Summary:
This diff adds support for enforcing nullability in the arguments for exported methods.
We previously supported use of the nullable/nonnull attributes on method arguments, but didn't do anything to ensure that they were respected.
Now, if an argument is marked as nonnull, and a null value is sent for that argument, it will display a redbox.
In future, nonnull will be assumed by default, but for now we assume that un-annotated arguments can be null (to avoid breaking existing code).
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.

Include stack traces in native redboxes (e.g. from RCTLogError). It's not trivial to get the file names and line numbers for every frame of the stack, but we can get the first one which is nice.
Test Plan: {F22548418}

This probably needs more thought - might want to differentiate between console.error and reportError.
Test Plan: console.error and reportError no longer redbox. invariant and RCTLogError still do.

@public
There have been multiple instances of confusion about whether a redbox means the
developer did something they shouldn't but things will keep working, or if
something went horribly wrong and the app will crash in prod. This diff
introduces an orange background color to the redbox for `console.error` and
`RCTLogError` to indicate that something bad happened, but that the app will
continue working.
Test Plan:
see orange error for geo permissions:

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)
