* Change the calling convention of the device mmap entry point to
pass a vm_offset_t instead of an int for the offset allowing
devices with a larger memory map than (1<<32) to be supported

These changes are required to allow the X server to mmap the various
I/O regions used for device port and memory access on the alpha.
- Express various sizes in bytes, rather than Kbytes, in the video
mode and adapter information structures.
- Fill 0 in the linear buffer size field if the linear frame buffer
is not available.
- Remove SW_VESA_USER ioctl. It is still experimetal and was not meant
to be released.
- Fix missing cast operator.
- Correctly handle pointers returned by the VESA BIOS. The pointers
may point to the area either in the BIOS ROM or in the buffer supplied
by the caller.
- Set the destructive cursor at the right moment.
- there were too many global variables (there still are :-).
- the data section was bloated by explicit initializations of static
variables to 0 (only fixed the recently changed ones).
- WRAPHIST() had silly parentheses around foo->bar.
- the comment about inline functions was stale.
- the comment about Userconfig presumes too much about the boot environment.
- `i' was reused confusingly in scioctl().
- the declaration of `butmap' used a deprecated K&R misfeature.
- the initializeation of `butmap' had an unnecessary line break.
- `unsigned char' was not consistently (mis)spelled as u_char.
- English was poor in a comment in videoio.c.

- Handle pixel (raster text) mode properly.
- Clear screen and paint border right.
- Paint text attribute (colors).
- Fix off-by-one errors.
- Add some sanity checks.
- Fix some function prototypes.
- Add some comment lines.
- Define generic text mode numbers so that the user can just give
"80x25", "80x60", "132x25"..., rather than "VGA_xxx", to `vidcontrol'
to change the current video mode. `vidoio.c' and `vesa.c' will map
these numbers to real video mode numbers appropriate and available
with the given video hardware. I believe this will be useful to make
syscons more portable across archtectures.

The VESA support code requires vm86 support. Make sure your kernel

If you want to statically link the VESA support code to the kernel,
add the following option to the kernel configuration file.
options "VESA"
The vidcontrol command now accepts the following video mode names:
VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600
The VESA_800x600 mode is a raster display mode. The 80x25 text will
be displayed on the 800x600 screen. Useful for some laptop computers.
vidcontrol accepts the new `-i <info>' option, where <info> must be
either `adapter' or `mode'. When the `-i adapter' option is given,
vidcontrol will print basic information (not much) on the video
adapter. When the `-i mode' option is specified, vidcontrol will
list video modes which are actually supported by the video adapter.

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.
the screen mode is changed even if another vty has larger size.
Reallocate the buffer only when the new screen size is larger than
the current cut buffer size.
When bell is of "quiet" types, the console won't ring (or flush)
if the ringing process is in a background vty.

FreeBSD/alpha. The most significant item is to change the command
argument to ioctl functions from int to u_long. This change brings us
inline with various other BSD versions. Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.
The prototype FreeBSD/alpha machdep will follow in a couple of days
time.
- Set the correct value scp->font_size in init_scp().
- Set scp->font_size to FONT_NONE for VGA_MODEX.
Interim fix for a font problem:
- A kludge to display the correct font on some video cards.
We should be able to load multiple fonts to the VGA plane #2 and switch
between fonts by setting the font select register in the VGA sequencer.
It appears that the current code isn't functioning as expected on
some VGA cards (I have reports on Millenium and Mach64 cards). This is
either a bug in syscons or a hardware compatibility problem ;-<
This kludge will always load only one font set at a time and always use
the font page #0 on the plane #2. It is an interim kludge until
we find the exact cause and solution.
Small adjustment for mouse cursor handling:
- Turn off the mouse cursor early when changing video modes.
Video mode switch fixes:
- Stop the screen saver when changing video modes.
- Enclose the critical section with a pair of spltty()/splx().
- A kludge to prevent scrn_update() from accessing video memory in less-
critical sections in video mode change; artificially turn on the
UNKNOWN_MODE flag.
