subtitles: add framework for subtitle decoders Add a framework for subtitle decoder modules that work more like audio/video decoders do, and change libass rendering of demuxed subtitles to use the new framework. The old subtitle code is messy, with details specific to handling particular subtitle types spread over high-level code. This should make it easier to clean things up and fix some bugs/limitations.

subs: always use sub decoder framework for libass rendering Remove subtitle selection code setting osd->ass_track directly and vf_ass/vf_vo code rendering the track directly with libass. Instead, do track selection and rendering with dec_sub.c functions. Before, mpctx->set_of_ass_tracks[] contained bare libass tracks generated from external subtitle files. For use with dec_sub.c, it now contains struct sh_sub instances with decoder already initialized. This commit breaks the sub_step command ('g' and 'y' keys) for libass-rendered subtitles. It could be fixed, but it's so useless - especially as with the existing implementation there's no practical way to get subtitle delay back to normal after using it - that I didn't bother. Conflicts: command.c mp_core.h mplayer.c

struct sd_functions {
sd_lavc: use subtitle framework for former av_sub.c code Change libavcodec subtitle decoding code (used for some bitmap subtitle types) to use the same decoding framework as sd_ass. The functionality that was previously in av_sub.c and was directly called from mplayer.c is now in sd_lavc.c. Conflicts: mplayer.c sub/av_sub.h sub/sd_lavc.c Merged from mplayer2. The remaining use of is_av_sub() is replaced by a check whether a subtitle decoder is active, which should give the same results.
