Nick Lockwood 9f48c004ba Added setChildren() function
Summary:
public
Most of the time - especially during app startup - when we call UIManager.manageChildren(), we are actually just adding the first set of children to a newly created view.

This case is already optimized for in the JS code, by memoizing index arrays at various sizes, but this is not especially efficient since it is still sending an array of indices with each call that could be easily inferred on the native side instead.

I've added a hybrid native/JS optimization that improves the performance for this case. It's not a huge win in terms of time saved, but benchmarks show improvements in the ~1% range for several of the app startup metrics.

Satyajit Sahoo eb188c8d98 Add deep linking support to IntentAndroid
Summary:
Add a method to handle URLs registered to the app,

```js
IntentAndroid.getInitialURL(url => {
    if (url) {
        // do stuff
    }
});
```

Refer - http://developer.android.com/training/app-indexing/deep-linking.html#adding-filters

The API cannot be same as the iOS API (i.e. as a constant), as the activity is not availble at the time of module initialization. Moreover, multiple activties can share the same bridge instance, and the activity itself is not a constant. Hence the initialURL can change.

Summary:
Closes #4290

`mostRecentEventCount` was always being set after `text` on iOS, so let's be really explicit about the order here as we were doing on Android: always call `setNativeProps` providing the `mostRecentEventCount` before we call `onChange` or `onChangeText`.

I also ripped out storing `mostRecentEventCount` in the state, which isn't necessary since we're always doing it through `setNativeProps`.

Leland Richardson 3eb32cbb0e Animated.multiply and Animated.add to combine animated values
Summary:
This PR was created in response to feedback from an older PR: https://github.com/facebook/react-native/pull/2045

The `.interpolate()` API of Animated values is quite effective to accomplish transformations based on a single animated value, but currently there is a class of animations that is impossible: animations being driven by more than one value.

Usage would be like the following:

```js
getInitialState: function() {
  return {
    panY: new Animated.Value(0),
    offset: new Animated.Value(0),
  };
}
```

```js
var scale = Animated.add(panY, offset).interpolate({
  inputRange: [...],
  outputRange: [...],
});
```

I have a real use case for this, and I cannot think of any way to accomplish what I need without an API like this.

The animation I am trying to accomplish is I have a PanResponder being used to detect both x and y panning. The y-axis panning drives a 3d sroll-like animation (which we can call `panY`), and the x-axis panning is driving a "swipe-to-remove" animation (

Summary:
public

This diff replaces the RegEx module method parser with a handwritten recursive descent parser that's faster and easier to maintain.

The new parser is ~8 times faster when tested on the UIManager.managerChildren() method, and uses ~1/10 as much RAM.

The new parser also supports lightweight generics, and is more tolerant of white space.

(This means that you now can – and should – use types like `NSArray<NSString *> *` for your exported properties and method arguments, instead of `NSStringArray`).

Sebastian Markbage 8d397b4cbc Decouple Module System from Native Calls
Summary:
The JavaScript ecosystem doesn't have the notion of a built-in native module loader. Even Node is decoupled from its module loader. The module loader system is just JS that runs on top of the global `process` object which has all the built-in goodies.

Additionally there is no such thing as a global require. That is something unique to our providesModule system. In other module systems such as node, every require is contextual. Even registered npm names are localized by version.

The only global namespace that is accessible to the host environment is the global object. Normally module systems attaches itself onto the hooks provided by the host environment on the global object.

Currently, we have two forms of dispatch that reaches directly into the module system. executeJSCall which reaches directly into require. Everything now calls through the BatchedBridge module (except one RCTLog edge case that I will fix). I propose that the executors calls directly onto `BatchedBridge` through an instance on the global so that everything is guaranteed to go through it. It becomes the main communication hub.

I also propose that we drop the dynamic requires inside of MessageQueue/BatchBridge and instead have the modules register themselves with the bridge.

executeJSCall was originally modeled after the XHP equivalent. The XHP equivalent was designed that way because the act of doing the call was the thing that defined a dependency on the module from the page. However, that is not how React Native works.

The JS side is driving the dependencies by virtue of requiring new modules and frameworks and the existence of dependencies is driven by the JS side, so this design doesn't make as much sense.

The main driver for this is to be able to introduce a new module system like Prepack's module system. However, it also unlocks the possibility to do dead module elimination even in our current module system. It is currently not possible because we don't know which module might be called from native.

Since the module system now becomes decoupled we could publish all our providesModule modules as npm/CommonJS modules using a rewrite script. That's what React Core does.

That way people could use any CommonJS bundler such as Webpack, Closure Compiler, Rollup or some new innovation to create a JS bundle.

This diff expands the executeJSCalls to the BatchedBridge's three individual pieces to make them first class instead of being dynamic. This removes one layer of abstraction. Hopefully we can also remove more of the things that register themselves with the BatchedBridge (various EventEmitters) and instead have everything go through the public protocol. ReactMethod/RCT_EXPORT_METHOD.

This diff introduces a new RCTImageSource class which can be used to pass image source objects over the bridge and defer loading until later.

I've also added automatic application of the `resolveAssetSource()` function based on prop type, and fixed up the image logic in NavigatorIOS and TabBarIOS.

Nick Lockwood f9b744d501 Use lazy getters to reduce `require('react-native')` overhead
Summary:
public

In the open source React Native implementation, the recommended approach for importing modules is by importing a the `ReactNative` object, which includes all available modules.

This is rather inefficient because it ends up initializing all the JS modules, even if you don't use them.

This diff switches the properties of the `ReactNative ` object to lazy getter functions, which defers the `require` until the module is actually requested.

This doesn't prevent unused modules from being included in the JS bundle, but it will prevent them from being initialized unless/until they are used.

Matt Revell c1849e7f4b Fix an issue with unsafe picker access to setNativeProps.

Fixing an issue where PickerIOS and DatePicker are being accessed unsafely, As a side effect we are also using ref callbacks as oppose to strings.
