filter on prefixes

[fredrik danerklint]

I've made an patch for aggregate and saw this:

aggregate: [line 182241] 76.10.159.0/18 inconsistent; ignoring line

Now I think it's not birds fault complaing about the prefixes. Instead the 
routing information found in various databases is (totaly) wrong.  

Nothing to see here. Move along!
