[PATCH] D27179: LibFuzzer - Implement timers for Windows and improve synchronization.

+ Move the interruption handler into a separate thread for Posix implemention (instead of asynchronous signal handler). This is more appropriate for 2 reasons:

- `InterruptCallback()` uses functions like printf, and accesses to global data, which is not appropriate for a signal handler. By using a separate thread, we are able to synchronize with the main thread.
- Is the same approach than Windows, which makes code simpler, since we are sure that `InterruptCallback()` will be excecuted in a separate thread in both Windows and Posix systems.

+ Improve Signal Handler interface (`FuzzerUtil*.cpp` files).
