Add IP load balancing support for carp(4).

This provides a similar functionality as ARP balancing,
but also works for traffic that comes across routers.
IPv6 is supported as well.
The configuration scheme will change as soon we have sth better.

Also add support for changing the MAC address on carp(4)
interfaces. (code from mcbride)

Tested by pyr@ and reyk@
