dvb/si: add the TTML subtitling descriptor

Extension descriptor 0x20 of ETSI EN 303 560, which signals a DVB TTML
subtitle stream in the PMT: language, subtitle purpose, text-to-speech
suitability, the TTML processor profiles the stream conforms to, and the
optional presentation qualifier.

Only the profile list sits at a fixed offset; the qualifier, the essential
font list and the service description text each move with a count read out of
the descriptor, so validate() walks them rather than checking a single length.
