Summary of the changes:

- Enable spleen8x16 for all architectures, replacing bold8x16_iso1.
- Enable spleen12x24 on all arches but sparc64, replacing gallant12x22.
- Enable spleen16x32 and spleen32x64 on amd64, i386, and arm64 for

- Modify the font selection logic in rasops(9) so the 16x32 and 32x64

- there is no global wsdisplay limit on the number of fonts loaded. Such a
limit will be enforced by the display drivers themselves.
- built-in kernel fonts will now appear in the list of fonts.

Grow a list_font accesop for rasops, which relies upon wsfont_enum(), which

No longer store fonts added with the WSDISPLAYIO_LDFONT ioctl into the
wsdisplay softc. Instead, since the knowledge about available fonts lies in
the parent driver itself, introduce a list_font wsdisplay_accessop which
queries a font index, suitable to use within the WSDISPLAYIO_LSFONT ioctl.

With this in place:
- there is no global wsdisplay limit on the number of fonts loaded. Such a
limit will be enforced by the display drivers themselves.
- built-in kernel fonts will now appear in the list of fonts.

Grow a list_font accesop for rasops, which relies upon wsfont_enum(), which
is turned into something useful (and abortable if you do not need to iterate
further). Not used by any rasops driver yet.

Add a load_font accessop to rasops, to allow for fonts to be loaded and
selected. All rasops fonts are managed by wsfont, which allows a font to be
loaded on a rasops device and used on another.

Currently not plumbed in any driver yet. This is work in progress.

Put the 12x22 font on alpha and macppc installation kernels, the 8x16 font
is really fugly on large displays (tga, vgafb). It's only 10KB more data
before compression, which fits in our floppies.

No longer store fonts added with the WSDISPLAYIO_LDFONT ioctl into the
wsdisplay softc. Instead, since the knowledge about available fonts lies in
the parent driver itself, introduce a list_font wsdisplay_accessop which
queries a font index, suitable to use within the WSDISPLAYIO_LSFONT ioctl.

With this in place:
- there is no global wsdisplay limit on the number of fonts loaded. Such a
limit will be enforced by the display drivers themselves.
- built-in kernel fonts will now appear in the list of fonts.

Grow a list_font accesop for rasops, which relies upon wsfont_enum(), which
is turned into something useful (and abortable if you do not need to iterate
further). Not used by any rasops driver yet.

Add a load_font accessop to rasops, to allow for fonts to be loaded and
selected. All rasops fonts are managed by wsfont, which allows a font to be
loaded on a rasops device and used on another.

Currently not plumbed in any driver yet. This is work in progress.

Replace manual list handling with a TAILQ.

Remove Unicode to ISO-8859-7 translation tables, they would only be used if
one were to use an ISO-8859-7-encoded font on a raster display, yet none of
the fonts the kernel chooses from uses this encoding.

First pass at removing clauses 3 and 4 from NetBSD licenses.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

OK deraadt@

Only the most obvious bzero() -> M_ZERO changes. No cast changes, no

Provide the usual 8x16 font, instead of the qvss 8x15 font, for low-res vax
frame buffers (and smg until it can use non-8bit wide fonts), as the latter
has too many symbols in the 8-bit range stubbed out.

Do not compile non-iso font encoding conversion tables and {bit(*),byte} order
reversal if SMALL_KERNEL. Saves ~5KB before compression.
ok deraadt@

(*) except on alpha because tga needs it.

Add the 12x22 font to vax defaults.

Select the 8x15 font by default on vax.

Stop compiling the texte console rotation code #ifdef __zaurus__, but use
a flag in the rasops_info structure; drivers which may use it shall declare
a specific attribute for the config(8) machinery, so that the necessary code
is compiled in.

In addition to this, rotated font computation is now done on-demand, and a
list of unrotated-rotated font cookie pairs is kept, rather than rotating all
built-in wsfonts at initialization time.

No user-perceptible functional change.

Tested matthieu@ uwe@, ok uwe@

Provide both 8x16 and 12x22 fonts on sparc64 even if SMALL_KERNEL, as
vigra and some cgthree clones might need tho 8x16 font. Fits the floppies,
other architectures unaffected.

