(crate-fetch)[input-crates]: Rename to dev-crates.
[native-input-crates]: Rename to dev-dep-crates.
[inputs]: Rename to cargo-inputs.
[native-inputs]: Rename to cargo-development-inputs.
(maybe-cargo-inputs, maybe-cargo-development-inputs, maybe-arguments): Add
them.
(make-crate-sexp)[inputs]: Rename to cargo-inputs.
[native-inputs]: Rename to cargo-development-inputs.
[maybe-native-inputs, maybe-inputs]: Replace with maybe-arguments.
* guix/import/utils.scm: (package-names->package-inputs): Make public.  Add
docstring.
* tests/crate.scm (crate->guix-package): Update the match pattern.
