dvdplayer: resample/dup improvement

This merge request tries to improve the old resampling/dup/skip code in dvd player audio to better swing in to a state that is synchronous with the clock.

It limits the maximum resampling rate to 20% and re-uses sampling rate adjustment for the drop/dup code.

It drops the old output pts code that is not needed since we don't have stream discontinuities at thus stage.
