[libvirt] [libvirt-designer PATCHv2 0/9] Handle more devices in GVirDesignerDomain

This goes on top of v2 of the "Improve disk bus type generation" series. Diff with the previous version is that it's rebased against latest master, and I've reworked "Implement gvir_designer_domain_add_sound()" patch to address danpb's comments (gvir_designer_domain_add_sound() is now a public method that must be called explicitly rather than being implicitly called on domain creation.
