qom: Add helper function for getting user objects root
Add object_get_objects_root() function which is a convenience for obtaining the Object * located at /objects in the object composition tree. Convert existing code over to use the new API where appropriate. Signed-off-by: Daniel P. Berrange <berrange@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
