Merge #3220

3220: Fix clippy warnings, update Cargo.toml versions r=matklad a=SomeoneToIgnore

In the `cargo xtask lint` ouptut, there were two interesting Clippy warnings that might be interesting to investigate further:

* warning: this argument (4 byte) is passed by reference, but would be more efficient if passed by value (limit: 8 byte)

* warning: large size difference between variants
