gh-106498: Revert incorrect colorsys.rgb_to_hls change (GH-106627)
gh-86618 assumed a-b-c = a-(b+c) = a-d where d = b+d.
For floats 2.0, 1.0, and 0.9999999999999999, this assumption
is false. The net change of 1.1102230246251565e-16 to 0.0
results in division by 0. Revert the replacement. Add test.

gh-103186: Fix or catch 'extra' stderr output from unittests (GH-103196)
Reduce test noise by fixing or catching and testing stderr messages from individual tests.
test_cmd_line_script.test_script_as_dev_fd calls spawn_python and hence subprocess.Popen with incompatible arguments. On POSIX, pass_fds forces close_fds to be True (subprocess.py line 848). Correct the call.
test_uuid.test_cli_namespace_required_for_uuid3: when the namespace is omitted, uuid.main calls argparse.Argument_Parser.error, which prints to stderr before calling sys.exit, which raises SystemExit. Unittest assertRaises catches the exception but not the previous output. Catch the output and test it.
test_warnings.test_catchwarnings_with_simplefilter_error similarly prints before raising. Catch the output and test it.

gh-90876: Restore the ability to import multiprocessing when `sys.executable` is `None` (GH-106464)
Prevent `multiprocessing.spawn` from failing to *import* in environments
where `sys.executable` is `None`. This regressed in 3.11 with the addition
of support for path-like objects in multiprocessing.
Adds a test decorator to have tests only run when part of test_multiprocessing_spawn to `_test_multiprocessing.py` so we can start to avoid re-running the same not-global-state specific test in all 3 modes when there is no need.

We match paths using the `_lines` attribute, which is derived from the
path's string representation. The bug arises because an empty path's string
representation is `'.'` (not `''`), which is matched by the `'*'` wildcard.
