Summary:All UIManager operations that affect the view hierarchy are executed via the `addUIBlock:` method, which queues them up to be executed after layout has been completed on the shadow queue.
One of the most expensive view operations is view creation, but since this doesn't actually depend on layout, there's no reason to delay it until the shadow operations have finished.
This diff modifies the `createView` method to dispatch view creation directly to the main thread instead of adding it to the UIBlock queue. This seems to result a measurable improvement in TTI.

Summary:This works internally at FB but not here because mixed mode requires are mandatory. At FB www, only the providesModule version works. In React Core, we only use the providesModule name. I have to remember to change these back again when I do the move so that we can unify. 0f3bd02d0f

Summary:The website now displays public methods on components. This was implemented mostly in react-docgen via #66. This adds a <Method> component that is used by the component and API doc pages to display documentation for a method.
It also adds some missing documentation and tweak some existing one to integrate with this feature. I also prefixed some component methods with an '_' so they don't show up in the doc.
**Test plan (required)**
Tested every component page locally to make sure the methods doc was displayed properly.
Tested an API page to make sure it still worked properly.

Summary:This adds deprecation warnings that correspond to what React 0.14 did for the web.
I.e. `React.render` -> `ReactNative.render` but also `ReactNative.createClass` -> `React.createClass`.
This hopefully means that it will become easier and more idiomatic to write components that are decoupled from the react-native package.
It will be clear when you take on react-native as a dependency such as when using findNodeHandle.
This codemod is a little more invasive for React Native because the common stuff often used the `react-native` package. For web only the uncommon stuff needed to move.

Summary:First I searched for special cases that destructor PropTypes:
```
(?s)React\s*=\s*require\('react\-native'\).*(Children|PropTypes)[^\{\}]*\}\s*=\s*React;
```
I split them up manually.
Then I replaced the React = require('react-native') + destructuring pattern...
```
(?s)(const|var)\s+React\s*=\s*require\('react\-native'\)(.*[^\{\}]*\}\s*=\s*)React;
```
...with...
```
$1 React = require('react');
$1 ReactNative = require('react-native')$2ReactNative;
```
I used lint to figure out if I left some unnecessary imports.
Finally I grepped for just
```
React\s*=\s*require\('react\-native'\)
```
to catch any remaining patterns.
Also, `} = React.NativeModules` -> `} = ReactNative.NativeModules`.

Summary:On iOS, `WebView` will get stuck when the first request fails to load. The most common case where this could happen is when a user has limited or no connectivity.
Here's a repo with a sample app that demonstrates the problem and this fix: [https://github.com/jballer/react-native-webview-reload-example](https://github.com/jballer/react-native-webview-reload-example).
**Attempted workarounds**
- `WebView.reload()` fails internally because the `UIWebView`'s `currentRequest` doesn't have its `URL` set
- Setting `WebView.source.uri` won't do anything; the JS value value is unchanged and therefore doesn't cross the native bridge.
- Unmounting and remounting the `WebView` component would lose history and context if an error occurs on a request that's not the first request.
**Test plan (manual testing)**
1. Disable network connection
1. Relaunch application or reload JS
1. Enable network connection
1. Tap "reload" button
1. Observe whether page reloads

Summary:Since the React 0.14 split of modules, the findNodeHandle feature is part of the
renderer and not the generic React API.
This just greps for React.findNodeHandle and replace them with ReactNative.findNodeHandle. I fixed up the imports manually.
I also found two callers each of ReactNative.createClass and React.render with the exception of downstream and examples will fix them separately.
I'll need to find more things like `var { PropTypes } = ReactNative;` separately. I think this is a good start though.

Summary:This PR is to solve app build issue when node_modules is a symlink by providing an environmental variable to override the current *smart* guessing of app root path.
I met this issue when I tried to setup a shared incremental node_modules directory to speed our react-native app build speed in CI. But the build crashed in step 'bundleReleaseJsAndAssets' with error messages like:
> :app:bundleReleaseJsAndAssets
> bundle: Created ReactPackager
> uncaught error Error: NotFoundError: Cannot find entry file index.android.js in any of the roots:["/home/jenkins/shared_data"]
The build is fixed by applying this patch and adding 'export react_native_app_root=${WORKSPACE}' before './gradlew assembleRelease' in build script.
**Test plan**
1. react-native init demo # init a demo app from scratch
2. cd demo/android && ./gradlew assembleRelease # build works fine
3. mkdir ~/shared_data && mv ../node_modules ~/shared_data && cd .. && ln -s ~/shared_data/node_modules . # create symlink for node_modules in shared d
