Input server now saves keyboard typematic settings whenever they are modified,
instead of wating until it is shutdown (which never happens, either the
system will crash, or the input_server will stay active after a normal shut down)
Same problems might apply to mouse and keymap settings.
Input server shutdown handling should be reviewed.
