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:
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:
As discussed with @nicklockwood in the issue https://github.com/facebook/react-native/issues/1780, the error should be changed to a warning to not break fetch() to send a POST to a remote API without wanting to parse the reply. E.g. google sends back an empty 1x1px gif when POSTing something to google analytics.

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:
Android WebView now supports the prop "injectedJavaScript", too.
It's time to rename "injectedJavascriptIOS" to "injectedJavaScript" for API
consistency between IOS and Android.
Summary:
Trivial change to fix the lowercase response headers set for XHR responses.
What would happen is the first iterated header wouldn't be part of `_lowerCaseResponseHeaders`.
Also it would mutate the original `responseHeaders` object, mixing lowercase headers with the original values.

Summary:
This is most of the infra necessary for the gratuitous animation demo app.
I originally had things more split up, but it was just confusing because everything is so interlinked and dependent, so lower diffs would have code that wasn't even going to survive (and thus not useful to review), so I merged it all here.
- `Animated.event` now supports mapping to multiple arguments (needed for `onPanResponderMove` events which provide the `gestureState` as the second arg.
- Vectors: new `Animated.ValueXY` class which composes two `Animated.Value`s for convenience/brevity
- Listeners: values and events can be listened to in order to trigger state updates based on their values. Intended to work as async updates from native that might lag behind truth.
- Offsets: a common pattern with pan and other gestures is to track where you left off. This is easily encoded in the Value directly with `setOffset(offset)`, typically used on grant, and can be flattened back into the base value and reset with `flattenOffset()`, typically called on release.
- Tracking: supports `Animated.Value/ValueXY` for `toValue` with all animations, enabling linking multiple values together with some curve or physics. `Animated.timing` can be used with `duration: 0` to rigidly link the values with no lag, or `Animated.spring` can be used to link them like chat heads.
- `Animated.Image` as a default export.
- Various cleanup, bug, flow and lint fixes.
Summary:
This introduces a new `RCTResponseErrorBlock` block type that allows a bridge module writer to call it with an `NSError` instance rather than a dictionary.
Summary: At the moment the `ListView.js` `_childFrames` variable is only updated on scroll. As a consequence, `onChangeVisibleRows` won't get triggered for the initial render, nor any future render not trigered by scroll events. To fix this we need to make sure native and JS have the child frames in sync.
Summary:
Remove layout-only views. Works by checking properties against a list of known properties that only affect layout. The `RCTShadowView` hierarchy still has a 1:1 correlation with the JS nodes.
This works by adjusting the tags and indices in `manageChildren`. For example, if JS told us to insert tag 1 at index 0 and tag 1 is layout-only with children whose tags are 2 and 3, we adjust it so we insert tags 2 and 3 at indices 0 and 1. This keeps changes out of `RCTView` and `RCTScrollView`. In order to simplify this logic, view moves are now processed as view removals followed by additions. A move from index 0 to 1 is recorded as a removal of view at indices 0 and 1 and an insertion of tags 1 and 2 at indices 0 and 1. Of course, the remaining indices have to be offset to take account for this.
The `collapsible` attribute is a bit of a hack to force `RCTScrollView` to always have one child. This was easier than rethinking out the logic there, but we could change this later.
Summary:
@tadeuzagallo - We discussed this ~a week ago when I was putting together the 0.7.0-rc release, only got around to creating the PR for it now so it's properly sync'd.

Summary:
No longer check for the `ASIdentifierManager` class. Since we only target iOS 7.0 and up, this is unnecessary. Instead, we should check for whether the `advertisingIdentifier` is non-nil. If it is, we send it; otherwise we send an error.
Summary:
If you try to create a cached response from a nil response the app will crash. Looking at the code that uses NSURLSession and NSURLCache, this fix looks correct to me.

Summary:
@public
The API and implementation of `shouldInjectAJAXHandler` is very opinionated, and it does not solve many of the use cases that we'd like to address.
Since `shouldInjectAJAXHandler` is basically juts injecting JS to the web page, we should let developer inject whatever JS that address different issues that they want to fix.
Test Plan:
Test this snippet at <Playground />
```
<WebView
url="http://www.facebook.com"
injectedJavascriptIOS="document.body.style.border='solid 10px red'"
/>
```
