilityHints
* setting the accessibilityDelegate after the props are all loaded.
* Instead of directly updating the accessibility delegate, the prop setters now update state by setting the values of the variables. Once all props are set, the accessibility delegate is set based on the props
* BaseViewManager keeps track of whether or not accessibility props have been set
* AccessibilityDelegateUtil keeps track of what the props have been set to. (Renamed AccessibilityRoleUtil to AccessibilityDelegateUtil)
Currently, this is the easiest way of emulating the way accessibility hints work on iOS, and I think having an android counter part is better than having nothing.
It's different from iOS in that it will announce the hint before the role, and also cannot be turned off.
Ex:
if I set the accessibility like this:
```
<View
style={styles.container}
accessible={true}
accessibilityLabel="accessibility label"
accessibilityRole="button"
accessibilityStates={['selected']}
accessibilityHint="accessibility Hint">
<Text> Tester </Text>
</View>
```
Talk back will read:
`accessibility label, accessibility Hint, button, selected`
In the future for next steps, I plan on investigating the process of making a second announcement after the first

To avoid unnecessary copying of `shared_ptr`s inside ShadowNodeFragment, now we store them as `const &` references.

Now we use same data structure to specify a shape of shadow node as we use in ShadowNode (sub)clases.

When we copy-construct ShadowNode, we don't need to retain a source shadow node, so there is no need to pass it as a `shared_ptr`. Passing an argument to constructor as `const &` is also more idiomatic in C++.

Summary:

ShadowNode class is designed to share `props` and `children` objects between instances. Given that all *Props classes are immutable, it's very easy to share them and we do this from the day one. The `children_` collection is more tricky though because ShadowNode class has a couple of mutation methods. Previously, we dealt with it very simply by copying the whole vector in constructors, and that was far from optimal. Now we store a special flag that indicates that the children list is shared among nodes, and we clone this before the first mutation.
Sharing a `shared_ptr` should be much more efficient (cost of atomic refcount increment) than instantiating whole new collection (an allocation).
