When there's no explicit delivery system information for a channel in the channel configuration file and the user hasn't selected one via setting the delsys property, we *guessed* it by selecting the last supported delsys reported by the driver. This change provides the basis for smarter delsys auto detection and implements a rule for DVB-T2. Rules for other delivery systems can be added in _guess_delsys() in a similar way. Additionally: Store list of adapter-supported delivery systems instead of querying the driver each time this information is needed. Related to: https://bugzilla.gnome.org/show_bug.cgi?id=765731
