assignments to the literal values it would have returned.
The concept of set_rcvar() was nice in theory, but the forks
it creates are a drag on the startup process, which is especially
noticeable on slower systems, such as embedded ones.
During the discussion on freebsd-rc@ a preference was expressed for
using ${name}_enable instead of the literal values. However the
code portability concept doesn't really apply since there are so
many other places where the literal name has to be searched for
and replaced. Also, using the literal value is also a tiny bit
faster than dereferencing the variables, and every little bit helps.

o Make the pfsync.ko actually usable. Before this change loading it
didn't register protosw, so was a nop. However, a module /boot/kernel
did confused users.
o Rewrite the way we are joining multicast group:
- Move multicast initialization/destruction to separate functions.
- Don't allocate memory if we aren't going to join a multicast group.
- Use modern API for joining/leaving multicast group.
- Now the utterly wrong pfsync_ifdetach() isn't needed.
o Move module initialization from SYSINIT(9) to moduledata_t method.
o Refuse to unload module, unless asked forcibly.
o Improve a bit some FreeBSD porting code:
- Use separate malloc type.
- Simplify swi sheduling.
This change is probably wrong from VIMAGE viewpoint, however pfsync
wasn't VIMAGE-correct before this change, too.

allow them to start after netif. There were too many problems reported
with this change in the short period of time that it lived in HEAD, and
we are too late in the release cycle to properly shake it out.
IMO the issue of having the firewalls up before the network is still a
valid concern, particularly for pf whose default state is wide open.
However properly solving this issue is going to take some investment
on the part of the people who actually use those tools.
This is not a strict reversion of all the changes for r193198 since it
also included some simplification of the BEFORE/REQUIRE logic which is
still valid for ipfilter and ip6fw.

already does. This eliminates a logical inconsistency, and a small
window where the system is open after the network comes up.

which can be used to turn off multicast pfsync support, and enable
the transmission of directed PFSYNC (IP protocol: 240) packets to
a specific "sync peer" host.

and takes over mountcritlocal's role as the early / late divider. This
makes it far easier to add rc scripts which need to run early, such as a
startup script for zfs, which is right around the corner.
This change should be a no-op; I have verified that the only change in
rcorder's output is the insertion of FILESYSTEMS immediately after
mountcritlocal.

system boot, and hook it up in the system.
The separate script is needed because in the presence of various
interface lists in rc.conf ($network_interfaces, $cloned_interfaces,
$sppp_interfaces, $gif_interfaces, more to come) it is hard to start
them orderly, so that pfsync is brought up after its syncdev, which
is required for the proper startup of pfsync.
