Andrew Gallant e2860fe037 edition: manual fixups to code
This commit does a number of manual fixups to the code after the
previous two commits were done via 'cargo fix' automatically.

Actually, this contains more 'cargo fix' annotations, since I had
forgotten to add 'edition = "2018"' to all sub-crates.
