Make OS specific timer code export a mp_raw_time_us() function, and add generic implementations of GetTimer()/GetTimerMS() using this function. New mpv code is supposed to call mp_time_us() in situations where precision is absolutely needed, or mp_time_s() otherwise. Make it so that mp_time_us() will return a value near program start. We don't set it to 0 though to avoid confusion with relative vs. absolute time. Instead, pick an arbitrary offset. Move the test program in timer-darwin.c to timer.c, and modify it to work with the generic timer functions.
