qobject: Change qobject_to_json()'s value to GString
qobject_to_json() and qobject_to_json_pretty() build a GString, then covert it to QString. Just one of the callers actually needs a QString: qemu_rbd_parse_filename(). A few others need a string they can modify: qmp_send_response(), qga's send_response(), to_json_str(), and qmp_fd_vsend_fds(). The remainder just need a string. Change qobject_to_json() and qobject_to_json_pretty() to return the GString. qemu_rbd_parse_filename() now has to convert to QString. All others save a QString temporary. to_json_str() actually becomes a bit simpler, because GString provides more convenient modification functions.
