The patch below makes the game backgammon(6) use `const' where

appropriate.  It also removes some obsolete, unused code to check the
number of users on the system (obsoleted by dm); removes a prototype
for an unused function that was removed earlier; and removes a control
character from one message that was I think intended to clear the
screen on some particular terminal (though I can't find the comment to
that effect in any of the BSD source trees I have handy) but no longer
serves any useful purpose.

From PR 6580 by Joseph Myers <jsm28@cam.ac.uk>.

Also contains two more patches, one in teachgammon/tutor.h (by Joseph)
and one in common_source/fancy.c (by me).
