Move these private functions to the internal C API (pycore_abstract.h): * _Py_convert_optional_to_ssize_t() * _PyNumber_Index() Argument Clinic now emits #include "pycore_abstract.h" when these functions are used. The parser of the c-analyzer tool now uses a list of files which use the limited C API, rather than a list of files using the internal C API.
