Added support for clang thread-safety analysis
The annotations have been added to SDL_mutex.h and have been made public so applications can enable this for their own code.
Clang assumes that locking and unlocking can't fail, but SDL has the concept of a NULL mutex, so the mutex functions have been changed not to report errors if a mutex hasn't been initialized. We do have mutexes that might be accessed when they are NULL, notably in the event system, so this is an important change.
This commit cleans up a bunch of rare race conditions in the joystick and game controller code so now everything should be completely protected by the joystick lock.
To test this, change the compiler to "clang -Wthread-safety -Werror=thread-safety -DSDL_THREAD_SAFETY_ANALYSIS"

os2: SDL_DestroyMutex should ignore NULL mutexes.
Every other backend does this, so this should match, now.
It's possible this was harmless, but we can avoid the system call
and the (likely?) debug message when it fails, though!

os2: a _lot_ of coding style cleanup, sot that they match the SDL style.
also renamed the 'debug' macro to debug_os2: the former was dangerously
a common name.
the binary (dll) output is precisely the same as before.

os2: updates to SDL_systhread.c:
