Tor Arne Vestbø ce73b4db62 Remove dead code from Qt 4 times
The benefit of keeping this code around was to inspire or inform
changes in the areas to take into account possibly missing features
in Qt 5, but at this point that benefit is questionable. We can
always use the history to learn about missing pieces if needed.
