All of these fall into the trivial category: loops over (readily made) const local containers. As such, they cannot possibly depend on the safety copy that Q_FOREACH performs, so are safe to port as-is to ranged for loops. There may be more where these came from, but these were the ones that stood out as immediately obvious when scanning the 100s of uses in qtbase, so I preferred to directly fix them over white-listing their files with QT_NO_FOREACH (which still may be necessary for some files, as this patch may not port all uses in that file).
