Passing a negative or zero size to `cursor.fetchmany()` made it fetch all rows
instead of none.
While this could be considered a security vulnerability, it was decided to treat
this issue as a regular bug as passing a non-sanitized *size* value in the first
place is not recommended.

* Only lock the SSL context, not the SSL socket.
This solves a deadlock when a socket is blocked while waiting on data,
which ended up causing a major regression in 3.13.6 (see gh-137583).

gh-136914: Fix support of cached functions and properties in DocTest's lineno computation (GH-136930)
Previously, DocTest's lineno of functions and methods decorated with
functools.cache(), functools.lru_cache() and functools.cached_property()
was not properly returned (None was returned) because the
computation relied on inspect.isfunction() which does not consider the
decorated result as a function.
We now use the more generic inspect.isroutine(), as elsewhere
in doctest's logic.
Also, added a special case for functools.cached_property().

There was a deadlock originally seen by Memray when a daemon thread
enabled or disabled profiling while the interpreter was shutting down.
I think this could also happen with garbage collection, but I haven't
seen that in practice.
The daemon thread could be hung while trying acquire the global rwmutex
that prevents overlapping global and per-interpreter stop-the-world events.
Since it already held the main interpreter's stop-the-world lock, it
also deadlocked the main thread, which is trying to perform interpreter
finalization.
Swap the order of lock acquisition to prevent this deadlock.
Additionally, refactor `_PyParkingLot_Park` so that the global buckets
hashtable is left in a clean state if the thread is hung in
`PyEval_AcquireThread`.
