This was added in the add of `_io`, isn't used since bpo-21859 when a
`_pyio` implementation was added which defines `FileIO` lower down in
the file.

Update `test_io` `_check_warn_on_dealloc` to use `self.` to dispatch to
different I/O implementations.
Update the `_pyio` implementation to match expected behavior, using the
same `_dealloc_warn` design as the C implementation uses to report the
topmost `__del__` object.
The FileIO one now matches all the others, so can use IOBase. There was
a missing check on closing (self._fd must be valid), add that check

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.

Two special methods, __buffer__ and __release_buffer__ were added to
Python 3.12 by PEP 688. The C API Type Object documentation for slots
includes `tp_as_buffer`, and sub-slots `bf_getbuffer`, `bf_releasebuffer`
but does not refer to the Python Data Model version of those. Add the
missing references.

gh-72680: Fix false positives when using zipfile.is_zipfile() (GH-134250)
bpo-28494: Improve zipfile.is_zipfile reliability
The zipfile.is_zipfile function would only search for the EndOfZipfile
section header. This failed to correctly identify non-zipfiles that
contained this header. Now the zipfile.is_zipfile function verifies
the first central directory entry.
Changes:
* Extended zipfile.is_zipfile to verify zipfile catalog
* Added tests to validate failure of binary non-zipfiles
* Reuse 'concat' handling for is_zipfile

Extension builders must specify Py_GIL_DISABLED if they want to link to the free-threaded builds.
This was usually the case already, but this change guarantees it in all circumstances.
