b1e4abd246 Give struct socket structures a ref counting interface similar to
vnodes.  This will hopefully serve as a base from which we can
expand the MP code.  We currently do not attempt to obtain any
mutex or SX locks, but the door is open to add them when we nail
down exactly how that part of it is going to work.

99efe4f0f8 Remove ifnet.if_mpsafe for now. If this is needed, it won't be needed
until much later when the network stack locking is farther along.

Seems to be a typo for typedef, but we don't want this non-style(9)

8071913df2 Pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2.
Have sys/net/route.c:rtrequest1(), which takes ``rt_addrinfo *''
as the argument.  Pass rt_addrinfo all the way down to rtrequest1
and ifa->ifa_rtrequest.  3rd argument of ifa->ifa_rtrequest is now
``rt_addrinfo *'' instead of ``sockaddr *'' (almost noone is
using it anyways).

Benefit: the following command now works.  Previously we needed
two route(8) invocations, "add" then "change".
# route add -inet6 default ::1 -ifp gif0

Remove unsafe typecast in rtrequest(), from ``rtentry *'' to
``sockaddr *''.  It was introduced by 4.3BSD-Reno and never
corrected.

This fixes the panic when receiving a packet with an unknown tag, and

830cc17841 Two main changes here:
+ implement "limit" rules, which permit to limit the number of sessions
   between certain host pairs (according to masks). These are a special
   type of stateful rules, which might be of interest in some cases.
   See the ipfw manpage for details.

 + merge the list pointers and ipfw rule descriptors in the kernel, so
   the code is smaller, faster and more readable. This patch basically
   consists in replacing "foo->rule->bar" with "rule->bar" all over
   the place.
   I have been willing to do this for ages!

Yes this really is rather silly and the implementation is overkill given
that you are only allowed one of them, but NetBSD implements cloning on
this device and it's a less cluttered example of cloning then most.
