    Suppress various cppcheck warnings
    
    cppcheck is throwing lots of plainly-incorrect false-positive warnings
    for these issues. Sadly, some of these are important warnings, but they
    are just not useful due to all the false positives, so we should
    suppress them.
    
    Hopefully clang's scan-build would be better at avoiding
    false-positives.
