Use directly the PyThreadState_Get() function in public header files,
since PyThreadState_GET() macro is just an alias to it in pratice in
these files.
* bpo-42979: Enhance abstract.c assertions checking slot result
Add _Py_CheckSlotResult() function which fails with a fatal error if
a slot function succeeded with an exception set or failed with no
exception set: write the slot name, the type name and the current
exception (if an exception is set).
Previously, the result could have been an instance of a subclass of int.
Also revert bpo-26202 and make attributes start, stop and step of the range
object having exact type int.
Add private function _PyNumber_Index() which preserves the old behavior
of PyNumber_Index() for performance to use it in the conversion functions
like PyLong_AsLong().
Always declare PyIndex_Check() as an opaque function to hide
implementation details: remove PyIndex_Check() macro. The macro
accessed directly the PyTypeObject.tp_as_number member.
Some inline functions use mixed declarations and code. These end up
visible in third-party code that includes Python.h, which might not be
using a C99 compiler. Fix by moving the declarations first, like in
the old days.
* sys.settrace(), sys.setprofile() and _lsprof.Profiler.enable() now
properly report PySys_Audit() error if "sys.setprofile" or
"sys.settrace" audit event is denied.
* Add _PyEval_SetProfile() and _PyEval_SetTrace() function: similar
to PyEval_SetProfile() and PyEval_SetTrace() but take a tstate
parameter and return -1 on error.
* Add _PyObject_FastCallTstate() function.

git grep -lwz $old | xargs -0 sed -i "s/\b$old\b/$new/g"
and then cleaned up:
- Revert changes to in docs & news
- Revert changes to backcompat defines in headers
- Nudge misaligned comments
* Add backcompat defines and move non-limited API declaration to cpython/
This partially reverts commit 2ff58a24e8
which added PyObject_CallNoArgs to the 3.9+ stable ABI. This should not
be done; there are enough other call APIs in the stable ABI to choose from.
* Adjust documentation
Mark all newly public functions as added in 3.9.
Add a note about the 3.8 provisional names.
Add notes on public API.
* Put PyObject_CallNoArgs back in the limited API
* Rename PyObject_FastCallDict to PyObject_VectorcallDict
* Add _PyObject_VectorcallTstate() function: similar to
_PyObject_Vectorcall(), but with tstate parameter
* Add tstate parameter to _PyObject_MakeTpCall()
There are plenty of legitimate scripts in the tree that begin with a
`#!`, but also a few that seem to be marked executable by mistake.
Found them with this command -- it gets executable files known to Git,
filters to the ones that don't start with a `#!`, and then unmarks
them as executable:
$ git ls-files --stage \
| perl -lane 'print $F[3] if (!/^100644/)' \
| while read f; do
head -c2 "$f" | grep -qxF '#!' \
|| chmod a-x "$f"; \
done
Looking at the list by hand confirms that we didn't sweep up any
files that should have the executable bit after all. In particular
* The `.psd` files are images from Photoshop.
* The `.bat` files sure look like things that can be run.
But we have lots of other `.bat` files, and they don't have
this bit set, so it must not be needed for them.

The fact that keyword names are strings is now part of the vectorcall and `METH_FASTCALL` protocols. The biggest concrete change is that `_PyStack_UnpackDict` now checks that and raises `TypeError` if not.

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.
