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.

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.
Change the ELF registration/unregistration scheme to be less error prone.
Adding a new brand requires a single addition to linux_brandlist instead of
modifying linux_load(), linux_unload(), and linux_elf_init().

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.

Honor LDFLAGS for building internal tools. (Tools should normally
be built static to avoid problems with picking up target shared

not quite correct, because the Makefiles in lkm/syscons don't set up the
`machine' symlink, but other, more volatile headers in <machine> are
already used.
screen size was changed while the screen saver was inactive. Adjust
the positions of the daemon and the text and clip them accordingly
each time.
- Don't call set_border() too often. Some video chip may produce
flicker.

- Don't fill the entire screen with blank char every time the saver is
called. Blank only the part of the screen where the daemon and the
text was previously printed.
PPP_DEFLATE options... The code uses #if defined(PPP_DEFLATE) etc, so the
original method of "#define PPP_DEFLATE 0" did not actually disable
anything. It was not possible to configure out bsdcomp or zlib
compression. Also, join the settings for PPP_FILTER and NBPFILTER together
since they are related here (can't have PPP_FILTER without NBPFILTER).
savers are also modified so that they behave in the same way as the
blank saver on MDA and CGA, although it's not the way these screen
savers are supposed to work, but fading monitor and tickling green
monitor cannot be done on MDA and CGA, AFAIK. So, this is the second
best solution.
As of this change, the current state of support of screen savers is
summarized in the following table.
MDA CGA EGA VGA
blank OK OK NA OK
daemon OK OK OK OK
fade * * NA OK
green * * NA OK
snake OK OK OK OK
star OK OK OK OK
OK: works
NA: doesn't work, the module cannot be loaded for this adapter.
*: behave the same way as the blank saver.
As you can see, EGA is left out for now. But, we can do no better, as
EGA registers cannot be read...

facilitate the new saver loading/unloading notification interface
in syscons.
daemon_saver:
- M_NOWAIT was wrong, since NULL returns are not handled. Just use
M_WAITOK.
- use `ostype' instead of hard-coded "FreeBSD". Now there is no more
hard-coded string! (But, who will run this screen saver on other
OS?!)
- put macros and data declarations in a consistent order.
- -DDEAMON_ONLY and -DSHOW_HOSTNAME options added in the previous commit
are removed. Options of this kind can go stale and no one notices
because no one uses them. DEAMON_ONLY is just removed. SHOW_HOSTNAME
is made default.
snake_saver:
- use `ostype' and `osrelease' as in the daemon saver. The string changes
slightly - there was a hyphen after "FreeBSD"; now there is a space.
(It is consistent with uname -a, like the daemon server already is.)
all screen savers:
- Use the new add_scrn_saver()/remove_scrn_saver() in syscons.c
to declare loading/unloading of a screen saver. Removed reference
to `current_saver' and the variable `old_saver' as they are not
necessary anymore.
- The blank, fade and green screen savers manipulate VGA registers.
Module loading should fail for non-VGA cards.
- `scrn_blanked' is consistently treated as a number/counter rather
than boolean.
- Some savers touch `scp->start' and `scp->end' to force entire screen
update when stopping themselves. This is unnecessary now because
syscons.c takes care of that.
- cleared up many unused or unnecessary #include statements.
- Removed -DLKM from Makefiles.
YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THIS CHANGE.

Use the name argument almost the same in all LKM types. Maintain
the current behavior for the external (e.g., modstat) name for DEV,
EXEC, and MISC types being #name ## "_mod" and SYCALL and VFS only
#name. This is a candidate for change and I vote just the name without
the "_mod".
Change the DISPATCH macro to MOD_DISPATCH for consistency with the
other macros.
Add an LKM_ANON #define to eliminate the magic -1 and associated
signed/unsigned warnings.
Add MOD_PRIVATE to support wcd.c's poking around in the lkm structure.
Change source in tree to use the new interface.
