qed.c: replace QEMUOptionParameter with QemuOpts
One extra change is to define QED_DEFAULT_CLUSTER_SIZE = 65536 instead
of 64 * 1024; because:
according to existing create_options, "cluster size" has default value =
QED_DEFAULT_CLUSTER_SIZE, after switching to create_opts, this has to be
stringized and set to .def_value_str. That is,
.def_value_str = stringify(QED_DEFAULT_CLUSTER_SIZE),
so the QED_DEFAULT_CLUSTER_SIZE could not be a expression.
