Summary: SDL_TryLockMutex blocks for pthreads with FAKE_RECURSIVE_MUTEX

Description Ian Abbott 2016-02-11 17:38:23 UTC 
I just spotted what I think is a bug in "src/thread/pthread/SDL_sysmutex.c" in the SDL_TryLockMutex function when FAKE_RECURSIVE_MUTEX is defined (for an implementation of Pthreads with no recursive mutex support).  It calls pthread_mutex_lock instead of pthread_mutex_trylock, so it will block until the mutex is available instead of returning SDL_MUTEX_TIMEDOUT if it cannot lock the mutex immediately.
