Introduce a new API to get libvirt version. It is worth noting, that libvirt-admin and libvirt share the same version number. Unfortunately, our existing API isn't generic enough to be used with virAdmConnectPtr as well. Also this patch wires up this API to the virt-admin client as a generic cmdVersion command.
