lavu: add av_usleep() function This function implements a delay using the first available of the following functions: - nanosleep() - usleep() - Sleep() (Windows) The conditional #includes in time.c are simplified by including unistd.h and windows.h whenever they are available rather than having these lines triggered by specific functions.
