* modules/mux/mpeg/ts.c: reworked muxing of subtitles ES. 

* modules/stream_out/transcode.c: support for subtitles transcoding.
* modules/codec/dvbsub.c: DVB subtitles encoder (developed for Anevia, www.anevia.com).
  + only works on YUVP subpictures for now.
  + not completely spec compliant yet.
