This is an easy step toward adopting 2018 edition eventually, and will make any future CL that sets `edition = "2018"` this much smaller. The module system changes in Rust 2018 are described here: https://doc.rust-lang.org/edition-guide/rust-2018/module-system/path-clarity.html Generated by running: cargo fix --edition --all in each workspace, followed by bin/fmt.
