1741441649 Issue #29029: Speed up processing positional arguments in 
PyArg_ParseTupleAndKeywords(), _PyArg_ParseTupleAndKeywordsFast() and like.

0c4a828cad Run Argument Clinic: METH_VARARGS=>METH_FASTCALL 
Issue #29286. Run Argument Clinic to get the new faster METH_FASTCALL calling
convention for functions using "boring" positional arguments.

Manually fix _elementtree: _elementtree_XMLParser_doctype() must remain
consistent with the clinic code.

29d39cc8f5 Add _PyArg_NoStackKeywords() helper function 
Issue #29286. Similar to _PyArg_NoKeywords(), but expects a tuple of keyword
names, instead of a dict.

6518a93cb1 Add _PyArg_ParseStack() helper function 
Issue #29286. Function similar to PyArg_ParseTuple(), but uses a C array of
PyObject* to pass arguments. Don't support the compatibility mode.

415c5107be Inline call_function() 
Issue #29227: Inline call_function() into _PyEval_EvalFrameDefault() using
Py_LOCAL_INLINE to reduce the stack consumption.

It reduces the stack consumption, bytes per call, before => after:

test_python_call: 1152 => 1040 (-112 B)
test_python_getitem: 1008 => 976 (-32 B)
test_python_iterator: 1232 => 1120 (-112 B)

=> total: 3392 => 3136 (- 256 B)

2f7964393d Issue #29157: getrandom() is now preferred over getentropy() 
The glibc now implements getentropy() on Linux using the getrandom() syscall.
But getentropy() doesn't support non-blocking mode.

Since getrandom() is tried first, it's not more needed to explicitly exclude
getentropy() on Solaris. Replace:

    if defined(HAVE_GETENTROPY) && !defined(sun)

with

    if defined(HAVE_GETENTROPY)

Enhance also dev_urandom() and pyurandom() documentation.

from /dev/urandom.

bc08ab4598 Add _PY_FASTCALL_SMALL_STACK constant 
Issue #28870: Add a new _PY_FASTCALL_SMALL_STACK constant, size of "small
stacks" allocated on the C stack to pass positional arguments to
_PyObject_FastCall().

_PyObject_Call_Prepend() now uses a small stack of 5 arguments (40 bytes)
instead of 8 (64 bytes), since it is modified to use _PY_FASTCALL_SMALL_STACK.

the last mile, Serhiy Storchaka for reviewing the code, and to
Victor Stinner for suggesting the idea (originally implemented
in the PyPy project).
