r11529
[dvbapi] Moved #define's to header file and made a few cosmetic changes
The CA PMT list management defined values are updated with proper info from the corresponding standard, instead of using OpenPLi's poor explanatory text.

r11528
[dvbapi] Moved parsing of CA descriptor to a separate function
This is necessary for the upcoming changes.

r11527
[dvbapi] Moved reading of priority entries in separate functions

r11526
[dvbapi] When parsing PAT, save found PMT pid in the demuxer
This way we can later start the PMT filter without explicitly passing the PMT pid.

r11525
[dvbapi] Changes to a couple of log messages

r11524
[dvbapi] Changed variable name (cosmetic)
dvbapi_parse_capmt() returns the demux_id, not the pmt_pid, so use a proper variable name.
