gh-69686: Remove untrue part of `__import__` replacement docs (GH-143261)
Remove untrue part of `__import__` replacement docs
The original statement effectively says that replacing `__import__` at global scope affects import statements, and not only that, but only import statements within the rest of the executing module. None of that has been true since at least Python 2.7, I think.
This was likely missed in python/cpython#69686.

The unknown-8bit trick was designed to deal with unknown bytes in an
ASCII message, and it works fine for that. However, I also tried to
extend it to handle bytes that can't be decoded using the charset
specified in an encoded word, and there it fails because there can be
other non-ASCII characters that were *successfully* decoded. The fix is
simple: do the unknown-8bit encoding using the utf-8 codec. This is
especially appropriate since anyone trying to do recovery on an unknown
byte string will probably attempt utf-8 first.

Count the number of Element attribute accesses as a proxy for work done.
With double the amount of work, a ratio of 2.0 indicates linear scaling
and 4.0 quadratic scaling. Use 3.2 as an intermediate threshold.

gh-143010: Prevent a TOCTOU issue by only calling open once (GH-143011)
RDM: per AZero13's research the 'x' option did not exist when this code was written, This
modernization can thus drop the fd trick in _create_carefully and just use open with 'x' to achieve the same goal more securely.

gh-70647: Better promote how to safely parse yearless dates in datetime. (GH-116179)
* gh-70647: Better promote how to safely parse yearless dates in datetime.
Every four years people encounter this because it just isn't obvious.
This moves the footnote up to a note with a code example.
We'd love to change the default year value for datetime but doing
that could have other consequences for existing code. This documented
workaround *always* works.
* doctest code within note is bad, dedent.
* Update to match the error message.
* remove no longer referenced footnote
* ignore the warning in the doctest
* use Petr's suggestion for the docs to hide the warning processing
* cover date.strptime (3.14) as well

If *a* is an integer, the sign of *a* is discarded in the C source code. Clarify this behavior to prevent foot guns, where a common use case might naively assume that flipping the sign will produce different sequences (e.g. for a train/test split of a synthetic data generator in machine learning).