Temporary hack to (un)rotate the Zaurus console until a proper rasops
rotation framework is ready.

Make the HAVE_FONT logic work correctly when user requests FONT_BOLD8x16
only.

Remove more '\n's from panic() statements. Both trailing and leading.

Diff generated by Chris Kuethe.

The consensus was to include both FONT_GALLANT12x22 and FONT_BOLD8x16
for sparc, even when SMALL_KERNEL is defined. That way we get a
reasonable font on the sparcbook for the install.

When building kernels with the SMALL_KERNEL option (typically, RAMDISK),
only one wsfont will be included.
Instead of forcing it to be the 8x16 font, choose it depending on the
architecture we are compiling for - this way, sparc* will get the
PROM-like 12x22 font instead.

Restore the support of ISO 8859-1 fonts in macppc console. gallant12x22.h
was updated with the characters from dev/wscons/wscons_gallant19.h.
bold8x16-iso1.h is based on bold8x16.h and the missing characters added
by me. bold8x16-iso1.h isn't used by default. -moj ok @drahn, @miod

use the gallant 12x22 font by default on screens that are more
than 960 pixels wide if !SMALL_KERNEL, like rcons does.

Add "Spleen 6x12" to wsfont, a font targetted at OLED displays.

Similar to "Spleen 5x8" it only contains the printable ASCII

ok jan@, anton@

Enable Spleen in wsfont and modify the font selection logic at runtime
in rasops(9) to allow selecting larger fonts when available.

Summary of the changes:

- Enable spleen8x16 for all architectures, replacing bold8x16_iso1.
- Enable spleen12x24 on all arches but sparc64, replacing gallant12x22.
- Enable spleen16x32 and spleen32x64 on amd64, i386, and arm64 for
GENERIC kernels.
- Modify the font selection logic in rasops(9) so the 16x32 and 32x64
fonts are selected if at least 120 columns can be displayed. Screens
with widths equal or larger than 1920px will use the 16x32 font, and
screens with widths equal or larger than 3840px the 32x64 one.

OK kettenis@, ratchov@, deraadt@

Add Spleen 8x16, 12x24, 16x32, and 32x64 variants to wsfont.

Together with the already imported Spleen 5x8, it will allow using the
same font family across a wide range of screen resolutions, from small
OLED displays to 4K monitors.

The fonts are 2-Clause BSD licensed and are my original creation.

OK jcs@, brynet@, bcallah@, kettenis@

Add "Spleen 5x8" to wsfont, a font targetted at small OLED displays
to be used with devices handled by ssdfb(4). It contains all printable
ASCII characters (96 glyphes).

If you use sys/param.h, you don't need sys/types.h

Backout because it breaks ramdisks. Anyone making changes in the kernel
is required to consider or test ramdisks before commit.

Add compressed fonts support in the kernel.

The wsdisplay_font structure has been modified to add two new members
(zdata and zdata_len) to store compressed font data and its size. We
define compressed fonts by setting the data field to NULL and populating
the zdata and zdata_len fields.

In wsfont_lock(), we check if the selected font needs to be inflated,
and we call the newly introduced wsfont_inflate() if required.

OK kettenis@

Implement counter-clockwise rotation.

ok bcook@, stsp@

Remove qvss8x15, vt220l8x8, and vt220l8x10 fonts.

Those fonts are not compiled in by default, and are smaller than the
smallest font (bold8x16_iso1) we currently include.

OK mpi@, deraadt@

Remove lucida16x29.h and omron12x20 fonts.

- lucida16x29 is a bad conversion from a truetype font, it is too bold
which makes it unreadable.
- omron12x20 is a serif font, and is very difficult to read due to
inconsistencies in character spacing, alignement, and width.

Moreover, both fonts only have 96 glyphs.

No objection from mlarkin@

OK mpi@, jcs@

Remove sony8x16 and sony12x24 fonts.

They were not compiled in by default, and are Serif fonts, which doesn't
work very well for monospaced bitmap fonts intended for console use.

OK mpi@, visa@, jcs@

Remove reference to non existing font.

Include file with font data (courier11x18.h) was removed from NetBSD due
to licensing concerns before wsfont was imported into OpenBSD.

Cookie values have been renumbered for consistency.
