Seven macro incompatibilities with the Limited API were fixed, and the

macros PyIter_Check, PyIndex_Check and PyExceptionClass_Name were added as

functions. The return type of PyExceptionClass_Name is "const char \*".

macros :c:func:`PyIter_Check`, :c:func:`PyIndex_Check` and

:c:func:`PyExceptionClass_Name` were added as functions.

A script for automatic macro checks was added.
