Printing can be very expensive if it occurs often, so printing that can
be triggered by userspace should be rate limited. For this purpose, add
a Rust wrapper around `struct ratelimit_state` and use it in the new
macros.
The new files will fall under the catch-all RUST maintainers entry.

[ Removed unused link reference definitions. On the `static`, allowed
the `non_upper_case_globals` lint so that `kernel` users (and users
providing their own name) do not warn. Reworded title for typo.
