Cleanup: consistently use qPrintable()

Browse source 
Replace constructs of the kind
  s.toUtf8().data(),
  s.toUtf8().constData(),
  s.toLocal8Bit().data(),
  s.toLocal8Bit.constData() or
  qUtf8Printable(s)
by
  qPrintable(s).

This is concise, consistent and - in principle - more performant than
the .data() versions.

Sadly, owing to a suboptimal implementation, qPrintable(s) currently
is a pessimization compared to s.toUtf8().data(). A fix is scheduled for
new Qt versions: https://codereview.qt-project.org/#/c/221331/
