interface renaming

[Richard Coleman]

There was a big commit to FreeBSD-current to do interface renaming to 
bring it in line with other *BSD.  Below is the commit message.  Is this 
change of interest for DFBSD?  If so, I could start work on it.

  Log:
  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.
