Introduce the OpenBSD syntax of "scrub" option for "match" and "pass"
rules and the "set reassemble" flag. The patch is backward-compatible,
pf.conf can be still written in FreeBSD-style.

As for example pfctl -ss keeps calling it, it saves a lot of overhead
from elided parsing of /etc/nsswitch.conf and /etc/protocols.
Sample result when running a pre-nvlist binary with nfs root and dumping
7 mln states:

after: 8.064u 1.117s 0:18.87 48.5%

Track (and display) the interface that created a state, even if it's a
floating state (and thus uses virtual interface 'all').

When showing the states, in very verbose mode, also display the gateway
(i.e. the target for route-to/reply-to).

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
No functional change intended.
embedded structures out of a packed, unaligned struct into local copies
on the stack which are aligned.
The original patch to do this was submitted by Guy Yur <guyyur@gmail.com>,
and this is conceptually the same change, but restructured with the
#ifndef __NO_STRICT_ALIGNMENT wrapper, similar to how the same issue is
handled in the kernel pf code.

Original log:
pfctl -ss printed state levels for ICMPv6. Disable this the same
way it has already been done for ICMPv4.
Difference with OpenBSD:
- WITHOUT_INET6 safe

reside, and move there ipfw(4) and pf(4).
o Move most modified parts of pf out of contrib.
Actual movements:
sys/contrib/pf/net/*.c -> sys/netpfil/pf/
sys/contrib/pf/net/*.h -> sys/net/
contrib/pf/pfctl/*.c -> sbin/pfctl
contrib/pf/pfctl/*.h -> sbin/pfctl
contrib/pf/pfctl/pfctl.8 -> sbin/pfctl
contrib/pf/pfctl/*.4 -> share/man/man4
contrib/pf/pfctl/*.5 -> share/man/man5
sys/netinet/ipfw -> sys/netpfil/ipfw
The arguable movement is pf/net/*.h -> sys/net. There are
future plans to refactor pf includes, so I decided not to
break things twice.
Not modified bits of pf left in contrib: authpf, ftp-proxy,
tftp-proxy, pflogd.
The ipfw(4) movement is planned to be merged to stable/9,
to make head and stable match.
