Subject: QDirPrivate refactoring

Some renaming to make intent clearer and improve consistency:

    listsDirty      => listsInitialized (logic inverted)
    updateFileLists => initFileLists
    clear           => clearFileLists

Also note that initializing file lists shouldn't trigger detach, because
no previous version of the cached data has been seen.
