Summary:
Looking to address a few new `FlowFixMe`s I had to do some minor refactoring of `MessageQueue`. Has the advantage of (IMO) making things clearer by removing a redundant counter and some gratuitous bitwise operations.
Previously `_callbacks` was an array of `?Function`s where even elements were failure callbacks and odd elements were successes. Each new call incremented `_callID` by one and `_callbackID` by two. I've changed this to use two arrays `_successCallbacks` and `_failureCallbacks` indexed by `callID`. That made the `_callbackID` counter unnecessary and reduced the need for computed indices.
Tested with flow and a quick play with UIExplorer.

Summary:
The stall watchdog is handy to detect stalls, but it doesn't really tell us what was
happening. This diff makes it easy to track React perf and bridge traffic during any stall, and
prints it out if the stall exceeds the threshold.
