The functions for standard file system operations simply delegate to
the static functions in QFileSystemEngine, which are then implemented
separately for each platform. There is no need for the wrappers in
QFSFileEngine to be separately implemented as well.
The only noticeable difference between Unix and Windows versions was
the clearing of the meta data in QFSFileEngine::remove, which was only
done on Unix. This is now also done on Windows.
As a fly-by fix, correct the (internal only) documentation about case
sensitivity.
