This switches flawfinder's version naming conventions to comply with
Semantic Versioning. We change the first digit to "2" because
there's a subtle change in how CWEs are reported - see the
ChangeLog or documentation for more information.

- snprintf is a useful *countermeasure* for buffer overflows,
and unlike some alternatives it is standard and *widely* available.
(strlcpy/strlcat are useful but not standard and not widely available;
snprintf_s is standard but not widely available).
Historically we warned about snprintf because old systems didn't
implement it correctly, but at this point these old systems are
more historical than anything else.
Instead, let's specifically *mention* snprintf as a recommended
potential solution for buffer overflows.
