Add a simple dhcp client for rump kernels. It uses code from dhcpcd
for talking to the server and for setting the interface address
and route. However, otherwise it is quite different, since we need
to be working under the assumptions that there is no stable storage
on a rump instance, and that there are n networking stacks on a
given host.

Don't use const foo const as type, one const is enough.

fix some error handling.

Use __dead

Record address from offer to actually send it as part of the
request. May fix interaction with some pickier dhcp servers
(like riz's). Thanks to Jeff for debugging assistance.
