`urllib.parse.urlsplit` has already been respecting the WHATWG spec a bit pythonGH-25595.

This adds more sanitizing to respect the "Remove any leading C0 control or space from input" [rule](https://url.spec.whatwg.org/GH-url-parsing:~:text=Remove%20any%20leading%20and%20trailing%20C0%20control%20or%20space%20from%20input.) in response to [CVE-2023-24329](https://nvd.nist.gov/vuln/detail/CVE-2023-24329).

I simplified the docs by eliding the state of the world explanatory
paragraph in this security release only backport.  (people will see
that in the mainline /3/ docs)

Upgrade builds to OpenSSL 1.1.1u.

Also updates _ssl_data_111.h from OpenSSL 1.1.1u, _ssl_data_300.h from 3.0.9.

Manual edits to the _ssl_data_300.h file prevent it from removing any
existing definitions in case those exist in some peoples builds and were
important (avoiding regressions during backporting).
