As a first user, move the global carp(4) demotion counter
into the interface group. Thus we have the possibility
to define which carp interfaces are demoted together.
Put the demotion counter into the reserved field of the carp header.
With this, we can have carp act smarter if multiple errors occur.
It now always takes over other carp peers, that are advertising
with a higher demote count. As a side effect, we can also have
group failovers without the need of running in preempt mode.
The protocol change does not break compability with older
implementations.

directly. rather provide a rt_lookup function for regular lookups,
and a rt_gettable for those that need access to the head for some reason.
the latter cases should be revisted later probably so that nothing outside
the routing core code accesses the heads at all...

to the driver that there is a listener. Somehow I assumed that it was
a handle, and was trying to figure out why it was becoming zero.

router so back out the routing stuff to pre-eurobsdcon where my machine
doesn't crash immediately.
i am happy to test diffs and report success/failures but i am not happy
to have instantaneous crashes when i reboot with a new kernel that was
compiled from pristine sources.
if you are going to be an elitist asshole then you could at least make
sure your code works.

but go through a provided wrapper.
also provide rt_lookup() instead of doing the lookup manually in many places.

when the interface is deleted to a function in route.c, and replace
the copies of that code by calls to that function
from basel almost-hackathon

to trigger an if_group_egress_build() call, stop looking at the mask in the
v4 case, at least until I figured out why we sometimes see masks full of
crap.

handles IPv4 and IPv6 as well as multipath routes.
follows default route changes, of course.
eases writing pf rulesets especially on laptops etc. that use different
interfaces depending on the environment (wired, wireless, ...)

This converts if_link_state_change() to a generic usable

The code is adopted from the FreeBSD netgraph-based Bluetooth
implementation by Maksim Yevmenkin <m_evmenkin@yahoo.com> but
all netgraph glue was replaced with usual BSD network stack
hooks. This is a work in progress. Only HCI layer works for now,
L2CAP and RFCOMM are on the way.
Help in testing from many, ok markus@.

list than physical interfaces. This makes ifa_ifwith* prefer a physical
interface over a CARP one.
This addresses the problem where a CARP interface in BACKUP state is
selected after a route change, resulting in a loss of communications
despite there being another interface available which is perfectly usable.
