Some items remained uninitialized if _sre.template() was called with invalid
indices. Then attempt to clear them in the destructor led to dereferencing
of uninitialized pointer.

[3.12] gh-106033: Get rid of new occurrences of PyDict_GetItem and PyObject_HasAttr (GH-106034)
These functions are broken by design because they discard any exceptions raised
inside, including MemoryError and KeyboardInterrupt. They should not be
used in new code.

For a while now, pending calls only run in the main thread (in the main interpreter). This PR changes things to allow any thread run a pending call, unless the pending call was explicitly added for the main thread to run.

We are changing it to be more flexible that a strict bool can be for possible future expanded used cases.

in the following functions, check if interpreter is finalizing and raise `RuntimeError` with appropriate message:
* `_thread.start_new_thread` and thus `threading`

When I added the relevant condition to type_ready_set_bases() in gh-103912, I had missed that the function also sets tp_base and ob_type (if necessary). That led to problems for third-party static types.
We fix that here, by making those extra operations distinct and by adjusting the condition to be more specific.
(cherry picked from commit 1469393)
Co-authored-by: Eric Snow ericsnowcurrently@gmail.com
In gh-103912 we added tp_bases and tp_mro to each PyInterpreterState.types.builtins entry. However, doing so ignored the fact that both PyTypeObject fields are public API, and not documented as internal (as opposed to tp_subclasses). We address that here by reverting back to shared objects, making them immortal in the process.

gh-103142: Upgrade binary builds and CI to OpenSSL 1.1.1u (GH-105174)
Upgrade builds to OpenSSL 1.1.1u.
This OpenSSL version addresses a pile if less-urgent CVEs since 1.1.1t.
The Mac/BuildScript/build-installer.py was already updated.
Also updates _ssl_data_111.h from OpenSSL 1.1.1u, _ssl_data_300.h from 3.0.9, and adds a new _ssl_data_31.h file from 3.1.1 along with the ssl.c code to use it.
Manual edits to the _ssl_data_300.h file prevent it from removing any existing definitions in case those exist in some peoples builds and were important (avoiding regressions during backporting).
backports of this prior to 3.12 will not include the openssl 3.1 header.

Quoting autoconf (v2.71):

Not all systems provide sys/time.h, but those that do, all allow
you to include it and time.h simultaneously.

gh-104372: Drop the GIL around the vfork() call. (GH-104782)
On Linux where the `subprocess` module can use the `vfork` syscall for
faster spawning, prevent the parent process from blocking other threads
by dropping the GIL while it waits for the vfork'ed child process `exec`
outcome. This prevents spawning a binary from a slow filesystem from
blocking the rest of the application.
Fixes GH-104372.
