Summary:
I encountered a crash when `RCTCurrentThreadName` called `dispatch_get_current_queue`. There are reports of it crashing e.g. https://github.com/CocoaLumberjack/CocoaLumberjack/issues/108 so better not to call it at all, plus it is deprecated.
Since we still want helpful debugging information, use `DISPATCH_CURRENT_QUEUE_LABEL` instead. It's kind of strange that this constant is defined to be NULL and the docs for `dispatch_get_queue_label` say not to pass in NULL, but in practice `DISPATCH_CURRENT_QUEUE_LABEL` is provided by the iOS SDK and works correctly.

Summary:
@public
I've increased the warning levels in the OSS frameworks, which caught a bunch of minor issues. I also fixed some new errors in Xcode 7 relating to designated initializers and TLS security.
Test Plan:
* Test the sample apps and make sure they still work.
* Run tests.
Summary:
@public
Add `RCTAssertThread` to `RCTAssert.h` for convenience when checking the current/queue,
it accepts either a `NSString *`, `NSThread *` or `dispatch_queue_t` as the object to be checked
Also add a check to `-[RCTUIManager addUIBlock:]` - There was a discussion on github (https://github.com/facebook/react-native/issues/1365)
due to the weird behavior caused by calling it from a different thread/queue (it might be added after `batchDidComplete` has been called
and will just be dispatched on the next call from JS to objc)
Test Plan:
Change `-[RCTAnimationExperimentalManager methodQueue]` to return `dispatch_get_main_queue()` and run the 2048 example,
it should dispatch with a helpful message (screenshot on the comments)
