da0b139b56 Improve Flow types
Summary:
Some of the flow types were incomplete. So, I referenced the code in  `~/fbsource/xplat/js/react-native-github/ReactAndroid/src/main/java/com/facebook/react/views/textinput/` and in `~/fbsource/xplat/js/react-native-github/Libraries/Text/TextInput/` to make the flow types more specific.

I also fixed internal breakages. To avoid having to sprinkle `$FlowFixMe`s everywhere, I had to refactor some types, and some code.

Summary:
Related to #22100

Turn on Flow strict mode for TextProps.
I used ResponseHandlers type definition defined in Text.js.

I wanted to move ResponseHandlers type to TextProps and reuse it inside the file.

Unless having a straightforward solution, I found it clearer to copy paste these types.

70826dbafc iOS: Support inline view truncation (#21456)
Summary:
If text is truncated and an inline view appears after the truncation point, the user should not see the inline view. Instead, we have a bug such that the inline view is always visible at the end of the visible text.

This commit fixes this by marking the inline view as hidden if it appears after the truncation point.

This appears to be a regression. React Native used to have logic similar to what this commit is adding: 1e2a924ba6/Libraries/Text/RCTShadowText.m (L186-L192)

**Before fix**

Inline view (blue square) is visible even though it appears after the truncation point:

![image](https://user-images.githubusercontent.com/199935/46382038-d3a71200-c65d-11e8-8179-2ce4aad8d010.png)

The full text being rendered was:

```
<Text numberOfLines={1}>
  Lorem ipsum dolor sit amet, consectetur adipiscing elit,
  sed do eiusmod tempor incididunt ut labore et dolore magna
  <View style={{width: 50, height: 50, backgroundColor: 'steelblue'}} />
</Text>
```

**After fix**

Inline view is properly truncated:

![image](https://user-images.githubusercontent.com/199935/46382067-fdf8cf80-c65d-11e8-84ea-e2b71c229dae.png)

**Test Plan**

Tested that the inline view is hidden if it appears after the truncation point when `numberOfLines` is 1 and 2. Similarly, verified that the inline view is visible if it appears before the truncation point.

**Release Notes**

[IOS] [BUGFIX] [Text] - Fix case where inline view is visible even though it should have been truncated

27cfba2882 Remove useless additionnal blur call (#22156)
Summary:
I noticed that the _onBlur method was not exactly similar to the _onFocus one in the TextInput component.

After digging, I found that the blurTextInput method in the TextInputState.js file was call twice in a raw instead of once when the textinput component should blur.

By removing this line, I fix this unecessary multiple call.

bea3bb6956 DrawerLayoutAndroid: Convert to ES6 class (#21980)
Summary:
This pull requests converts `DrawerLayoutAndroid` from a `createReactClass`-based component to an ES6 class component, removing its use of `NativeMethodsMixin` and `prop-types` in the process.

Unfortunately this couldn't be moved over to a full `forwardRef` to the native component, because it has the methods `openDrawer` and `closeDrawer` as part of its API, and they can't be called directly on the native component. A `createRef`-based ref to the native component can be accessed from the `nativeRef` property of a `DrawerLayoutAndroid` instance if a native ref is needed.

The Flow types for callbacks have also been filled out.

6f34bc4016 Back out "reapply TextInput es6 conversion with fixes, attemps to fix"
Summary:
Back it out again. This time really not sure why this is breaking, but it seems to be production only. The error seems to be "RCTSinglelineTextInputView" was not found in the UIManager" but the relavent logic is not changed in this diff, just moved around, so unclear why it would trigger a failure.

Reverting to be safe. When we re-apply the diff, we'll need to test a full OTA to prod to verify the fix.

aacb06c594 Fix React Native AsyncMode and DevTools
Summary:
Fixes two problems I uncovered with React Native:
1. `FBCore/Prelude` points to `React.unstable_AsyncMode` which is not defined. (This type was renamed to `React.unstable_ConcurrentMode` in React v16.6.0. **As a result** people in the "react_native:async_rendering" GK will no longer get runtime errors on app start.
2. Updates `react-devtools` and (more importantly) `react-devtools-core` to 3.4.2 to handle the React-internal tag/type refactoring that happened prior to the release of 16.6.0. **As a result** DevTools will no longer cause a runtime error when connected to React Native.

For the second change, I ran `js1 upgrade react-devtools -v ^3.4.2`

c787866d64 Clearer HMR error messages
Summary:
GraphNotFoundError: When the user moves the app to the background on Android, restarts the Metro server and reopens the app, since the client hasn't requested either a delta or a bundle, the graph cache of the server is empty and thus we can't compute an update for the client (what if changes happened when the metro server was down?).

RevisionNotFoundError: I didn't manage to reproduce that one. It could happen if two clients live side-by-side, requesting the exact same bundle. In the future, if we want to handle that case, we'll need to manage a list of clients listening to a single graph so that we don't try to update the same graph multiple times for a single file change.

Disconnection: Same as GraphNotFoundError, but happens when the user moves the app to the background on iOS.

69213eea95 Flow strict TouchableOpacity (#22146)
Summary:
Related to #22100

Enhance Flow types for TouchableOpacity specifying Touchable event types and TvParallaxPropertiesType.
I had to export TvParallaxPropertiesType from TVViewPropTypes file.
There are still 1 any left using requireNativeComponent and a dependency to `Touchable` that need to be addressed to turn Flow to strict mode.

I guess `Touchable` is a lot more work since there's no flow annotation and it's still good old Mixin.

- All flow tests succeed.

Summary:
Related to #22100

Turn on Flow strict mode for StaticContainer.react
This component needed proper Props type definition. I went through the only component (`TabBarItemIOS.ios`) using this to try to know the most appropriate props.

- All flow tests succeed.

84c5416617 Flow type RefreshControl (#22119)
Summary:
Related to #22100

Enhance Flow types for RefreshControl specifying `onRefresh` props type.
There are still 2 `any` left using `requireNativeComponent` that need to be addressed to turn Flow to strict mode.

I went through `RCTRefreshControl` and `AndroidSwipeRefreshLayout` classes to understand where this method came from.

- All flow tests succeed.

54f7eb3424 Performance improvement for loading cached images on iOS (#20356)
Summary:
This PR increases the speed at which cached images are loaded and displayed on the screen. Images are currently cached in memory using RCTImageCache, but each time they are loaded, a round trip through RCTNetworking happens before RCTImageCache is even checked. This is likely so that RCTNetworking can handle the caching behavior required by the HTTP headers. However, this means that at the very least, images are read from disk each time they're loaded.

This PR makes RCTImageLoader check RCTImageCache _before_ sending a request to RCTNetworking. RCTImageCache stores a bit of information about the response headers so that it can respect Cache-Control fields without needing a roundtrip through RCTNetworking.

Here are a couple of graphs showing improved loading times before this change (blue) and after (red) with SDWebImage (yellow) as a baseline comparison. The increase is most evident when loading especially large (hi-res photo size) images, or loading multiple images at a time.

More performance gains can potentially be had by increasing the size limit of RCTImageCache: 1a6666a116/Libraries/Image/RCTImageCache.m (L39) but this comes at the tradeoff of being more likely to run into OOM crashes.
