sys: Split struct device into a private device_impl.h.

Include this only inside autoconf itself, and a few files that abuse
autoconf in ways I can't confidently make easy fixes for.

sys: Split struct device into a private device_impl.h.

autoconf in ways I can't confidently make easy fixes for.

XXX kernel ABI change requires bump -- no more use of struct device
internals allowed, previously done by some drivers

Merge thorpej-cfargs2.

The Amiga and Atari ports abuse some autoconfiguration internals as part
of their early console bring-up, so we need to expose some of the new
internals to them and adapt the call sites.

src is too big these days to tolerate superfluous apostrophes. It's
"its", people!

Make Amiga video drivers work again after device/softc changes.
Patch from chs@.

split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

Amiga wscons/Xorg support, first phase.
Implemented wscons for CV64 and CV64/3D. Other graphics cards drivers are
prepared for it, but will not be attempted before Xorg is not running.
The wscons support is disabled by default. A GENERIC kernel should behave
like always. Use WSCONS to try out a kernel with wscons support.
Done by rkujawa@ and phx@.

Make the various graphics card drivers compile again.
Use casts to char* before pointer arithmetic.
Try to preserve `volatile' qualification where possible, though
uses of kvtop(), strcpy(), copyin() and copyout() gain an unfortunate
but probably unavoidable __UNVOLATILE().
Correct various instances of "void *ba, fb" to have * in front of fb as well.
Remove some redundant parenthesis pairs in some of the vga* macros.

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

merge ktrace-lwp.

Fix some shadowing of variables

The Double-Semi-Colon Police.

Use aprint_normal() for cfprint routines.

Use CFATTACH_DECL().

Declare all cfattach structures const.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.

"wierd" is weird.
