bpo-37194: Add a new public PyObject_CallNoArgs() function (GH-13890)
Add a new public PyObject_CallNoArgs() function to the C API: call a callable Python object without any arguments. It is the most efficient way to call a callback without any argument. On x86-64, for example, PyObject_CallFunctionObjArgs(func, NULL) allocates 960 bytes on the stack per call, whereas PyObject_CallNoArgs(func) only allocates 624 bytes per call. It is excluded from stable ABI 3.8. Replace private _PyObject_CallNoArg() with public PyObject_CallNoArgs() in C extensions: _asyncio, _datetime, _elementtree, _pickle, _tkinter and readline.
