Summary:
Nice addition of the recent Flow types for style props in 9c29ee1504, however I think there are some slight issues in the definition.
`type Styles = {[key: string]: Object}` makes sense, as it's referring to the set of named style groups a user creates a `StyleSheet` from, e.g.
```javascript
const styles: StyleSheet = StyleSheet.create({
container: {
height: 20
},
text: {
color: '#999',
fontSize: 12,
},
}: Styles)
```
However `type StyleValue = {[key: string]: Object}` doesn't make sense. You actually want only the `Object` portion of that definition, presuming it's meant to be used like below:
```javascript
type MyTextProps = {
style: StyleProp,
}
<MyText style={{ color: '#999', fontSize: 12 }}>Hello</Text>
```
---
I've also added `void` to the `StyleValue`, as undefined seems to be handled fine, and can be a useful shorthand in JSX.
---
And finally, I've allowed nesting of style prop arrays, by making StyleProp self-referencing, as RN seems to flatten those without issue. This can be important if you're passing in a style prop quite high up the component tree, and sticking it in an array with other styles at several points while it's passed down.

Summary:
`metro-bundler` v0.21 contains a rewritten bundling mechanism, with simplified logic and much faster rebuild times, called delta bundler. This release contains a couple of breaking changes:
* Now, when using a custom transformer, the list of additional babel plugins to apply are passed to the `transform()` method. These are used in non-dev mode for optimization purposes (Check 367a5f5db8 (diff-40653f0c822ac59a5af13d5b4ab31d84) to see how to handle them from the transformer).
* Now, when using a custom transformer outputting `rawMappings`, the transformer does not need to call the `compactMappings` method before returning (check d74685fd1d (diff-40653f0c822ac59a5af13d5b4ab31d84) for more info).
* We've removed support for two config parameters: `postProcessModules` and `postProcessBundleSourcemap`.

Summary:
RCTSurface instance represents React Native-powered piece of a user interface
which can be a full-screen app, separate modal view controller,
or even small widget. It is called "Surface".
The RCTSurface instance is completely thread-safe by design;
it can be created on any thread, and any its method can be called from
any thread (if the opposite is not mentioned explicitly).
The primary goals of the RCTSurface are:
- ability to measure and layout the surface in a thread-safe and synchronous manner;
- ability to create a UIView instance on demand (later);
- ability to communicate the current stage of the surface granularly.

Summary:
We've seen cases (based on logs) where NetInfo is reporting no connectivity, but network requests still work. This will keep status up to date after app foreground <-> backgrounds, since we don't listen to broadcasts when backgrounded.
This is rather difficult to test given we haven't nailed an internal repro (evidence is solely based on device/app logs). Testing has been done to ensure that there are no behavioural changes on devices that were previously working (no regressions).

* **How to migrate**: Add an underscore before the name of the method
* **Why make this breaking change**: These methods are not meant to be public. For example, the exposed `onLayout` function is not a prop that accepts a function like is typical of the rest of React Native but is the internal method that is called when the component's onLayout is triggered.

Summary:
It's currently possible to crash React Native on iOS when using XMLHTTPRequest with onreadystatechange by having the server send a bunch of bad unicode (we found the problem when a bad deploy caused this to happen).
This is due to an integer overflow when handling carryover data in decodeTextData.
Create Express server with mock endpoint:
```js
var express = require('express');
var app = express();
app.get('/', function(req, res) {
res.writeHead(200, {'content-type': 'text/plain; charset=utf-8'});
res.flushHeaders();
res.write(new Buffer(Array(4097).join(0x48).concat(0xC2)));
res.write(new Buffer([0xA9]));
res.end();
});
app.listen(3000);
```
Create React Native application which tries to hit the endpoint:
```js
export default class App extends Component<{}> {
componentDidMount() {
const xhr = new XMLHttpRequest()
xhr.open('get', 'http://localhost:3000', true);
xhr.onreadystatechange = function () {
if(xhr.readyState === XMLHttpRequest.DONE && xhr.status === 200) {
console.warn(xhr.responseText);
}
};
xhr.send();
}
render() {
return null;
}
}
```
Observe that the application crashes when running master and doesn't when including the changes from this pull request.

Summary:
Allow end users to access the YellowBox API so that warnings can be properly ignored via the API first introduced in a974c140db. Based on that API, you should be able to do the following:
```
import { YellowBox } from 'react-native';
YellowBox.ignoreWarnings(['Warning: ...']);
```
However, if you actually try this today, it results in a broken import error.
Verified using an expo instance. First tried without the YellowBox import, observed a failure to import. Then I added the import statement, and observed no warning on my device.
```
import React from 'react';
import { StyleSheet, Text, View, YellowBox } from 'react-native';
YellowBox.ignoreWarnings(['hey']);
export default class App extends React.Component {
render() {
console.warn('hey!');
return (
<View style={styles.container}>
<Text>Open up App.js to start working on your app!</Text>
<Text>Changes you make will automatically reload.</Text>
<Text>Shake your phone to open the developer menu.</Text>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',
},
});

Summary:
We noticed that on Android the lineHeight behaviour is different from iOS for built in fonts and custom fonts. The problem becomes visible when the lineHeight approaches the fontSize, showing a cut-off on the bottom of the TextView. This issue has been raised before in #10712. There is a mention of a PR with a fix in that issue, which has not been merged yet. This implementation is a less intrusive fix leaving the current lineHeight approach in place and fixing the discrepancy only.
This proposed change prioritises ascent over descent for reduction, making the lineHeight functionality behave identical to iOS.
There is no existing test covering the lineHeight property and its behaviour in the CustomLineHeightSpan. This PR contains new unit tests that covers the various scenario's for the lineHeight calculations.
The original behaviour, before the change can against these unit tests. The case that fails is `shouldReduceAscentThird`, which can be made to succeed on the old code by changing the asserts to:
```
assertThat(fm.top).isEqualTo(-5);
assertThat(fm.ascent).isEqualTo(-5);
assertThat(fm.descent).isEqualTo(-4);
assertThat(fm.bottom).isEqualTo(-4);
```
The unit test succeeds for the current implementation, which has the values for ascent and descent inverted.
