ffplay: add get_master_sync_type function
...
The real av_sync_type may be different to VideoState->av_sync_type, because the
required audio or video stream for audio or video clock may not be available.
We will use a function to query the real av_sync_type which is used for
determining the master clock.

ffplay: fix external time sync mode

We now initalize the external clock to 0 and, we use the system clock to
regulate the timings of audio and video in external clock sync mode. We
recover from external clock sync loss, when the delay to external clock is
bigger than AV_NOSYNC_THRESHOLD.

A decoded and resampled audio frame may not fit in the current size which is

ffplay: replace SDL_delay in read thread with SDL_CondWait
...
When the audio queue was empty, it was not filled until the 10ms delay expired
in the read thread. This patch changes the delay method with a condition wait,
which reacts to an empty queue a lot faster, therefore the audio buffer
underruns become less common especially after seeking.
