My plan about that was this: introduce a new CodecID for the unprocessed ASS
packets (in the same format as they are in Matroska), use
AVFormatContext.subtitle_codec_id to allow applications to select the new
CodecID if they can handle it, and make it the default after some time.

Before that, there is another tidbit necessary: allow to set
AVFMT_TS_NONSTRICT on a per-stream basis, and set it for ASS streams.
