The PyStdPrinter_Type type now uses the Py_TPFLAGS_DISALLOW_INSTANTIATION flag to disallow instantiation, rather than seting a tp_init method which always fail. Write also unit tests for PyStdPrinter_Type.

The funny part is that technically, Py_TPFLAGS_DISALLOW_INSTANTIATION or setting tp_new explicitly to NULL are not needed. Since it's a static type, tp_new is NULL and tp_base is NULL, it gets Py_TPFLAGS_DISALLOW_INSTANTIATION flag automatically. |
