Actually, while adding a refcounted wrapper around xmlDoc, I've made more
changes/added more helpers which should make it possible to hide these
xmlNodePtr from our public API. We would expose either GVirConfigObject
or GVirConfigXmlNode as a wrapper around xmlNodePtr and provide helpers
to manipulate the xml content they wrap (stuff like new_child,
set_attributes, ...)

Ah good point, didn't think about this. Time for some noinst_HEADERS in our
Makefile.am. I also need to make sure libvirt-gconfig/libvirt-gconfig.h
doesn't reference it.
