Replace the if_name and if_unit members of struct ifnet with new members

if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

Reviewed By:	njl, imp
Tested On:	i386, amd64, sparc64
Obtained From:	NetBSD (if_xname)
