add more audio passthru options

adds aac and mp3 passthru for mp4 and mkv containers
adds dts and dtshd for mp4 container (mkv already had it)
Note: The only player known (to me) to support dts(hd) in mp4 is ff/avplay

In LinGui there is a new option to limit which passthru codecs
will be used by the "Auto Passthru" audio codec options. The CLI
already has this ability with "--audio_copy-mask" which is use
in conjunction with the "copy" audio codec option.

Also corrects some A/V sync issues when video frames are dropped due to
a gap detected in the audio.
