[issue28870] Reduce stack consumption of PyObject_CallFunctionObjArgs() and like

[STINNER Victor]

STINNER Victor added the comment:

no_small_stack.patch: And now something completely different, a patch to remove the "small stack" alllocated on the C stack, always use the heap memory. FYI I created no_small_stack.patch from less_stack.patch.

As expected, the stack usage is lower:

* less_stack.patch: 384 bytes/call
* no_small_stack.patch: 368 bytes/call

I didn't check the performance of no_small_stack.patch yet.
