bpo-35134: Add Include/cpython/fileutils.h header file (GH-18493)
Move CPython C API from Include/fileutils.h into a new Include/cpython/fileutils.h header file which is included by Include/fileutils.h. Exclude the following private symbols from the limited C API: * _Py_error_handler * _Py_GetErrorHandler() * _Py_DecodeLocaleEx() * _Py_EncodeLocaleEx()
