From: "Daniel P. Berrange" <berrange at redhat.com>
Move virNetDevGetIndex & virNetDevGetVLanID to virnetdev.c to
suit their functional purpose
* util/interface.c, util/interface.h: Remove virNetDevGetIndex &
virNetDevGetVLanID
* util/virnetdev.c, util/virnetdev.h: Add virNetDevGetIndex &
virNetDevGetVLanID
