Implementation of peer credentials for Unix sockets
The code in `ucred.rs` is based on the work done in [PR 13](https://github.com/tokio-rs/tokio-uds/pull/13) in the tokio-uds repository on GitHub.
This commit is effectively a port to the stdlib, so credit to Martin Habovštiak (`@Kixunil)` and contributors for the meat of this work. 🥇
Happy to make changes as needed. 🙂

Update `std::os` module documentation.
Adds missing descriptions for the modules `std::os::linux::fs` and `std::os::windows::io`.
Also adds punctuation for consistency with other descriptions.
- Use intra-doc links for `std::io` in `std::fs`
- Use intra-doc links for File::read in unix/ext/fs.rs
- Remove explicit intra-doc links for `true` in `net/addr.rs`
- Use intra-doc links in alloc/src/sync.rs
- Use intra-doc links in src/ascii.rs
- Switch to intra-doc links in alloc/rc.rs
- Use intra-doc links in core/pin.rs
- Use intra-doc links in std/prelude
- Use shorter links in `std/fs.rs`
`io` is already in scope.
