Remove global hwplanecount and use ri_depth in struct rasops instead.

No functional change.

Explicitly limit a number of rasops rows per size of rowattr[].

lunafb: Improve drawing performance using VRAM ROP features.
- Drawing a character on 4bpp normally needs 4 times writes, but by using
VRAM ROP actively, it can be reduced to write only once.
The same goes for copyrows. If the whole row consists of only two colors
(one foreground and one background), it can be copied by reading once and
writing once, regardless of the number of planes. Only if the row consists
of more than two colors, it will be copied plane by plane.
- On 8bpp board, it acts as 4bpp (16 colors).
- On 4bpp board on the real LUNA-I(68030/20MHz), monochrome scroll is about
4 times faster even without asm. Using asm improves it by additional 5%
(asm is enabled by default).
- By tsutsui@-san's report, even color scroll is about about 2 times faster
on his 8bpp board on the real LUNA-II(68040).
This was first developped by Y.Sugahara back in late 2019, and was modified
a lot by me in 2022.

This Makes 4bpp wscons putchar ~30% on LUNA-II.

Also use the similar ROP in 1bpp putchar and cursor functions
and the 1bpp putchar is also ~5% faster.
While here, reduce diffs from OpenBSD a bit.

Tested on all 1bpp/4bpp/8bpp framebuffers.

Add preleminary support of 4bpp LUNA framebuffer.

Changes details:
- prepare and switch 4bpp rasops functions that read/write all 4 planes
and also handle both fg and bg colors
- make 1bpp ops use first plane on write rather than common bitmap plane
(which is prepared for multiple plane write with raster ops)
- prepare 4bpp allocattr function to handle ANSI 16 color text
- split omrasops_init() function for each bpp
- move struct hwcmap from softc to hwdevconfig to sync palette values
on initialization
- allow mmap(2) against all available planes

Now we can use ANSI 16 color text console and also can
demonstrate mlterm-fb with color sixel graphics and wallpaper.
XXX: Xserver needs much more work.

Make omrasops copycols() op work even if columns are not 32 bit aligned.

This means command line editing works properly in any cases.

The bitcopy strategies for 1bpp copycols() op are taken from
recently fixed MI sys/dev/rasops/rasops_bitops.h.
GETBITS() and PUTBITS() m68k asm macro are taken from hp300.

Tested on both 1bpp (on LUNA-II) and 4bpp (on LUNA) framebuffers.

deprecated rcons(4). This allows "options FONT_foo" in kernel config files.
Mostly taken from OpenBSD/luna88k, but unnecessary MI rasops(9) stuff is

Revive NetBSD/luna68k.

Even after almost a lost decade since NetBSD/luna68k was
switched to using ELF format by default back in 2001,
actually only one fix (bus.h) is required for a GENERIC kernel itself
to get multiuser login: prompt on a real hardware. Hurrahhh!!!

Demonstrated with a working Xorg mono server on the NetBSD booth
at Open Source Conference 2011 Kansai @ Kyoto:
http://www.ospn.jp/osc2011-kyoto/

"Very impressed," commented by Tomoko YOSHIDA,
Program Committee Chair of the Conference,
and some other OMRON guys.

Special Thanks to Tadashi Okamura, for providing
a working SX-9100/DT "LUNA" for this mission.


Changes details:

sys/arch/luna68k/include/bus.h
- handle stride properly even on multi and region ops for MI spc(4)
- also fix stride handling of (currently unused) 2 and 4 byte ops

sys/arch/luna68k/conf/Makefile.luna68k
sys/arch/luna68k/conf/kern.ldscript.head
sys/arch/luna68k/conf/kern.ldscript.tail
- build a faked a.out kernel using elf2aout(8) tool
and a linker script derived from cats and shark
for the LUNA firmware that loads a.out binary directly
via network or from a UNIOS partition on a local disk

sys/arch/luna68k/dev/omrasops.c
sys/arch/luna68k/dev/omron_rfont.h
- use the original OMRON font derived from 4.4BSD-Lite/luna68k
rather than gallant19 which is used on Sun workstations
(XXX omrasops.c should be rewritten to use generic wsfont(4))

distrib/luna68k/*
distrib/utils/sysinst/arch/luna68k/*
etc/etc.luna68k/MAKEDEV.conf
etc/etc.luna68k/Makefile.inc
sys/arch/luna68k/conf/INSTALL
- build a ramdisk based INSTALL kernel with sysinst(8) for luna68k
- also build an installation iso image for luna68k

sys/arch/luna68k/conf/GENERIC
- enable SYSVSHM (and other SYSV*) options for Xorg server

More Xorg changes (which need some more cleanup) and
isiboot.c fixes will come soon.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.

Remove clause 3 and 4 from TNF licenses

Use (uint8_t *) for framebuffer address.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
