Support help() using the Signature Module

The signature module will be used to generate automated
documentation by using the function signatures as docstrings.

This functionality should be low-hanging fruit. Actually, it was a
bit tricky to get this working. The crucial point was to use
PyType_Modified().

The function works fine on methods.
Supporting types needs some more effort.
It is not clear why the __signature__ attribute can be added,
but the change to __doc__ is not recognized. May be related to
the absence of Py_TPFLAGS_HAVE_VERSION_TAG ?
This will be addressed another time.
