* Refactor _PyFrame_New_NoTrack() and PyFunction_NewWithQualName() code. * PyFrame_New() checks for _PyEval_BuiltinsFromGlobals() failure. * Fix a ref leak in _PyEval_BuiltinsFromGlobals() error path. * Complete PyFunction_GetModule() documentation: it returns a borrowed reference and it can return NULL. * Move _PyEval_BuiltinsFromGlobals() definition to the internal C API. * PyFunction_NewWithQualName() uses _Py_IDENTIFIER() API for the "__name__" string to make it compatible with subinterpreters.
