Corinna Vinschen 3432d6f1f7 Throughout, use FileBothDirectoryInformation info class rather than
FileDirectoryInformation info class to avoid problems with incomplete
	filesystem implementations.  Fix comments accordingly.

	fname->Length to 0 in error case to avoid potential crash in debug
	output.
	(fhandler_disk_file::readdir): Try to speed up the working default case.

	returned by filesystems not implementing FileIdBothDirectoryInformation.

	fs.update is called.  Improve debug output.
