Bring diff from the security/pf port. This has code been tested as a port
for a long time and is run in production use. This is the code present in
portversion 2.03 with some additional tweaks.

The rather extensive diff accounts for:
 - locking (to enable pf to work with a giant-free netstack)
 - byte order difference between OpenBSD and FreeBSD for ip_len/ip_off
 - conversion from pool(9) to zone(9)
 - api differences etc.
