The series introduces compile-configuration for diagnostic
messages rate-limiting.

Patch 1 is a tiny cleanup for ratelimiting APIs.
Patch 2 is a fixup for the rate-limiter to adjust to new user-defined
rate-limiting parameters.
Patch 3 introduces build-time rate-limiting controls.
Patch 4 is another tiny cleanup to reduce the amount of code.
