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.

[3.13] gh-135307: Fix email error when policy max_line_length is set to 0 or None (GH-135367)

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.
* gh-90949: add Expat API to prevent XML deadly allocations (CVE-2025-59375) (#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)`.
