tried to clean another bunch of cppcheck warnings

so "funny" thing with cppcheck
is that no 2 versions give the same list of warnings.

On Mac, I'm using v1.81, which had all warnings fixed.
On Travis CI, it's v1.61, and it complains about a dozen more/different things.
On Linux, it's v1.72, and it finds a completely different list of a half dozen warnings.

Some of these seems to be bugs/limitations in cppcheck itself.
The TravisCI version v1.61 seems unable to understand %zu correctly, and seems to assume it means %u.
