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.

Next syscons update (given up on numbering :) Removed screensavers from syscons, they are now LKM's. This makes it possible to do some really "interesting" screensavers... Fixed bug that sometimes caused garbage to appear when leaving "scroll-lock" history. Reformattet indentation, it got too deep for a normal 80 pos screen. Split up in syscons.c & syscons.h for use with the saver-lkm's. Temporarily removed -s option from vidcontrol, savers should now be loaded with modload.

Introducing "Jumping Daemon" screen saver. This is really cute and eye-catching :-) Submitted by: ssigala@globalnet.it Also fixed some `extern' declarations in saver.h.
