[New-bugs-announce] [issue44002] Use functools.lru_cache in urllib.parse instead of 1996 custom caching

[Gregory P. Smith]

New submission from Gregory P. Smith <greg at krypto.org>:

`urllib.parse` has custom caching code for both `urlsplit()` and `quote()`.  From 1996.

https://github.com/python/cpython/commit/3fd32ecd9232fcb041b9f1f7a19a1e7e65cf11a0
https://github.com/python/cpython/commit/74495409861b357d9925937d6576229c74e2550d

with a truthful comment added by Nick in 2010 that we should just use functools.lru_cache.

https://github.com/python/cpython/commit/9fc443cf590c76d4b979c46dc954d3956cee0319#diff-b3712475a413ec972134c0260c8f1eb1deefb66184f740ef00c37b4487ef873e

time to clean up this cruft and do that.

I'm waiting for after the 3.10 cut and a still in progress urllib.parse security fix to land before rebasing my soon to be attached PR to avoid code conflicts.
