  AVSync2: Fix never-ending stutter on Live TV

With AVSync2, Live TV could continue to stutter until pause
is pressed. Added a timecode reset so that it can add a small
delay to allow catch up.

  AVSync2: Improve resync speed and accuracy

1. If out of sync by more than 200 ms fix the sync more quickly.
2. Measure audio and video timecode at the same instant.
3. Base audio / video adjustment on the prior frame timecodes.
4. When there is excess audio (more than 200 ms) discard it.
5. No longer limit adjustments to when error is over 40 ms.

Fixes #13383
