* gnomevfs/Directory.cs: PInvoke the _uri methods directory instead of using the ToString() methods. * gnomevfs/FileInfo.cs: Make the FileInfoNative field internal. * gnomevfs/Gnomevfs.metadata: Hide a bunch of unwanted API. * gnomevfs/Uri.custom: New API. * gnomevfs/Vfs.cs: Idem. svn path=/trunk/gtk-sharp/; revision=38126
