branches: 1.3.2;
make PF lkm working. from Peter Postma and Joel Wilsson.

remove pf_ioctl_head/pf_newif_head, which was never used.

PF from openbsd 3.5. missing features:
- pfsync (due to protocol # assignment issues)
- carp (not really a PF portion, but thought important to mention)
- PF and ALTQ are mutually-exclusive. this will be sorted out when
kjc@csl.sony.co.jp updates ALTQ and PF (and API inbetween)
