BIRD show bgp summary for cli

[Milan Strakoš]

Hello,

I provide a patch for bird version 2, which is based on the patch for 
version 1 and displays imported, exported, preferred and filtered 
prefixes (also for "show protocols"). I use this output also for 
parsing. The output formatting can be adjusted individually. I'm not a 
programmer, so maybe it could be done better.

Nice holidays, Milan
