Implement warning for unused dependencies. This will print a diagnostic for crates which are mentioned as `--extern` arguments on the command line, but are never referenced from the source. This diagnostic is controlled by `-Wunused-crate-dependencies` or `#![warn(unused_crate_dependencies)]` and is "allow" by default. There are cases where certain crates need to be linked in but are not directly referenced - for example if they are providing symbols for C linkage. In this case the warning can be suppressed with `use needed_crate as _;`. Thanks to @petrochenkov for simplified core.
