eaa7035b13 Shut up a couple of annoying gcc warnings. Do not enclose the fixes with 
#ifdefs in order to loop it back to OpenBSD after the next import. There are
a some implicit asserts involved which might be better spelled out
explicitly (af == AF_INET ...)

cf5011b74a Commit two fixes from OpenBSD's stable branch: 
- Fix binat for incoming connections when a netblock (not just a single
  address) is used for source in the binat rule. closes PR 3535, reported by
  Karl O.Pinc. ok henning@, cedric@

- Fix a problem related to empty anchor rulesets, which could cause a kernel
  panic.

cc7e902276 Style(9) round for the pf kernel parts. Mostly #if defined() -> #ifdef 
Also set HOOK_HACK to true (remove the related #ifdef's) as we have the
hooks in the kernel this was missed during the merge from the port.

Noticed by:	Amir S.	(for the HOOK_HACK part)

01315efca3 Remove __inline keyword from functions that can't be inlined according to 
LINT. This fixes LINT compliation for now, but needs to be revised.
Changes do not affect the objects.

cc5934f5af Tweak existing header and other build infrastructure to be able to build 
pf/pflog/pfsync as modules. Do not list them in NOTES or modules/Makefile
(i.e. do not connect it to any (automatic) builds - yet).

2bbe8ffc9d 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.
