gh-100218: correctly set `errno` when `socket.if_{nametoindex,indextoname}` raise `OSError` (GH-140905)
Previously, socket.if_nametoindex() and socket.if_indextoname() could raise
an `OSError` with a `None` errno. Now, the errno from libc is propagated.

* Document that ensure_ascii=True forces escaping not only non-ASCII, but also
non-printable characters (the only affected ASCII character is U+007F).
* Ensure that the help output for the json module does not exceed 80
columns (except one long line in an example and generated lines).
* Add more tests.

Update selected RFC 2822 references to RFC 5322
RFC 2822 was obsoleted by RFC 5322 in 2008. This updates references
to use the current standard in documentation, docstrings, and comments.
It preserves RFC 2822 references in legacy API components to maintain their
historical context.
RFC 822 → RFC 2822 → RFC 5322 progression is explained where relevant.
In some places specific sections of RFC are referenced where it seems helpful.
Scout rule was applied in some places and RFC mentions format was
normalized in doc strings and comments.

RDM: Like the change made in a earlier PR to the folder, we can/must use 'maxlen' as a stand in for 'unlimited' when computing line lengths when max_line_length is 0 or None; otherwise the computation results in a traceback.

* [3.14] gh-90949: add Expat API to prevent XML deadly allocations (CVE-2025-59375) (GH-139234)
Expose the XML Expat 2.7.2 mitigation APIs to disallow use of
disproportional amounts of dynamic memory from within an Expat
parser (see CVE-2025-59375 for instance).
The exposed APIs are available on Expat parsers, that is,
parsers created by `xml.parsers.expat.ParserCreate()`, as:
- `parser.SetAllocTrackerActivationThreshold(threshold)`, and
- `parser.SetAllocTrackerMaximumAmplification(max_factor)`.

gh-140082: Forward colorizing from libregrtest to unittest (GH-140083)
libregrtest redirects test output to a file as part of its operation.
When `unittest` checks to see if it should colorize with
`isatty(sys.stdout)` that fails resulting in no colorizing of the
unittest output.
Update `libregrtest` to set `FORCE_COLOR=1` when redirecting test output
so that unittest will do color printing.
