Note that this commit doesn't actually do interface renaming.  It just
paves the way by a) breaking the use of if_name and if_unit as both the
interface name and driver name/unit and b) insuring the interface name
is stored in storage we can modify rather then driver dependent, usually
static storage.

It also ends the tyranny of <drivername><unitnumber> naming which didn't
make sense in many cases.  For instance, some interface types like stf
can only have one interface to calling it stf0 instead of stf or 6to4
is stupid.  Another evil example is how the ef(4) driver uses the unit
number to store the Ethernet frame type of the interface.

I defiantly recommend taking this route, but I'm a little biased. :-)
