Make the MI LANCE driver standalone, and use cfattach to resolve

naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.

Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit.  Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.
