Update POSIX reference URLs to 1003.1-2024. (#1160)

* Update POSIX reference URLs to 1003.1-2024.

Update POSIX reference URLs from pointing to Issue 7, 1003.1-2017, to
now point to the new Issue 8, 1003.1-2024.

* Move some unit tests into `mod tests`.

This moves toward the popular idiom of putting tests in `mod tests`
with `#[cfg(test)]`, and also works around Rust nightly warning about
undocumented constants in the expansion of `#[test]`.
