This is mostly a refactor to clean things up a bit, most notably the "XI namespace" code.
Making the session opaque requires adding the following internal-only functions:
* _PyXI_NewSession()
* _PyXI_FreeSession()
* _PyXI_GetMainNamespace()

gh-133740: Fix locale.nl_langinfo(ALT_DIGITS) (GH-134468)
Set the LC_CTYPE locale to the LC_TIME locale even if
nl_langinfo(ALT_DIGITS) result is ASCII. The result is a list
separated by NUL characters and the code only checks the first list
item which can be ASCII whereas following items are non-ASCII.
Fix test__locale for the uk_UA locale on RHEL 7.

The `__main__` module imported in the `_pyrepl` module points to the `_pyrepl` module itself when the interpreter was launched without `-m` option and didn't execute a module,
while it's an unexpected behavior that `__main__` can be `_pyrepl` and relative imports such as `from . import *` works based on the `_pyrepl` module.

Refactor shared code in train_dict and finalize_dict
(cherry picked from commit c64a21454b)
Co-authored-by: Emma Smith <emma@emmatyping.dev>
It now supports a "full" fallback to _PyFunction_GetXIData() and then `_PyPickle_GetXIData()`.
There's also room for other fallback modes if that later makes sense.

gh-134209: use heap-allocated memory in `_curses.window.{instr,getstr}` (GH-134283)
* made curses buffer heap allocated instead of stack
* change docs to explicitly mention the max buffer size
* changing GetStr() function to behave similarly too
* Update Doc/library/curses.rst
* Update instr with proper return error handling
* Update Modules/_cursesmodule.c
* change to strlen and better memory safety
* change from const int to Py_ssize_t
* add mem allocation guard
* update versionchanged to mention it was an increase.
* explicitly use versionchanged 3.14 as that is its own branch now.
TESTED: `python -m test -u curses test_curses`

(cherry picked from commit 2d82ab761a)
Co-authored-by: Kumar Aditya <kumaraditya@python.org>
This converts functions, code, str, bytes, bytearray, and memoryview objects to PyCodeObject,
and ensure that the object looks like a script. That means no args, no return, and no closure.
_PyCode_GetPureScriptXIData() takes it a step further and ensures there are no globals.
We also add _PyObject_SupportedAsScript() to the internal C-API.

This reverts commit 3c73cf5 (gh-133497), which itself reverted
the original commit d270bb5 (gh-133221).
We reverted the original change due to failing android tests.
The checks in _PyCode_CheckNoInternalState() were too strict,
so we've relaxed them.

"Stateless" code is a function or code object which does not rely on external state or internal state.
It may rely on arguments and builtins, but not globals or a closure. I've left a comment in
pycore_code.h that provides more detail.
We also add _PyFunction_VerifyStateless(). The new functions will be used in several later changes
that facilitate "sharing" functions and code objects between interpreters.
This reverts commit 811edcf (gh-133232), which itself reverted the original commit 811edcf (gh-133128).
We reverted the original change due to failing s390 builds (a big-endian architecture).
It ended up that I had not accommodated op caches.
