Some fixes for cppcheck 1.88
Sergey is looking to update some backends on the test server. This will involve updating the cppcheck version to 1.88.
That newer version catches more things. To avoid perma-failing on the cppcheck, we should address the new issues. I had already updated the known issues list with existing cppcheck 1.88 issues, but a few new ones have slipped through since. I've either just fixed them, or have updated the cppcheck suppression list to simply ignore a style test which doesn't quite match how we use Rosetta.
