Before exiting, you need a message. If there is also an exception, you
may want to display it. If there is no exception, you may want to
display the Python traceback. All these tasks are already implemented
in Py_FatalError.

If the defaullt behaviour of Py_FatalError() cannot be modified, a new
function should be be added, a function sharing its code with
Py_FatalError().

Example: a new private function "void initerror(const char *message)"
only used during Py_Initialize().
