Fixed bug 3930 - Android, set thread priorities and names

Browse Source 
SDLActivity thread priority is unchanged, by default -10 (THREAD_PRIORITY_VIDEO).

SDLAudio thread priority was -4 (SDL_SetThreadPriority was ignored) and is now -16 (THREAD_PRIORITY_AUDIO).

SDLThread thread priority was 0 (THREAD_PRIORITY_DEFAULT) and is -4 (THREAD_PRIORITY_DISPLAY).
