for the time being we focus on the ovs-related commands.

Our initial prototype overloaded PF_ROUTE: if the first
message on a socket carried a PF_NETLINK identifier then
all subsequent i/o is routed to the netlink routines.
However this required small changes to route.c so now
we are going to do the real thing (using a PF_NETLINK domain).
