Description
Due to the use of lazy initalization (QDirPrivate::initFileLists()), QDir is not re-entrant. E.g. two threads calling QDir::count() on two independent, but shared, copies of a QDir object will cause a data race.
Acceptance criteria:
- QDir is ported to QExplicitlySharedDataPointer (to get const-correctness)
- all internal lazy evaluation is protected from concurrent access
