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

__unused removal on arguments; approved by core.

-Wextra fixes

Remove (the default) #define XXXDEBUG and add the options to the relevant
files.xxx file.

Add "name" parameter to powerhook_establish, to aid debugging. No objections

Add an extra cookie to the ioctl and mmap wsdisplay accessops that points
to the screen on which they are being called. The driver cannot guess
this by itself but it is needed to implement, at least, the getwschar and
putwschar functions in the correct place. There are no functional changes
yet.

Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64.
Suggested and reviewed by macallan@.

Use device_private().

merge ktrace-lwp.

For HPCFB_CLASS_RGBCOLOR class propagate r/g/b widths and positions
from hf_rgb to rasops_info.

No 0x in front of %p...

nuke trailing whitespace

Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

struct proc * -> struct lwp *

Use aprint_normal() in cfprint routines.

Add trailing ; to CFATTACH_DECL.

G/c static pow() function that was used to calculate (2^x) only; replaced
the two instances with equivalent (1<<x).

Use CFATTACH_DECL().

Declare all cfattach structures const.

Don't include <sys/map.h>.

BUGFIX: WSDISPLAYIO_SVIDEO and WSDISPLAYIO_GVIDEO don't work.

alloc_attr -> allocattr

Approved by Matthias Drochner.

Use symbolic WSCOL_* colour names instead of magic numbers.

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.
