dvb: Extend understanding of VDR channel config: stream_id, inversion.
Now also "stream ID" (for DVB-S2) and "inversion" are understood. The parameter-string can also provide information on FEC, rolloff etc. For DVB-S, "auto" which mpv uses by default should be fine, I can also confirm it works. For non-DVB-S cards, it might be useful to also parse this information in case of a vdr-channel list. As I have no such hardware and thus would have to do it blindly, I added a FIXME. Mostly complete vdr-channels.conf format documentation is at http://www.vdr-wiki.de/wiki/index.php/Channels.conf (german only).
