gh-100176: venv: Remove redundant compat code for Python <= 3.2 (#100177) 
gh-100176: Remove redundant compat code for Python 3.2 and older

Python 3.2 has been EOL since 2016-02-20 and 2.7 since 2020-01-01, so we
can remove this old compatibility check and unindent the old else-block.

Also, in the unindented block, replace a .format() call with an f-string.

Plus similar changes in the documentation.

gh-81057: Move _Py_RefTotal to the "Ignored Globals" List (gh-100203) 
We can't move it to _PyRuntimeState because the symbol is exposed in the stable ABI. We'll have to sort that out before a per-interpreter GIL, but it shouldn't be too hard.

Fix: typo (Indention) (GH-99904)

gh-88500: Reduce memory use of `urllib.unquote` (#96763) 
`urllib.unquote_to_bytes` and `urllib.unquote` could both potentially generate `O(len(string))` intermediate `bytes` or `str` objects while computing the unquoted final result depending on the input provided. As Python objects are relatively large, this could consume a lot of ram.

This switches the implementation to using an expanding `bytearray` and a generator internally instead of precomputed `split()` style operations.

Microbenchmarks with some antagonistic inputs like `mess = "\u0141%%%20a%fe"*1000` show this is 10-20% slower for unquote and unquote_to_bytes and no different for typical inputs that are short or lack much unicode or % escaping. But the functions are already quite fast anyways so not a big deal.  The slowdown scales consistently linear with input size as expected.

Memory usage observed manually using `/usr/bin/time -v` on `python -m timeit` runs of larger inputs. Unittesting memory consumption is difficult and does not seem worthwhile.

Observed memory usage is ~1/2 for `unquote()` and <1/3 for `unquote_to_bytes()` using `python -m timeit -s 'from urllib.parse import unquote, unquote_to_bytes; v="\u0141%01\u0161%20"*500_000' 'unquote_to_bytes(v)'` as a test.
