... in QCOMPAREs.
The implementation is hidden in a nested Internal namespace that retrieves
the strings without strdup()ing. That makes it easier to compose these
functions as there is no need to delete character arrays when using them.
The public interface (which qstrdup()s) is implemented on top of these.
[ChangeLog][QtTest] QCOMPARE now pretty-prints QSizePolicy{,::Policy,::ControlType{,s}}.
