Fix wrong checks for some integer config records

[moonchen]

RECC_INT expects a numeric range, and not a regex. Regex should be used with RECC_STR.

1. Fix configs where RECC_INT is used with an invalid range.
2. Add a static_assert so that RECC_INT is always used with a range.
3. Make RECC_INT range check more robust.
4. Add unit tests for range check.
