  Playback: AvSync2 fix fast forward/rewind

Fast forward and rewind were not handling frame timing correctly so that
they were dropping frames, resulting in no frames displayed in some cases.

  AVSync2: Use frame timestamps to determine elapsed play time

MythTV uses frame count to determine the elapsed time of a recording
for display, jumps, etc. This can be inaccurate with variable rate
content and also with frame doubling being done in the decoder.
This change recalculates the frame count based on the time code.
This ensures MythTV elapsed time will be accurate.

Fixes #13416

  Playback: Improve "Music Choice" detection

Some recordings could be incorrectly detected as "Music Choice",
resulting in audio-video sync problems. This improves detection to
reduce the likelihood of that.
