Summary:

Blending semitransparent pixels against their background is fairly a fairly expensive operation on mobile GPUs. To reduce blending, React Native has a system called "background color propagation", where the background color of parent views is automatically inherited by child views unless explicitly overridden. This means that translucent pixels can be blended directly against a known background color, avoiding the need to do this dynamically on the GPU.
In practice, this is only useful for views that do their own drawing, which is basically just `<Image/>` and `<Text/>` components, and for image components it only really matters when the image has an alpha component.
The automatic background propagation is a bit of a hack, and often does the wrong thing - for example if a view overflows its bounds, or if it overlaps a sibling, the background color will often be incorrect and need to be manually disabled. Because the only place that it provides a significant performance benefit is for text, this diff disables the behavior for everything except `<Text/>` nodes. It might still be useful for `<Image/>` nodes too, but looking through the examples in UIExplorer, the number of places where it does the wrong thing for images outnumbers the cases where it provides significant reduction in blending.
Note that this diff does not prevent you from eliminating blending on image components by manually setting an opaque background color, nor does it stop you from disabling color propagation on text components by manually setting a transparent background.

Summary:
An HTTP request may be redirected to another URL, sometimes we need to know the URL where the response comes from.
If the server is in control, we can add an HTTP header X-Request-URL for the redirect URL. However there will be cases that 3rd party services are used.
This PR retrieves the response URL from native networking module and passes to it XMLHttpRequest. The fetch API built on XMLHttpRequest also benefits from this feature.

Summary:
Current default value of ProgressBarAndroid's styleAttr is "Large" which sets the ProgressBar's style to [Widget_ProgressBar_Large](http://developer.android.com/reference/android/R.style.html#Widget_ProgressBar_Large) at native side. But large is not the default style for the native side ProgressBar.
For example, the size of the ProgressBar is 48dip for default style, but 76dip for large and 16dip for small as in the Material themes. Although the size of ProgressBarAndroid could be set in JS, it'll be better to have the same default style as in native side themes.
My PR adds a "Normal" value for styleAttr prop and makes it the default value.

Calling navigator.replace(0, scene) has no effect.
This is because 0 is false in Javascript so when

(meaning update all indices starting with 0)
The whole expression evaluates to 0, i.e. false -> therefore no update
happens.
Explicitly checking for not-equal to null (!= will convert undefined to null automatically) fixes the issue.

However, if you don't have the entitlement, the app store warns you when you push an app build that contains `application:didRegisterForRemoteNotificationsWithDeviceToken:`, even if it isn't being called. This renames the methods so they have different names from the ones on UIApplication so the app store doesn't warn about them.

Summary:
Both iOS and Android currently support some sort of native pull to refresh control but the API was very different. I tried implementing a component based on PullToRefreshViewAndroid but that works on both platforms.
I liked the idea of wrapping the ListView or ScrollView with the PullToRefreshView component and allow styling the refresh view with platform specific props if needed. I also like the fact that 'refreshing' is a controlled prop so there is no need to keep a ref to the component or to the stopRefreshing function.
It is a pretty rough start so I'm looking for feedback and ideas to improve on the API before cleaning up everything.
On iOS we could probably deprecate the onRefreshStart property of the ScrollView and implement the native stuff in a PullToRefreshViewManager. We could then add props to customize the look of the UIRefreshControl (tintColor). We could also deprecate the Android only component and remove it later.

This diff adds a `getSize()` method to `Image` to retrieve the width and height of an image prior to displaying it. This is useful when working with images from uncontrolled sources, and has been a much-requested feature.
In order to retrieve the image dimensions, the image may first need to be loaded or downloaded, after which it will be cached. This means that in principle you could use this method to preload images, however it is not optimized for that purpose, and may in future be implemented in a way that does not fully load/download the image data.
A fully supported way to preload images will be provided in a future diff.
The API (separate success and failure callbacks) is far from ideal, but until we agree on a unified standard, this was the most conventional way I could think of to implement it. If it returned a promise or something similar, it would be unique among all such APIS in the framework.
Please note that this has been a long time coming, in part due to much bikeshedding about what the API should look like, so while it's not unlikely that the API may change in future, I think having *some* way to do this is better than waiting until we can define the "perfect" way.

Summary:
We don't (yet) treat these the same as any other modules because we still have special resolution rules for them in the packager allowing the use of `providesModule`, but I believe this allows people to use npm react in their RN projects and not have duplicate copies of React. Fixesfacebook/react-native#2985.
This relies on fbjs 0.6, which includes `.flow` files alongside the `.js` files to allow them to be typechecked without additional configuration. This also uses react 0.14.5, which shims a couple of files (as `.native.js`) to avoid DOM-specific bits. Once we fix these in React, we will use the same code on web and native. Hopefully we can also remove the packager support I'm adding here for `.native.js`.
This diff is not the desired end state for us – ideally the packager would know nothing of react or fbjs, and we'll get there eventually by not relying on `providesModule` in order to load react and fbjs modules. (fbjs change posted here but not merged yet: https://github.com/facebook/fbjs/pull/84.)
This should also allow relay to work seamlessly with RN, but I haven't verified this.

Implement all the necessary glue code for several diffs submitted before to get Hot Loading work end to end:
- Simplify `HMRClient`: we don't need to make it stateful allowing to enable and disable it because both when we enable and disable the interface we need to reload the bundle.
- On the native side we introduced a singleton to process the bundle URL. This new class might alter the url to include the `hot` attribute. I'm not 100% sure this is the best way to implement this but we cannot use `CTLSettings` for this as it's are not available on oss and I didn't want to contaminate `RCTBridge` with something specific to hot loading. Also, we could potentially use this processor for other things in the future. Please let me know if you don't like this approach or you have a better idea :).
- Use this processor to alter the default bundle URL and request a `hot` bundle when hot loading is enabled. Also make sure to enable the HMR interface when the client activates it on the dev menu.
- Add packager `hot` option.
- Include gaeron's `react-transform` on Facebook's JS transformer.
The current implementation couples a bit React Native to this feature because `react-transform-hmr` is required on `InitializeJavaScriptAppEngine`. Ideally, the packager should accept an additional list of requires and include them on the bundle among all their dependencies. Note this is not the same as the option `runBeforeMainModule` as that one only adds a require to the provided module but doesn't include all the dependencies that module amy have that the entry point doesn't. I'll address this in a follow up task to enable asap hot loading (9536142)
I had to remove 2 `.babelrc` files from `react-proxy` and `react-deep-force-update`. There's an internal task for fixing the underlaying issue to avoid doing this horrible hack (t9515889).
