DTV: scan based on NIT infos

NIT of a DVB streams contain additionnal data (currently playing, next, ...)

We need to get these

changed milestone to %0.8.5-final

added 1 deleted label

changed milestone to %Features paradize

Current/Next is stored in EIT and we allready get those. NIT is only useful to find which other frequencies there are transponders on, so only useful for scanning apps. Would be a lot more constructive to add parser support for channel lists from other scan apps than to add a dvb scanner to vlc.

added Status::invalid label

closed

added Component::Services discovery Version::master git labels and removed Status::invalid label

reopened

changed title from Get DVB info in NIT to DTV: scan based on NIT infos

that would be useful if founded transponders can be added to playlist with all services as (-)children of particular tranponder...

older dvbsnoop example:

DVB-DescriptorTag: 67 (0x43)  [= satellite_delivery_system_descriptor]
        Descriptor_length: 11 (0x0b)
        Frequency: 18323280 (=  11.79750 GHz)
        Orbital_position: 402 (=  19.2)
        West_East_flag: 1 (0x01)  [= EAST]
        Polarisation: 0 (0x00)  [= linear - horizontal]
        Modulation (Sat): 1 (0x01)  [= QPSK]
        Symbol_rate: 2576384 (=  27.5000)
        FEC_inner: 3 (0x03)  [= 3/4 conv. code rate]
