[omniORB] patch for python unmarshalling of union

[Ted Horst]

Hi all,

I just started using omniORB through the python bindings, and I ran into a  
bug unmarshalling unions.  The spec says:

* If the discriminant is not listed, and there is no default, the value is None.

But the unmarshalling code did not handle this case.  The following patch  
fixes the problem:

          assert(PyTuple_Check(t_o));
          value = unmarshalPyObject(stream, PyTuple_GET_ITEM(t_o, 2));
        }
+       else {
+         value = Py_None;
+         Py_INCREF(value);
+       }
        }

        PyObject* untuple = PyTuple_New(2);

          assert(PyTuple_Check(t_o));
          value = unmarshalPyObject(stream, PyTuple_GET_ITEM(t_o, 2));
+       }
+       else {
+         value = Py_None;
+         Py_INCREF(value);
        }
        }
