Kernel: Add a LoopbackAdapter for talking to yourself via 127.0.0.1.

Browse source 
Choosing adapter for transmit is done by adapter_for_route_to(IPv4Address).
This is just hard-coded logic right now but can be expanded to support a
proper routing table.

Also start moving kernel networking code into Kernel/Net/.
