Summary:
Change `RCTImageDownloader` so it stores the `RCTDownloadTaskWrapper` for reuse. Modify `RCTDownloadTaskWrapper` to use associated objects to store the completion/progress blocks.
Summary:
This PR adds 4 native events to NetworkImage.
Using these events I could wrap `Image` component into something like:
```javascript
class NetworkImage extends React.Component {
getInitialState() {
return {
downloading: false,
progress: 0
}
}
render() {
var loader = this.state.downloading ?
<View style={this.props.loaderStyles}>
<ActivityIndicatorIOS animating={true} size={'large'} />
<Text style={{color: '#bbb'}}>{this.state.progress}%</Text>
</View>
:
null;
return <Image source={this.props.source}
onLoadStart={() => this.setState({downloading: true}) }
onLoaded={() => this.setState({downloading: false}) }
onLoadProgress={(e)=> this.setState({progress: Math.round(100 * e.nativeEvent.written / e.nativeEvent.total)});
onLoadError={(e)=> {
alert('the image cannot be downloaded because: ', JSON.stringify(e));
this.setState({downloading: false});
}}>
{loader}
</Image>
}
}
```
Useful on slow connections and server errors.
There are dozen lines of Objective C, which I don't have experience with. There are neither specific tests nor documentation yet. And I do realize that you're already working right now on better `<Image/>` (pipeline, new asset management, etc.). So this is basically a proof concept of events for images, and if this idea is not completely wrong I could improve it or help somehow.

Summary:
Image source uri's prefixed with ~ are expanded into a full path to
the app directory.
For example: `~/Documents/foo.png` is expanded into `Users/arbesfeld/Library/Developer/CoreSimulator/Devices/977988DF-A8BC-4CE5-A27A-75807A6DF085/data/Containers/Data/Application/CBEFC261-5900-4EF9-8646-603BC57B094A/Documents/foo.png`.
This lets us store and use images from the application home directory with the `Image` component:
```
<Image source={{uri: '~/Documents/foo.png', width: 300, height: 300}} />
```

Fixes#1809
Even if a bridge has more than one root view, it's not supported by the js side
right now, and it will keep warning that those timespans had already been
recorded.
Summary:
Introducing the data structure NavigationRouteStack that focused on managing
navigation routes stack.
The goal is to make <Navigatior /> thinner by moving stack management logic into
its own class and make sure it's well-tested.
Teh next step will be cleaning up <Navigatior /> and add `NavigationRouteStack` to
`NavigationContext`.
Summary:
A minor improvement suggestion: `Navigator.getCurrentRoutes()` probably shouldn't return its `routeStack` backing array as-is, because the caller may mutate it, causing the internal state of the navigator to go out of sync. Instead a shallow copy of the routes should be returned.
I stumbled on this problem in my app by attempting to read the navigator state as follows:
```
let routes = Navigator.getCurrentRoutes();
let current = routes.pop();
let previous = routes.pop();
```
Which led to an exception at next navigation event.

Summary:
The `ScrollView` component tells the native side the subview indices of the views to make sticky. The problem is that, once layout-only views are collapsed, the indices are no longer reflective of the original views to make stick to the top.
Summary:
This enables code like:
```js
<ListView renderScrollView={() => <CustomScrollView />} />
```
where CustomScrollView might be inverted or support pull-to-refresh, etc.

Summary:
The context wasn't being explicitly released before, since it'd be immediately
released. Now that the executors are bridge modules, it was only being deallocated
when the modules were released, what caused the threads to not be released at all.
