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.

In pfctl_set_debug() we used 'level' without ever initialising it.
We correctly parsed the option, but them failed to actually assign the parsed
value to 'level' before performing to ioctl() to configure the debug level.

The crop/drop-ovl fragment scrub modes are not very useful and likely to confuse
users into making poor choices.
It's also a fairly large amount of complex code, so just remove the support
altogether.
Users who have 'scrub fragment crop|drop-ovl' in their pf configuration will be
implicitly converted to 'scrub fragment reassemble'.

CoDel is a parameterless queue discipline that handles variable bandwidth
and RTT.
It can be used as the single queue discipline on an interface or as a sub
discipline of existing queue disciplines such as PRIQ, CBQ, HFSC, FAIRQ.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

slightly edited during the pf(4) SMP project. It is about to be edited
more in the projects/ifnet. Moving out of contrib also allows to remove
several hacks to the make glue.

race prone. Some just gather statistics, but some are later used in
different calculations.
A real problem was the race provoked underflow of the states_cur counter
on a rule. Once it goes below zero, it wraps to UINT32_MAX. Later this
value is used in pf_state_expires() and any state created by this rule
is immediately expired.
Thus, make fields states_cur, states_tot and src_nodes of struct
pf_rule be counter(9)s.
Thanks to Dennis for providing me shell access to problematic box and
his help with reproducing, debugging and investigating the problem.

INET6 socket when needed to allow pfctl to work on noinet and noinet6
kernels (and try to provide a fallback using AF_LINK as best effort).
Adjust the Makefile to also respect relevant src.conf(5) options
for compile time decisions on INET and INET6 support.

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.
Discussed with: bz, luigi
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.
