* Fix `recv_uninit` to handle the `TRUNC` flag. With the `TRUNC` flag, `recv` returns the untruncated length, which may be longer than the provided buffer. Fix `recv_uninit` and `recvfrom_uninit` to handle this case. This mean that `recv_uninit` and `recvfrom_uninit` are unable to return the full untruncated length returned by `recv` with the `TRUNC` flag, however it appears that fixing that may require API changes. Fixes #1153. * Add comments mentioning alternatives.
* 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]`.
