We tried this before with a dict and for all interned strings. That ran into problems due to interpreter isolation. However, exclusively using a per-interpreter cache caused some inconsistency that can eliminate the benefit of interning. Here we circle back to using a global cache, but only for statically allocated strings. We also use a more-basic _Py_hashtable_t for that global cache instead of a dict.
Ideally we would only have the global cache, but the optional isolation of each interpreter's allocator means that a non-static string object must not outlive its interpreter. Thus we would have to store a copy of each such interned string in the global cache, tied to the main interpreter.

Correct documentation for AF_PACKET (GH-112339)
Protocol in the address tuple should *not* be in the network-byte-order, because it is converted internally[1].
[1] 89ddea4886/Modules/socketmodule.cGH-L2144
network byte order doesn't make sense for a python level int anyways. It's a fixed size C serialization concept.

Revert "[3.12] gh-105699: Re-enable the Multiple-Interpreters Stress Tests (gh-107572) (#107783)"
This reverts commit a4aac7d3ea.
The stress tests are still failing on FreeBSD.
This change makes sure sys.path[0] is set properly for subinterpreters. Before, it wasn't getting set at all.
This change does not address the broader concerns from gh-109853.
(cherry-picked from commit a040a32ea2)
We had disabled them due to crashes they exposed, which have since been fixed.

The "Check if generated files are up to date" job of GitHub Actions

(https://github.com/tiran/cpython_autoconf) is no longer used.
