Message:

networking improvements

• start the networking stack from init
• add loopback network interface driver (cherrypicked and sanitized from lp:~helenos-nicf/helenos/nicf)
• add libnic and various small pieces from lp:~helenos-nicf/helenos/nicf
• fix client side of NIC_GET_ADDRESS
• net binary overhaul

Note: "ping 127.0.0.1" works, but the first three pings timeout for some reason
