[libvirt] [PATCH 04/16] Rename low level macvlan creation APIs

From: "Daniel P. Berrange" <berrange at redhat.com>
Rename ifaceMacvtapLinkAdd to virNetDevMacVLanCreate and
ifaceLinkDel to virNetDevMacVLanDelete. Strictly speaking
the latter isn't restricted to macvlan devices, but that's
the only use libvirt has for it.
* util/interface.c, util/interface.h,
util/virnetdevmacvlan.c: Rename APIs
