sd_lavc, sd_spu: make dvdsub stretching conditional on --stretch-dvd-subs.
We found that the stretching - although it usually improves the looks of the fonts - is incorrect. On DVD, subtitles can cover the full area of the picture, and they have the same pixel aspect as the movie itself. Too bad many commercially released DVDs use bitmap fonts made with the wrong pixel aspect (i.e. assuming 1:1) - --stretch-dvd-subs will make these more pretty then.
