Ftp-proxy in NPF

Got a note from one of the netbsd users/devs in an old mail thread.

Just looked at the ftp-proxy code. And 

ftp-proxy (initializes pf and starts the daemon.)
ftp-proxy -N (initializes npf and starts the daemon) (not updated in manual yet) 

Since we want to use npf as our primary packet filter, 

I want to resverse it. 

ftp-proxy (initialize npf and starts daemon.)
ftp-proxy -pf (initializes pf and starts daemon). 

And then include a small npf grammar in npf.conf to use ftp-proxy. 

Ftp-proxy code lives in dist/pf/usr.sbin. so tightly coupled with pf.
Want to relocate to ./usr.sbin/
