[libvirt] [libvirt-glib] Add API to redefine an existing domain

[Christophe Fergeau]

Hey,

Reading this patch, I'm wondering if gvir_domain_set_config might achieve
what you are after (it's not implemented either)

For the record, I'm not sure I like the naming here.

This is unused

Shouldn't handle be assigned to some persistent state? My guess is
domain->priv->handle.
