- Split syscons source code into manageable chunks and reorganize
some of complicated functions.
- Many static variables are moved to the softc structure.
- Added a new key function, PREV. When this key is pressed, the vty
immediately before the current vty will become foreground. Analogue
to PREV, which is usually assigned to the PrntScrn key.

- Modified the kernel console input function sccngetc() so that it
handles function keys properly.
- Reorganized the screen update routine.
- VT switching code is reorganized. It now should be slightly more
robust than before.
- Added the DEVICE_RESUME function so that syscons no longer hooks the
APM resume event directly.
- New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING,
SC_NO_HISTORY and SC_NO_SYSMOUSE.
Various parts of syscons can be omitted so that the kernel size is
reduced.
SC_PIXEL_MODE
Made the VESA 800x600 mode an option, rather than a standard part of
syscons.
SC_DISABLE_DDBKEY
Disables the `debug' key combination.
SC_ALT_MOUSE_IMAGE
Inverse the character cell at the mouse cursor position in the text
console, rather than drawing an arrow on the screen.

SC_DFLT_FONT
makeoptions "SC_DFLT_FONT=_font_name_"
Include the named font as the default font of syscons. 16-line,
14-line and 8-line font data will be compiled in. This option replaces
the existing STD8X16FONT option, which loads 16-line font data only.
- The VGA driver is split into /sys/dev/fb/vga.c and /sys/isa/vga_isa.c.
- The video driver provides a set of ioctl commands to manipulate the
frame buffer.
- New kernel configuration option: VGA_WIDTH90
Enables 90 column modes: 90x25, 90x30, 90x43, 90x50, 90x60. These
modes are mot always supported by the video card.

- The header file machine/console.h is reorganized; its contents is now
split into sys/fbio.h, sys/kbio.h (a new file) and sys/consio.h
(another new file). machine/console.h is still maintained for
compatibility reasons.
- Kernel console selection/installation routines are fixed and
slightly rebumped so that it should now be possible to switch between
the interanl kernel console (sc or vt) and a remote kernel console
(sio) again, as it was in 2.x, 3.0 and 3.1.
- Screen savers and splash screen decoders
Because of the header file reorganization described above, screen
savers and splash screen decoders are slightly modified. After this
update, /sys/modules/syscons/saver.h is no longer necessary and is
removed.
that doesn't have it. This is achieved by having minimal do-nothing stubs
enabled when there are no bpfilter devices configured.
Driver modules should be built with BPF enabled for maximum
convenience (but can be built without it for maximum performance).

The old VN device broke in -4.x when the definition of B_PAGING
changed. This patch fixes this plus implements additional capabilities.
The new VN device can be backed by a file ( as per normal ), or it can
be directly backed by swap.
Due to dependencies in VM include files (on opt_xxx options) the new
vn device cannot be a module yet. This will be fixed in a later commit.

world breakage (mainly for cross-world cases). The world Makefile
attempts to build tools static so that nonexistent or wrong shared
libraries and interpreters don't get used. This is broken anyway
since the world Makefile doesn't know about svr4_genassym.
Force building svr4_genassym static. This is part of "fixing"
aout-to-elf-build breakage. aout-to-elf-build abuses NOTOOLS to
avoid rebuilding all the aout tools. This saves time and avoids
some complications. However, it breaks all the internal tools --
they get linked to target libraries which might not work. Cases
where the host can run the target's static libraries are "fixed"
by encrufting all Makefiles that build internal tools to build the
tools static.
Don't add .depend to CLEANFILES -- it just breaks the separation of
`make cleandepend' from `make clean'.
Removed some superflous explicit dependencies.

- Store the current video mode information in the `video_adapter' struct.
- The size of the `v_offscreensize' field in the VESA mode information
block is u_int16, not u_int8.
XXX It probably makes sense to have a flag for bsd.kern.mk to avoid these
rules.
XXX IO_NDELAY seems to be the main reason for it, when used in a cdevsw
read or write "flag" context. Perhaps a redundant declaration
somewhere like sys/conf.h might help remove the need for vnode.h in
these device drivers in the first place.

Because of the changes, you are required to update your kernel
configuration file now!
The files in sys/dev/syscons are still i386-specific (but less so than
before), and won't compile for alpha and PC98 yet.
syscons still directly accesses the video card registers here and
there; this will be rectified in the later stages.
