The function is like Py_AtExit() but for a single interpreter. This is a companion to the atexit module's register() function, taking a C callback instead of a Python one.
We also update the _xxinterpchannels module to use _Py_AtExit(), which is the motivating case. (This is inspired by pain points felt while working on gh-101660.)
Several platforms don't define the static_assert macro despite having
compiler support for the _Static_assert keyword. The macro needs to be
defined since it is used unconditionally in the Python code. So it
should always be safe to define it if undefined and not in C++11 (or
later) mode.
Hence, remove the checks for particular platforms or libc versions,
and just define static_assert anytime it needs to be defined but isn't.
That way, all platforms that need the fix will get it, regardless of
whether someone specifically thought of them.
Also document that certain macOS versions are among the platforms that
need this.
The C2x draft (currently expected to become C23) makes static_assert
a keyword to match C++. So only define the macro for up to C17.

* bpo-22708: Upgrade HTTP CONNECT to protocol HTTP/1.1 (GH-NNNN)
Use protocol HTTP/1.1 when sending HTTP CONNECT tunnelling requests;
generate Host: headers if one is not already provided (required by
HTTP/1.1), convert IDN domains to punycode in HTTP CONNECT requests.
* Refactor tests to pass under -bb (fix ByteWarnings); missed some lines >80.
* Use consistent 'tunnelling' spelling in Lib/http/client.py
* Lib/test/test_httplib: Remove remnant of obsoleted test.
* Use dict.copy() not copy.copy()
* fix version changed
* Update Lib/http/client.py

In gh-102744 we added is_core_module() (in Python/import.c), which relies on get_core_module_dict() (also added in that PR). The problem is that_PyImport_FixupBuiltin(), which ultimately calls is_core_module(), is called on the builtins module before interp->builtins_copyis set. Consequently, the builtins module isn't considered a "core" module while it is getting "fixed up" and its module def m_copy erroneously gets set. Under isolated interpreters this causes problems since sys and builtins are allowed even though they are still single-phase init modules. (This was discovered while working on gh-101660.)
The solution is to stop relying on get_core_module_dict() in is_core_module().
Fix a (correct) warning about potential uses of uninitialized memory in
_xxsubinterpreter. Unlike newly allocated PyObject structs or global
structs, stack-allocated structs are not initialised, and a few places in
the code expect the _sharedexception struct data to be either NULL or
initialised.
Prior to https://github.com/python/cpython/pull/25300, the
make_ssl_data.py script used various tables, exposed in _ssl, to update
the error list.
After that PR, this is no longer used. Moreover, the err_names_to_codes
map isn't used at all. Clean those up. This gets them out of the way if,
in the future, OpenSSL provides an API to do what the code here is doing
directly. (https://github.com/openssl/openssl/issues/19848)
Fix an issue where `__new__()` and `__init__()` were not called on subclasses of `pathlib.PurePath` and `Path` in some circumstances.
Paths are now normalized on-demand. This speeds up path construction, `p.joinpath(q)`, and `p / q`.
