  Log:
  Incorporated lots of fixes and suggestions from Bruce and changes to
  facilitate the new saver loading/unloading notification interface
  in syscons.
  
  daemon_saver:
  - M_NOWAIT was wrong, since NULL returns are not handled.  Just use
    M_WAITOK.
  - use `ostype' instead of hard-coded "FreeBSD". Now there is no more
    hard-coded string! (But, who will run this screen saver on other
    OS?!)
  - put macros and data declarations in a consistent order.
  - -DDEAMON_ONLY and -DSHOW_HOSTNAME options added in the previous commit
    are removed. Options of this kind can go stale and no one notices
    because no one uses them. DEAMON_ONLY is just removed. SHOW_HOSTNAME
    is made default.
  
  snake_saver:
  - use `ostype' and `osrelease' as in the daemon saver. The string changes
    slightly - there was a hyphen after "FreeBSD"; now there is a space.
    (It is consistent with uname -a, like the daemon server already is.)
  
  all screen savers:
  - Use the new add_scrn_saver()/remove_scrn_saver() in syscons.c
    to declare loading/unloading of a screen saver. Removed reference
    to `current_saver' and the variable `old_saver' as they are not
    necessary anymore.
  - The blank, fade and green screen savers manipulate VGA registers.
    Module loading should fail for non-VGA cards.
  - `scrn_blanked' is consistently treated as a number/counter rather
    than boolean.
  - Some savers touch `scp->start' and `scp->end' to force entire screen
    update when stopping themselves. This is unnecessary now because
    syscons.c takes care of that.
  - cleared up many unused or unnecessary #include statements.
  - Removed -DLKM from Makefiles.
  
  YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THIS CHANGE.
