[libvirt] [libvirt-glib 06/13] Use gvir_config_object_attach where appropriate

[Christophe Fergeau]

This allows us to properly refcount the underlying xmlDocPtr (and
the associated xmlNodes) to avoid trying to free twice the same
xmlNodes when disposing of GVirConfigObject referencing the same
nodes.
