By extending IteratorFlag so that it replaces both QDir::Filter and
QDirIterator::IteratorFlag enums, but with better defaults (based on how
QDir/Iterator is used in 15-20 years worth of code in Qt and KDE).
Make the QDirListing(QDir ~~) ctor private, also change it to use
QDirIterator::IteratatorFlags; it will be used to port existing code.
If QDir is ported to use QDirListing::IteratorFlags, instead of
QDir::Filters, a public QDirListing(QDir) constructor can then be added.
