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.

Make OSD size per-OSD-object, as they can be different when using vf_sub. Include display_par/video_par in resolution change detection. Fix the issue with margin borders in vo_corevideo.

subs, vo: do sub bitmap change detection by comparing IDs vo_vdpau and vo_gl cache the last subtitle bitmaps uploaded to video card in case they stay the same over multiple frames. Detecting whether the bitmaps have changed and should be re-uploaded was somewhat fragile. Change the VO API to provide a bitmap ID which can be compared with what the VO has to determine whether a new upload of the bitmaps is needed. Conflicts: libvo/vo_gl.c Note: the changes for vo_gl.c were not merged. Instead, eosd_packer is modified to use the new way of detecting EOSD changes. This takes care of vo_gl, vo_gl3 and vo_direct3d, which all render EOSD. They don't need to be updated in turn.
