[PATCH] knfsd: define new nfsdfs file: portlist - contains list of ports

Browse source 
This file will list all ports that nfsd has open.
Default when TCP enabled will be
   ipv4 udp 0.0.0.0 2049
   ipv4 tcp 0.0.0.0 2049

Later, the list of ports will be settable.

'portlist' chosen rather than 'ports', to avoid unnecessary confusion with
non-mainline patches which created 'ports' with different semantics.
