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.

+        The API and ABI of struct ifnet have been changed by removing
+        the if_name and if_unit members and replacing them with
+        if_xname, if_dname, and if_dunit.  All network drivers and most
+        userland programs which include net/if_var.h must be updated
+        and recompiled.  __FreeBSD_version has been bumped to 501113 to
+        reflect this change.
