f11d6ec503 More fixes to deal with fonts:
- 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.

* Figure out UTC relative to boottime.  Four new functions provide
      time relative to boottime.

    * move "runtime" into struct proc.  This helps fix the calcru()
      problem in SMP.

    * kill mono_time.

9b703b1455 Eradicate the variable "time" from the kernel, using various measures.
"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.

Most uses of time.tv_sec now uses the new variable time_second instead.

gettime() changed to getmicrotime(0.

Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).

A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.

Add a new nfs_curusec() function.

Mark a couple of bogosities involving the now disappeard time variable.

Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.

Change profiling in ncr.c to use ticks instead of time.  Resolution is
the same.

Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call
hzto() which subtracts time" sequences.

Don't touch the hardware when machdep.i8254_freq is being changed but
the maximum count wouldn't change.  This fixes jitter of up to 10 msec
for most small adjustments to machdep.i8254_freq.  When the maximum

this using option "-b" to the boot blocks.  It is smartest to compile
a font into your kernel (See LINT), but not mandatory, but apart from
the cursor you will see nothing on the screen until you load a font.

This mode allows XF86_VGA16 to run in 800x600 mode on otherwise unsupported

34f61944a9 - Move the mouse cursor to the center of the screen after video
mode switch in ioctl.
Possibly related to PR: kern/4271

- A kludge: initialize scp->xpixel and ypixel even in the text mode.
If the console enters the `unknown' graphics mode via the ioctl KDSETMODE
(KD_GRAPHICS), these fields are not set (because syscons cannot know
the correct values), but set_mouse_pos() need to refer to these field
to adjust the mouse position.

- Turn off MOUSE_VISIBLE when switching video mode by ioctl.

- another new option: SC_MOUSE_CHAR
Define the first character code of four consecutive codes to be used for
the mouse cursor.  Default codes are 0xd0 through 0xd3.  Beware that
if you decide to use any codes outside the range of 0xc0-0xdf,
the mouse cursor may not look good, because of the way VGA displays
characters in 9-dot-wide character cells.
Requested by several people.

(This patch was tested by a person who recently reported, in the -current
ML, a page fault problem in the kernel (draw_mouse_iamge()) after
X server shutdown. The patch cured his problem.)

3ed12c01d2 Added accent (dead) key support to syscons and kbdcontrol.
With a keymap with accent key definitions loaded to syscons, you press
an accent key followed by a regular letter key to produce an accented
letter.  Press an accent key followed by the space bar to get the
accent letter itself.

Code is based on the ideas and work by jmrueda@diatel.upm.es and
totii@est.is.

PR: i386/4016

console.h
- Defined structures and constants for accent (dead) keys.

syscons.c, kbdtables.h
- When an accent key is pressed, set the corresponding index to
  `accents'.  If the next key is the space key, produce the accent char
  itself.  Otherwise search the accent key map entry, indexed by
  `accents', for a matching pair of a regular char and an accented char.
- Added ioctl functions to set and get the accent key map (PIO_DEADKEYMAP
  and GIO_DEADKEYMAP).

14e5988fe7 - Add support for the following mice to psm/moused/sysmouse:
MS IntelliMouse, Kensington Thinking Mouse, Genius NetScroll,
  Genius NetMouse, Genius NetMouse Pro, ALPS GlidePoint, ASCII
  MieMouse, Logitech MouseMan+, FirstMouse+

- The `psm' driver is made to recognize various models of PS/2 mice
and enable their extra features so that their additional buttons and
wheel/roller are recognized. The name of the detected model will be
printed at boot time.

- A set of new ioctl functions are added to the `psm', `mse' and
`sysmouse' drivers so that the userland program (such as the X server)
can query device information and change driver settings.

- The wheel/roller movement is handled as the `Z' axis movement by the
mouse drivers and the moused daemon. The Z axis movement may be mapped
to another axis movement or buttons.

- The mouse drivers support a new, standard mouse data format,
MOUSE_PROTO_SYSMOUSE format which can encode x, y, and x axis movement
and up to 10 buttons.

/sys/i386/include/mouse.h
- Added some fields to `mousestatus_t' to store Z axis movement
  and flag bits.
- Added the field `model' to `mousehw_t' to store mouse model code.
  Defined model codes.
- Extended `mousemode_t'.
- Added new protocols and some constants for them.
- Added new ioctl functions and structures.
- Removed obsolete ioctl definitions.

/sys/i386/include/console.h
- Added `dz' field to the structure `mouse_data' to pass Z axis movement
  to `syscons/sysmouse'.
- Removed LEFT_BUTTON, MIDDLE_BUTTON and RIGHT_BUTTON.  Use button bits
  defined in `mouse.h' instead.

/sys/i386/isa/psm.c
- Added a set of functions to detect various mice which have additional
  features (wheel and buttons) unavailable in the standard PS/2 mouse.
- Refined existing ioctl functions and added new ones.  Most important
  of all is MOUSE_SETLEVEL which manipulates the output level of the driver.
  While the output level remains zero, the output from the `psm' driver is
  in the standard PS/2 mouse format (three bytes long).  When the level
  is set to one, the `psm' driver will send data in the extended format.
  At the level two the driver uses the format which is native to the
  connected mouse is used. (Meaning that the output from the device is
  passed to the caller as is, unmodified.)  The `psm'  driver will pass
  such extended data format as is to the caller if the output level is
  two, but emulates the standard format if the output level is zero.
- Added kernel configuration flags to set initial resolution
  (PSM_CONFIG_RESOLUTION) and acceleration (PSM_CONFIG_ACCEL).
- Removed the compile options PSM_ACCEL, PSM_CHECKSYNC and PSM_EMULATION.
  Acceleration ratio is now specified by the kernel configuration flags
  stated above.  Sync check logic is refined and now standard.
  The sync check can be turned off by the new kernel configuration flags
  PSM_CONFIG_NOCHECKSYNC (0x100).  PSM_EMULATION has been of little use.
- Summer clean up :-)  Removed unused code and obsolete comments.

/sys/i386/isa/mse.c
- Created mseioctl() to deal with ioctl functions MOUSE_XXXX.
  Most importantly, the MOUSE_SETLEVEL ioctl will change the
  output format from the 5 byte format to the new, extended format
  so that the caller can take advantage of Z axis movement and additional
  buttons.
- Use constants defined in `mouse.h' rather than magic numbers.

/sys/i386/isa/syscons.c
- Changed scioctl() to reflect the new `console.h' and some of the new
  ioctls defined in `mouse.h'.  Most importantly, the MOUSE_SETLEVEL
  ioctl will change the `sysmouse' output format from the MouseSystems
  5 byte format to the new, extended format so that the caller can
  take advantage of Z axis movement and additional buttons.
- Added support for double/triple click actions of the left button and
  single click action of the right button in the virtual console.  The
  left button double click will select a word under the mouse pointer.
  The triple click will select a line and the single click of the right
  button will extend the selected region to the current position of
  the mouse pointer.  This will make the cut/paste support more compatible
  with xterm.

/sys/i386/isa/kbdio.h
- Added PSM_INTELLI_ID.

totally unfamiliar to it, syscons allows the user to change the
current video mode to some modes which are based on the VGA 80x25
mode. They are VGA 80x30, VGA 80x50, VGA 80x60. In this case the user
will be warned, during boot, that video mode switching is only
paritally supported on his machine.
