* Improve autogen for reference docs including jsdoc support
Summary:
As part of improving the API and Component reference docs #8154 this pull request adds the following:
- jsdoc support for API docs. See the AlertIOS changes as an example.
- type definitions support and added to both API and Component docs. This is supported via react-docgen and jsdoc.
- better formatting of method properties (now shown in a table).
FYI, API and Component docs were previously generated in two different ways. Components were using react-docgen and that basically remains as-is. APIs were using custom parsing code and that's been switched to use a jsdoc parser + react-docgen as an option for typedefs (it could also use the jsdoc parser).
Two docs have been updated to showcase how we'd like the new docs to look:
- AlertIOS (API): showing method parameters, examples, typedefs, more details overall.
- Statusbar (Component): showing method parameters, typedefs, more details overall.
**Note**: To convert new API docs to use the new format, add `jsdoc` to the initial file comment. C

* Add react-native-web-player to core components docs
Summary:
This PR adds the interactive [React Native Web Player](http://dabbott.github.io/react-native-web-player/) to the docs. The web player is an embeddable iframe which runs React Native code using components from [react-native-web](https://github.com/necolas/react-native-web). For now, it's primarily for educational purposes, since only the basic components are implemented.
Some details:
- The iframe is loaded from MaxCDN using rawgit, locked down to a git tag.
- Asset paths (i.e. images) are resolved relative to `//facebook.github.io/react-native/`
- When viewed on mobile, it falls back to the syntax-highlighted code blocks.
The WebPlayer can be inserted into markdown by using the fences:
```
```ReactNativeWebPlayer

AppRegistry.registerComponent ...

Summary:
This adds support for specifying multiple sources for an image component, so that native can choose the best one based on the flexbox-computed size of the image.
The API is as follows: the image component receives in the `source` prop an array of objects of the type `{uri, width, height}`. On the native side, the native component will wait for the layout pass to receive the width and height of the image, and then parse the array to find the best fitting one. For now, this does not support local resources, but it will be added soon.
To see how this works and play with it, there's an example called `MultipleSourcesExample` under `ImageExample` In UIExplorer.

Summary:
Under rare and as-yet-to-be determined circumstances, images can sometimes fail to load/download and get "stuck", without producing an error.
Because the `RCTNetworkTask` for these images is stuck in the "in progress" state, they clog up the RCTImageLoader task queue, which has a limit of 4 concurrent in-progress tasks.
This was previously masked by the fact that we automatically cancelled image requests when the RCTImageView moved offscreen, but we no longer do that.
This diff adds logic to detect some types of stuck task and remove them, thereby unblocking the queue. I've also restored the functionality of cancelling downloads for offscreen images (but not unloading the image itself) so that stuck images will be cancelled when you move to another screen, instead of using up space in the queue forever.

This diff replaces the `NSThread.isMainQueue` checks with dispatch_get_specific(), which is the recommended approach.
I've also replaced all use of "MainThread" terminology with "MainQueue", and taken the opportunity to deprecate the "sync" param of `RCTExecuteOnMainThread()`, which, while we do still use it in a few places, is incredibly unsafe and shouldn't be encouraged.

Summary:
Allows developers to specify headers to include in the HTTP request
when fetching a remote image. For example, one might leverage this
when fetching an image from an endpoint that requires authentication:
```
<Image
style={styles.logo}
source={{
uri: 'http://facebook.github.io/react/img/logo_og.png',
headers: {
Authorization: 'someAuthToken'
}
}}
/>
```
Note that the header values must be strings.
Works on iOS and Android.
**Test plan (required)**
- Ran a small example like the one above on iOS and Android and ensured the headers were sent to the server.
- Ran a small example to ensure that \<Image\> components without headers still work.
- Currently using this code in our app.

Summary:
Previously, only Text and Image could be nested within Text. Now, any
view can be nested within Text. One restriction of this feature is
that developers must give inline views a width and a height via
the style prop.
Previously, inline Images were supported by using iOS's built-in support
for rendering images with an NSAttributedString via NSTextAttachment.
However, NSAttributedString doesn't support rendering arbitrary views.
This change adds support for nesting views within Text by creating one
NSTextAttachment per inline view. The NSTextAttachments act as placeholders.
They are set to be the size of the corresponding view. After the text is
laid out, we query the text system to find out where it has positioned each
NSTextAttachment. We then position the views to be at those locations.

Summary:
Some apps are complaining about flashing images when performing navigation transitions. An example issue would be:
1. Load a master list view with many images
2. Click on an image to go to a detail view
3. Go back to the master list view
At step (3), users see a number of images flash from a placeholder image back to the final image because `-[RCTImageView didMoveToWindow]` calls `clearImage` when the image view exits the view hierarchy between (1) and (2) and calls `reloadImage` (which sets the image property asynchronously) when the image view re-enters the view hiearchy between (2) and (3).
This diff fixes the issue by being less aggressive about clearing image contents. It only clears image contents when the app receives a memory warning or the app goes into the background.
For comparison, CKNetworkImageComponent in ComponentKit doesn't have this purging behavior at all.

Summary:
In RN we cache image data after loading/downloading an image, however the data we store is the compressed image data, and we decode this asynchronously each time it is displayed.
This can lead to a slight flicker when reloading image components because the decoded image is discarded and then re-decoded.
This diff adds a small (5MB) cache for decoded images so that images that are currently on screen shouldn't flicker any more if the component is reloaded.

Summary:
This works with D3305161 to minimize image flashing. After D3305161, the completion handler passed to `-[RCTImageLoader loadImageWithoutClipping:size:scale:resizeMode:progressBlock:completionBlock:]` may be called back on the main queue in the case of a cached image. In this case, we want to set the image view's image property synchronously rather than on the next runloop iteration via dispatch_async. This minimizes the amount of image flashing the user sees when displaying a cached image.
The exception to this case is for blurred images. A blur can be an expensive (taking multiple ms on the CPU), so we always make sure to perform the blur off the main queue even if the image is cached and the callback came back on the main queue.

Summary:
public
React Native currently exposes the iOS layer shadow properties more-or-less directly, however there are a number of problems with this:
1) Performance when using these properties is poor by default. That's because iOS calculates the shadow by getting the exact pixel mask of the view, including any tranlucent content, and all of its subviews, which is very CPU and GPU-intensive.
2) The iOS shadow properties do not match the syntax or semantics of the CSS box-shadow standard, and are unlikely to be possible to implement on Android.
3) We don't expose the `layer.shadowPath` property, which is crucial to getting good performance out of layer shadows.
This diff solves problem number 1) by implementing a default `shadowPath` that matches the view border for views with an opaque background. This improves the performance of shadows by optimizing for the common usage case. I've also reinstated background color propagation for views which have shadow props - this should help ensure that this best-case scenario occurs more often.
For views with an explicit transparent background, the shadow will continue to work as it did before ( `shadowPath` will be left unset, and the shadow will be derived exactly from the pixels of the view and its subviews). This is the worst-case path for performance, however, so you should avoid it unless absolutely necessary. **Support for this may be disabled by default in future, or dropped altogether.**
For translucent images, it is suggested that you bake the shadow into the image itself, or use another mechanism to pre-generate the shadow. For text shadows, you should use the textShadow properties, which work cross-platform and have much better performance.
Problem number 2) will be solved in a future diff, possibly by renaming the iOS shadowXXX properties to boxShadowXXX, and changing the syntax and semantics to match the CSS standards.
Problem number 3) is now mostly moot, since we generate the shadowPath automatically. In future, we may provide an iOS-specific prop to set the path explicitly if there's a demand for more precise control of the shadow.
