Merge remote-tracking branch 'origin/5.6' into 5.7
Conflicts: qmake/library/qmakeevaluator.cpp One side changed the iterator to use ranged-for, the other changed its body; they only conflicted because the latter had to add braces around the body, intruding on the for-line. Trivial resolution. Change-Id: Ib487bc3bd6e3c5225db15f94b9a8f6caaa33456b
