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.

jumbo MTUs, so either let the driver set it's own value or use 9000
byte jumbo frames by default.

useless layers of indirection and make the code way cleaner overall.
this is just the start, more to come...
worked very hard on by Ryan and me in Montreal last week, on the airplane to
vancouver and yesterday here in calgary. it hurt.

This converts if_link_state_change() to a generic usable
callback with dohooks().

style as vlan(4). carp interfaces no longer require the physical interface
to be on the same subnet as the carp interface, or even that the physical
interface has an adress at all, so CARP can now be used on /30 networks.

there is now a TAILQ with all interface groups as members, and
in struct ofnet there is only a pointer to the group structure stored
and not its name.

Every interface has its if-family as default group.

The input queue beeing full is a reliable indicator for CPU overload, and
this flag allows other subsystems to cope with the situation.
