9917ef17e9 Port syscons to the alpha. The driver itself has moved to sys/isa as it will 
hopefully become a portable driver usable by all architectures.  The api
support files have had to be copied to sys/alpha/include since userland
programs expect to find them in <machine/*.h>.

All the revision history of the i386 syscons has been retained by a
repository copy.

bc008436d8 1. Reorganized screen saver related code so that both the LKM screen 
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.

31a8d7d917 Fix pmap_enter_quick() to stop it hanging when the level 2 pte exists 
but isn't valid.

Reimplement pmap_remove() to be much more efficient at removing large
stretches of addresses.

As part of reimplementing pmap_remove() fix pmap_protect() so that it stands
a hope of working.
