0cd7a91aa7 pfctl: Allow TOS bits to be cleared
TOS value 0 is valid, so use 256 as an invalid value rather than zero.
This allows users to enforce TOS == 0 with pf.

3e248e0fb4 pf: Filter on and set vlan PCP values
Adopt the OpenBSD syntax for setting and filtering on VLAN PCP values. This
introduces two new keywords: 'set prio' to set the PCP value, and 'prio' to
filter on it.

1cac26262e Make pfctl(8) work on strict-alignment platforms, by copying a pair of
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.

3e768368d0 pfctl: Fix uninitialised veriable
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.

64b3b4d611 pf: Remove support for 'scrub fragment crop|drop-ovl'
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'.

0a70aaf8f5 Add ALTQ(9) support for the CoDel algorithm.
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.

772e66a6fc Move ALTQ from contrib to net/altq. The ALTQ code is for many years
discontinued by its initial authors. In FreeBSD the code was already
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.

48278b8846 Once pf became not covered by a single mutex, many counters in it became
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.

f870cb7f3b Use feature_present(3) to determine whether to open an INET or an
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.

3b3a8eb937 o Create directory sys/netpfil, where all packet filters should
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.
