    Change the choice of invalid screen[] value.
    
    I'm about to use -1 for a different purpose, and in any case it's
    useful to define a properly named macro for any magic value like this
    rather than repeating it more than once in the source.

    Support showing and hiding the cursor.
    
    Previously, IPBT tracked the cursor position by intercepting the
    terminal's calls to the front end's sys_cursor function, which is
    really intended to help screen-reader software and doesn't include
    any parameter to say whether the cursor is actually visible.
    
    Now we do it the same way a real screen _redraw_ would: we notice when
    we see one of the TATTR_* cursor attributes in a call to do_text, and
    if we do, that's where the cursor is. And if we get through a whole
    screen redraw without ever seeing that, then the cursor must not
    currently be visible, which we pass on to the display code via
    the curses curs_set() function.
    
    The effect should be that if a tty recording uses ESC[?25l to hide the
    cursor (and also ESC[?25h to unhide it again), then that should be
    reflected during ipbt playback.
