Move device nodes into a /dev/net/ directory, to avoid conflict with
existing devices (e.g.: tunX). This may need a little more thought.

Create a /dev/netX alias for devices. net0 is reserved.

Allow wiring of net aliases in /boot/device.hints of the form:
hint.net.1.dev="lo0"
hint.net.12.ether="00:a0:c9:c9:9d:63"
