 The german provider Premiere and maybe other providers have special
 channels for PPV or sport events. On certified receivers you have an
 option key to reach these subevents like different camera perspectives in
 formula one events or the different movies on dynamic channels.
 This patch reads the linkage descriptors in the epg stream and writes the
 information to a special table. The Frontend reads the table when access
 the osd menu and insert an entry "subchannel" if the tuned channel is part
 of a linkage. The subchannel entry has subentries to each linked event and
 you can switch to all subevents from the menu.
 Note, that subentries were only created for events that have a valid epg
 entry in the program table.

 At the moment I didn't like how to show the subevents. I'd like to have
 some more information per event, like start or endtime, but I don't know
 how to realize it. Therefore a double line menu entry is needed.
 Maybe the best way were to put the info in an own treemenu that fills the
 screen horizontal.
 Comments are welcome.

 This patch is only tested with the german provider Premiere. Please
 provide me infos how it works on other providers. Maybe the store function
 must be restrict to a special linkage type. Premiere uses user_defined
 0xb0 as type.
