[nsp] NBAR, Gnutella and 'match protocol http url'

[Jim Dueltgen]

Sorry, that was perhaps misleading of me.  I'm using the "ip nbar 
port-map custom-xx" (xx can be 01 through 10) command to identify 
traffic from programs that aren't covered by the built-in PDLMs; 
things like eDonkey, BitTorrent, some gaming protocols, etc.  So, I 
guess one wouldn't call that a custom PDLM, just custom port maps 
within NBAR.
