- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

pflogd does not depend on libutil

Update packet filter (pf) code to OpenBSD 4.5.

You need to update userland (world and ports) tools
to be in sync with the kernel.

Append to CFLAGS, don't clobber it.

Add a ${.CURDIR} reference to the previous commit.

Force include ../../libpcap/config.h since privsep.c groks pcap's
internals.

Let pflogd's Makefile just use WARNS instead of changing CFLAGS.

This change allows me to disable -Werror by using NO_WERROR. Right now
I can't build pflogd using Clang, because Clang generates more warnings
when passing -Wall.

Fixed misspelling of DPADD.

Commit userland part of pf version 3.5 from OpenBSD (OPENBSD_3_5_BASE).

Add skeleton build dirs for pf userland:
libexec/ftp-proxy - ftp proxy for pf
sbin/pfctl - equivalent to sbin/ipf
sbin/pflogd - deamon logging packets via if_pflog in pcap format
usr.sbin/authpf - authentification shell to modify pf rulesets

Bring along some altq headers used to satisfy pfctl/authpf compile. This
helps to keep the diff down and will make it easy to have a altq-patchset
use the full powers of pf.

Also make sure that the pf headers are installed.

This does not link anything to the build. There will be a NO_PF switch for
make.conf once pf userland is linked.
