Serhiy Storchaka bc3fa17c30 gh-82312: Further improvement of error messages for generating AST nodes (GH-150912) 
This is a follow up of GH-17715.

* Use %T instead of _PyType_Name().
* Add the wrong type name we got for identifier and string.

Karolina SurmaandVictor Stinner 1887a95f51 gh-128341: Use _Py_ABI_SLOT in stdlib modules (#145770) 
Rename from _Py_INTERNAL_ABI_SLOT to _Py_ABI_SLOT
and define the macro using _PyABIInfo_DEFAULT.

Use the ABI slot in stdlib extension modules to enable running
a check of ABI version compatibility.

_tkinter, _tracemalloc and readline don't use the slots, hence they need
explicit handling.

 		30840706b0 gh-131421: fix ASDL grammar for Dict to have an expr?* keys field (#131419) 
In the `ast` documentation for Python:

* https://docs.python.org/3/library/ast.html#ast.Dict
it is made clear that:

> When doing dictionary unpacking using dictionary literals the expression to be expanded goes in the values list, with a `None` at the corresponding position in `keys`.

Hence, `keys` is really a `expr?*` and *not* a `expr*`.

sobolevn b2eaa75b17 gh-126105: Fix crash in ast module, when ._fields is deleted (#126115) 
Previously, if the `ast.AST._fields` attribute was deleted, attempts to create a new `as`t node would crash due to the assumption that `_fields` always had a non-NULL value. Now it has been fixed by adding an extra check to ensure that `_fields` does not have a NULL value (this can happen when you manually remove `_fields` attribute).

Jelle Zijlstra e0422198fb gh-117486: Improve behavior for user-defined AST subclasses (#118212) 
Now, such classes will no longer require changes in Python 3.13 in the normal case.
The test suite for robotframework passes with no DeprecationWarnings under this PR.

I also added a new DeprecationWarning for the case where `_field_types` exists
but is incomplete, since that seems likely to indicate a user mistake.

Brett Simmers c2627d6eea gh-116322: Add Py_mod_gil module slot (#116882) 
This PR adds the ability to enable the GIL if it was disabled at
interpreter startup, and modifies the multi-phase module initialization
path to enable the GIL when loading a module, unless that module's spec
includes a slot indicating it can run safely without the GIL.

PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went
with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148.

A warning will be issued up to once per interpreter for the first
GIL-using module that is loaded. If `-v` is given, a shorter message
will be printed to stderr every time a GIL-using module is loaded
(including the first one that issues a warning).
