Added exception to the rule that the buffer returned by PyString_AsString()
and PyString_AsStringAndSize() for strings that were just created using
PyString_FromStringAndSize(NULL, n).

This closes bug #117377.

Added warning about passing NULL to the concrete object functions; many of
them use the appropriate Py<Type>_Check() test, but do not check for NULL.
