I added a new flag RunningCB to know if the Fuzzer's main thread is running the CB function, instead of using (!CurrentUnitSize). (!CurrentUnitSize) doesn't work properly. For example, in FuzzerLoop.cpp, inside ShuffleAndMinimize() function, we execute the callback with an empty string (size=0). Previous implementation failed to detect timeouts in that execution. Also, I add a regression test for that case.
