make the pflog interface clonable.

for now, only allow pflog0 to be created.
keep an array of ifps to the pflog interfaces with the unit # as index for
fast access.
if pflog0 does not exist, no logging is done (just like if it is down).
on machines without pf enabled, this makes the pflog0 interface go away,
on machines with pf, rc sets up pflog0 and starts pflogd, no change there.
idea old (pf2k4 or c2k5?), hacked at the hack.lu 2006 conference, ryan ok
