gh-96710: Make the test timing more lenient for the int/str DoS regression test. (GH-96717)

A regression would still absolutely fail and even a flaky pass isn't
harmful as it'd fail most of the time across our N system test runs.

Windows has a low resolution timer and CI systems are prone to odd
timing so this just gives more leeway to avoid flakiness.

gh-95778: Correctly pre-check for int-to-str conversion (GH-96537)

Converting a large enough `int` to a decimal string raises `ValueError` as expected. However, the raise comes _after_ the quadratic-time base-conversion algorithm has run to completion. For effective DOS prevention, we need some kind of check before entering the quadratic-time loop. Oops! =)

The quick fix: essentially we catch _most_ values that exceed the threshold up front. Those that slip through will still be on the small side (read: sufficiently fast), and will get caught by the existing check so that the limit remains exact.

The justification for the current check. The C code check is:
```c
max_str_digits / (3 * PyLong_SHIFT) <= (size_a - 11) / 10
```

In GitHub markdown math-speak, writing $M$ for `max_str_digits`, $L$ for `PyLong_SHIFT` and $s$ for `size_a`, that check is:
$$\left\lfloor\frac{M}{3L}\right\rfloor \le \left\lfloor\frac{s - 11}{10}\right\rfloor$$

From this it follows that
$$\frac{M}{3L} < \frac{s-1}{10}$$
hence that
$$\frac{L(s-1)}{M} > \frac{10}{3} > \log_2(10).$$
So
$$2^{L(s-1)} > 10^M.$$
But our input integer $a$ satisfies $|a| \ge 2^{L(s-1)}$, so $|a|$ is larger than $10^M$. This shows that we don't accidentally capture anything _below_ the intended limit in the check.

gh-90814: Correct NEWS wording re. optional C11 features (GH-96309) (GH-96384)

The previous wording of this entry suggests that CPython
won't work if optional compiler features are enabled.
That's not the case. The change is that we require C11 rather
than C89.

Note that PEP 7 does say "Python 3.11 and newer versions use C11
without optional features." It is correct there: that's
not a guide for users who compile Python, but for CPython devs
who must avoid the features.

gh-95432: Add doctests for the sqlite3 docs (GH-96225)

gh-96021: Explicitly close the IsolatedAsyncioTestCase runner in tests (GH-96135)

Tests for IsolatedAsyncioTestCase.debug() rely on the runner be closed
in __del__. It makes tests depending on the GC an unreliable on other
implementations. It is better to close the runner explicitly even if
currently there is no a public API for this.

gh-95243: Mitigate the race condition in testSockName (GH-96173)

find_unused_port() has an inherent race condition, but we can't use
bind_port() as that uses .getsockname() which this test is exercising.

Try binding to unused ports a few times before failing.

GH-95704: Don't suppress errors from tasks when TG is cancelled (GH-95761)

When a task catches CancelledError and raises some other error,
the other error should not silently be suppressed.

Any scenario where a task crashes in cleanup upon cancellation
will now result in an ExceptionGroup wrapping the crash(es)
instead of propagating CancelledError and ignoring the side errors.

NOTE: This represents a change in behavior (hence the need to
change several tests).  But it is only an edge case.
