Instead of parsing the ASS file in demux_libass.c and trying to pass the ASS_Track to the subtitle renderer, just read all file data in demux_libass.c, and let the subtitle renderer pass the file contents to ass_process_codec_private(). (This happens to parse full files too.) Makes the code simpler, though it also relies harder on the (messy) probe logic in demux_libass.c.
