Implement two new filters, max-as-len and max-as-seq. The first is limiting
the length of an AS path (matches if the path is longer then the specified
lenght) the second matches when a sequence of the same AS number is longer
then the specified length).
max-as-len is good to protect crappy comercial bgp boxes from other crappy
comercial bgp boxes. max-as-seq was a feature request from SwissIX and maybe
EuroIX to find and filter prepends.
Additinal testing and OK sthen@
