Fix a few thread-safety bugs to enable test_opcache when run with TSAN:
* Use relaxed atomics when clearing `ht->_spec_cache.getitem`
(gh-115999)
* Add temporary suppression for type slot modifications (gh-127266)
* Use atomic load when reading `*dictptr`
Add a helper for raising DB-API compatible exceptions based on the
result code of SQLite C APIs. Some APIs do not store the error indicator
on the database pointer, so we need to be able to deduce the DB-API
compatible exception directly from the error code.
- rename _pysqlite_seterror() as set_error_from_db()
- introduce set_error_from_code()
GH-127712: Fix `secure` argument of `logging.handlers.SMTPHandler`
Python 3.12 removed support for the `keyfile` and `certfile` parameters
in `smtplib.SMTP.starttls()`, requiring a `ssl.SSLContext` instead.
`SMTPHandler` now creates a context from the `secure` tuple and passes
that to `starttls`.
This fixes UBSan failures for `dbmobject`.
In addition, we perform some minor cleanup changes such as renaming
some `args` parameter to `dummy` in some `METH_NOARGS` methods and
suppressing an unused return value in `_dbm_module_free`.
In case gcc is not available, the test will fail with FileNotFoundError.
So catch the exception to skip the test correctly.

Move pathlib's private `CopyReader`, `LocalCopyReader`, `CopyWriter` and
`LocalCopyWriter` classes into `pathlib._os`, where they can live alongside
the low-level copying functions (`copyfileobj()` etc) and high-level path
querying interface (`PathInfo`).
This sets the stage for merging `LocalCopyReader` into `PathInfo`.
No change of behaviour; just moving some code around.
In `help.copy_strip`, only copy the text `<section>`. In `help.HelpParser.handle_starttag` and elsewhere, remove code to skip the no longer present html. Add a reminder at the top of idle.rst to run copy_strip after changes.

* gh-128657: Run test_hashlib with `--parallel-threads`
This catches the race in `py_digest_by_name` that is fixed separately
in gh-128886.
* Adjust assertion order
Also extend the 'idlelib' section header. These additions affect both the displayed idle.html file and the contents.html file displayed by clicking the Complete table of contents link on the main docs.python.org page. (The module index entries are generated from the module name and synopsis within module files.)
