"[Python] #2907 Fix returning null from functions with output
parameters.  Ensures OUTPUT and INOUT typemaps are handled
consistently wrt return type.

New declaration of SWIG_Python_AppendOutput is now:

  SWIG_Python_AppendOutput(PyObject* result, PyObject* obj, int is_void);

The 3rd parameter is new and the new $isvoid special variable
should be passed to it, indicating whether or not the wrapped
function returns void.

Also consider replacing with:

  SWIG_AppendOutput(PyObject* result, PyObject* obj);

which calls SWIG_Python_AppendOutput with same parameters but adding $isvoid
for final parameter."
