Summary:
Adds support for JS async methods and helps guide people writing native modules w.r.t. the callbacks. With this diff, on the native side you write:
```objc
RCT_EXPORT_METHOD(getValueAsync:(NSString *)key
resolver:(RCTPromiseResolver)resolve
rejecter:(RCTPromiseRejecter)reject)
{
NSError *error = nil;
id value = [_nativeDataStore valueForKey:key error:&error];
// "resolve" and "reject" are automatically defined blocks that take
// any object (nil is OK) and an NSError, respectively
if (!error) {
resolve(value);
} else {
reject(error);
}
}
```
On the JS side, you can write:
```js
var {DemoDataStore} = require('react-native').NativeModules;
DemoDataStore.getValueAsync('sample-key').then((value) => {
console.log('Got:', value);
}, (error) => {
console.error(error);
// "error" is an Error object whose message is the NSError's description.
// The NSError's code and domain are also set, and the native trace i

Summary:
`mountSafeCallback` simply wraps a callback in an `isMounted()` check to prevent crashes when old callbacks are called on unmounted components.
@public
Test Plan:
Added logging and made sure callbacks were getting called through
`mountSafeCallback` and that things worked (e.g. photo viewer rotation etc).
Summary:
Add `AlertIOS.prompt`
It's compatible with the js spec, with the exception that I had to add
a callback param since it's async. Also supports the same button configuration
as `AlertIOS.alert`.
@public
Test Plan:
I've updated the `AlertIOS` example on UIExplorer with every
valid combination of
parameters, so just going through it should be fine.
Summary:
The curly braces seems to be redundant.

Test Plan: Imported from GitHub, without a `Test Plan:` line.
Summary:
As it was implemented, the jsdoc parser would look only the first non-blank line immediately preceding a function declaration. However, the line that was set as the beginning of a function declaration was where the opening bracket (`{`) was. This is insufficient for functions whose definitions span multiple lines. For example, this declaration would not find the comments above it:
```
/**
* Clones rows
**/
cloneWithRows(
dataBlob: Array<any> | {[key: string]: any},
rowIdentities: ?Array<string>
): ListViewDataSource {
...
}
```
With this change, the parser will first check if we have a closing parenthesis. If we do and don't have a matching open parenthesis we continue moving up the lines until we find it. Then we set previous line to be the line before that, the true beginning of the function declaration.
