saver and splash screen can all work properly with syscons. Note that the splash screen option (SC_SPLASH_SCREEN) does not work yet, as it requires additional code from msmith. - Reorganized the splash screen code to match the latest development in this area. - Delay screen switch in `switch_scr()' until the screen saver is stopped, if one is running, - Start the screen saver immediately, if any, when the `saver' key is pressed. (There will be another commit for `kbdcontrol' to support this keyword in the keymap file.) - Do not always stop the screen saver when mouse-related ioctls are called. Stop it only if the mouse is moved or buttons are clicked; don't stop it if any other mouse ioctls are called. 2. Added provision to write userland screen savers. (Contact me if you are interested in writing one.) - Added CONS_IDLE, CONS_SAVERMODE, and CONS_SAVERSTART ioctls to support userland screen savers. 3. Some code clean-ups.
