    Refactor permissions implementation
    
    Permissions on Windows have been simplified to use the underlying
    Windows API calls rather than the pseudo-POSIX interface (which chokes
    on long paths).
    
    The metadata API has been extended slightly to allow handling of raw
    permission bits (Mode).  Unfortunately, we can't take full advantage of
    it because the existing permissions API is really quirky and
    inconsistent and we have to maintain compatibility.  It's also unclear
    what the ideal mapping between "rwes" and "rwxrwxrwx" should be.
    
    No changes in the semantics of the permissions have been introduced.
