Recognize when we are sending to a unicast destination IP address and

instead of using BPF, which currently will always set the destination
MAC to broadcast, send using a SOCK_RAW socket and sendmsg() so the
frame has a unicast destination MAC.

Fixes an issue when using a bootp forwarder where unicast DHCPREQUESTs
are dropped at the router/gateway until we reach T2/REBINDING and
change the destination IP to broadcast.

ok henning@ (but doesn't like using a raw socket for this)
