I think this request is mainly for other managment apps' use, for
virsh, it's not that deserved, "virsh destroy dom && virsh edit dom"
can do the work.

Currently, the program needs to do the following to rename, e.g:

virDomainDestroyFlags
virDomainGetXMLDesc
--change XML
virDomainUndefineFlags
virDomainDefineFlags

Having a renaming API will ease the use, but as I said, I'm not sure
if it's deserved from different p.o.v, because it may only makes sense
for inactive objects.
