    PR modula2/108344 disable default opening of /dev/tty

    This patch changes removes the static initialisation code for
KeyBoardLEDs.cc.
    The module is only initialised if one of the exported functions is call=
ed.
    This is useful as the module will access /dev/tty which might not be
    available.  TimerHandler.mod has also been changed to disable the scroll
    lock LED as a sign of life.
