Xorg for amiga via wsfb. Currently available on CV64 and CV64/3D. More
graphics cards will follow, when adding wscons support to them.

I didn't manage to make the "wskbd" protocol the default in the X server,
so you have to provide a small xorg.conf with Option "Protocol" "wskbd".
The standard protocol will not work as the Amiga wskbd cannot be switched
into raw mode and has no AT-scancode translation in the kernel.

On the positive side, wskbd also works with national keymaps under X.

The graphics modes can still be defined via grfconfig(8). Xorg's wsfb
driver uses the current grf video mode, which is usually mode #1.
All resolutions and depths seem to work (tested on CV64).

Refactoring MD segment related definitions on m68k ports:
- move macro SEGSHIFT, NBSEG, and SEGOFSET from <machine/param.h>
to <m68k/pmap_motorola.h> where they should belong
- also simplify NBSEG macro for both 020/030 and 040/060 cases
- also move m68k_trunc_seg(), m68k_round_seg(), and m68k_seg_offset()
(that use SEGOFSET) from <m68k/param.h> to <m68k/pmap_motorola.h>
- add comments about each segment size value used on pmap_motorola
implementation
- add TIA_SIZE, TIA_SHIFT, TIB_SIZE, and TIB_SHIFT macro which can be
used for ste/pte index sizes
- use proper vaddr_t cast instead of unsigned for SEGOFSET/PGOFSET macro

Tested on atari, hp300, and news68k.

Fix wrong NBSEG values for all hp300 pmap derived m68k ports.
They were incorrect since 1997 on amiga and atari, and since 2002
on other ports, but fortunately they don't look so fatal.

Anyway, these values will be moved into <m68k/pmap_motorola.h> soon
since they are quite pmap implementation dependent.

Move the definition of MSGBUFSIZE up to the machine-arch level if
possible. Pointed out by Bernd Ernesti.

Implement the kernel part of pr-1891. This allows for a more flexible sized
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

- Cleanup for -Wall and -Wstrict-prototypes

add _MACHINE and _MACHINE_ARCH, which are like MACHINE and MACHINE_ARCH,
execpt without quotes. meant to be __CONCAT()ted for easy #includes
of machine-dependent headers for MI code (e.g. for the MI ISA/EISA/PCI/TC
bus code).

Clean up tabbing/spacing in defns of MACHINE, MACHINE_ARCH, and MID_MACHINE.

KERNEL -> _KERNEL

don't be so quick to cast macro arguments to unsigned; if the
arguments are really off_t's (e.g. to btodb), then you can lose
information. This was the "> 4G file systems don't work" bug; physio
uses btodb, which was broken.

Many changes from osymh@gemini.oscs.montana.edu (Michael L. Hitch)
Now use amiga HW for soft interrupts, non-contig options (2 or many chunks),
interrupt handler lists, 4066 ethernet, 1291 scsi, option to defer level 6
interrupts to level 4 (deal with icky built-in serial port)

add USPACE

started out cleaning up amiga_init.c ended up touching alot of files.

resistance is futile, you will be assimilated.
amiga goes: config.new *and* /sys/scsi.
clock code coerced into a single .c file adding an accurate usec delay().
disklabel.c updated to DTRT, code to write RDB's to be added soon.
sbic (old scsi) converted over to new scsi and config this covers about
90% of users. Other drivers soon.

also conform to standard style

protect against multiple inclusion (and be consitent)

add some very usefull debug stuff to spl inline macros.

Move some arch dependant stuff in here.

Add missing Id's

Updated headers from current amiga branch.

new tree for amiga, replacing the bogous previous one.
SunOS support works for a lot of executables now (static and dynamic).

new source release integrated from amiga-release.
