* consolidate the topical structs under a single top-level _PyRuntimeState struct
* add a check-c-globals.py script that helps identify runtime globals

Other globals are excluded (see globals.txt and check-c-globals.py).

"XXX() takes Y argument (Z given)") before
the function '_PyArg_NoStackKeywords()' was called.

error : "XXX() takes no keyword arguments".

INADA Naoki aa289a59ff bpo-29548: Recommend PyObject_Call APIs over PyEval_Call APIs. (GH-75)
PyEval_Call* APIs are not documented and they doesn't respect PY_SSIZE_T_CLEAN.
So add comment block which recommends PyObject_Call* APIs to ceval.h.

This commit also changes PyEval_CallMethod and PyEval_CallFunction
implementation same to PyObject_CallMethod and PyObject_CallFunction
to reduce future maintenance cost.  Optimization to avoid temporary
tuple are copied too.

PyEval_CallFunction(callable, "i", (int)i) now calls callable(i) instead of
raising TypeError.  But accepting this edge case is backward compatible.

Victor Stinner 516b98161a Optimize slots: avoid temporary PyMethodObject
Issue #29507: Optimize slots calling Python methods. For Python methods, get
the unbound Python function and prepend arguments with self, rather than
calling the descriptor which creates a temporary PyMethodObject.

Add a new _PyObject_FastCall_Prepend() function used to call the unbound Python
method with self. It avoids the creation of a temporary tuple to pass
positional arguments.

Avoiding temporary PyMethodObject and avoiding temporary tuple makes Python
slots up to 1.46x faster. Microbenchmark on a __getitem__() method implemented
in Python:

Median +- std dev: 121 ns +- 5 ns -> 82.8 ns +- 1.0 ns: 1.46x faster (-31%)

Raymond Hettinger 5cd87a8d61 Reduce load factor (from 66% to 60%) to improve effectiveness of linear probing.
Decreased density gives better collision statistics (average of 2.5 probes in a
full table versus 3.0 previously) and fewer occurences of starting a second
possibly overlapping sequence of 10 linear probes.  Makes resizes a little more
frequent but each with less work (fewer insertions and fewer collisions).

INADA Naoki 35a96a25ee Issue #29383: reduce temporary interned unicode
add_methods(), add_members(), and add_getset() used PyDict_SetItemString()

So descr_new() and PyDict_SetItemString() creates interned unicode from same
C string.

This patch takes interned unicode from descriptor, and use PyDict_SetItem()
instead of PyDict_SetItemString().

Only a few functions call call_method() and call it with a fixed number of

function, replace it with an array allocated on the stack with the exact number
of argumlents.

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

test_python_getitem: 1344 => 1008 (-336 B)
test_python_iterator: 1568 => 1232 (-336 B)

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.

Victor Stinner d1e35dd9ee Fix _PyObject_CallFunctionVa(), use the small stack
Issue #28915. Oops, I disabled the small stack to test both code paths. It's
now fixed.

Victor Stinner 0ca246c5e7 Inline PyEval_EvalFrameEx() in callers
The PEP 523 modified PyEval_EvalFrameEx(): it's now an indirection to
interp->eval_frame().

Inline the call in performance critical code. Leave PyEval_EvalFrame()
unchanged, this function is only kept for backward compatibility.
