Subject: Enable rust_2018_compatibility lint

In preparation for the switch to using Rust 2018, this change enables
the rust_2018_compatibility lint. Along with that enablement we fix the
warnings emitted by it, which evolve around the module system changes
Rust has gone through and that require us to prefix initial uses of
crate local modules with "crate".
