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

OK henning@, camield@
Tested by camield@ and Alexey E. Suslikov

Add new function if_link_state_change() to take care of sending messages
on the routing socket and notifying carp() of link changes.

Convert carp(4) to behave more like a regular interface, much in the same
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.

add a congestion indicator to if_queue. It is set when the input queue
is full, along with a timer that unsets it again after 10ms.
The input queue beeing full is a reliable indicator for CPU overload, and
