[RFC] ifconfig description support in rc.d

[cc'ing current_at_ as rc_at_ looks too quite]

Hi.

Since ifconfig has grown to label interfaces with
ifconfig $ifname description "foobar", what about
to give it more life and store i/face descriptions
semi-permanently, so they will survive between reboots?

This patch adds a functionality to rc.d to label
interfaces at boot time.

Comments are welcome.
