wang-bin 5af055a729 clear audio output buffer after seek 
if old audio data is playing, when send new data to ao, clock update use
the old timestamp which is wrong

wang-bin af0df77701 avsync: improve sync after seek 
sometimes video thread seek finished but audio thread seek is not
started. so if video thread start to take a packet, the av time diff can
be large, and video thread may drop frames until the next key frame. The
solution is wait all threads finish the seek. For some reasons I didn't
do it. But seems no better solution. New apis in AVClock is used
internally. Maybe we can add class to manage avsync and keep the clock
clean.

wang-bin 92f42de7e5 fix avsync after seek if last packet decode failed 
Will not take seek packet until the last packet is decoded successfully.
So audio clock is wrong and results in bad sync

wang-bin 097bb915e2 ao: software volume control 
Previous volume control was in AudioThread. Thas not reasonable because
user must use AVPlayer. Now audio samples are scaled in AudioOutput.
Also scale function is updated less.

control or set by user), use backend implemention

wang-bin fbd94ee12f avoid out of sync after seek 
before pakcet queue.clear(), a/v thread may takes 1 packet and
later compares to new packets after seek. the diff will be large. just
ignore once
when seeking, can not contunue without decoding video.

wang-bin f867ccafd8 show the first frame after seek on pause. 1.4.1 regression. issue325 
the way of seeking was changed after 1.4.0 to avoid frequent seek
request better. old seeking solution is ugly using a timer. but new
code result in no video frame update after seek on pause.
