Change function definitions using the identifier-list form used in the
1st edition of Kernighan and Ritchie's The C Programming Language, to
that of the parameter-type-list form described in the ANSI X3.159-1989
standard.

In ISO/IEC 9899:2023 drafts, there is only one form of function definition.
"N2432 Remove support for function definitions with identifier lists".

ok kettenis@

Implement support for framebuffers that don't start on a page boundary.
This happens on the new 14" and 16" Macbook Pro where we deliberately use
a framebuffer that skips the first few lines to avoid "the notch".
The offset of the first pixel is added to struct wsdisplay_fbinfo. The
stride is added as well, mirroring the value returned by the
WSDISPLAYIO_LINEBYTES ioctl, such that we can retire that one in the
future. A compat ioctl is implemented to help the transition. The compat
code will be removed after OpenBSD 7.3 has been released.

ok miod@

Constify struct cfattach.

ok miod@

Use C99 named initializers for struct wsdisplay_accessops fields.
No functional change.

Sync the sparc64 fb* api with the recent changes done on sparc.

Remove unnecessary <dev/wscons/wscons_raster.h> inclusion.

sbus_establish() and the associated linked list in the sbus softc is now only
used to store a per-device reset callback, for use in sbusreset(). Except
sbusreset() has never, ever, been used since Torek's sbus code went in.
Time to recycle those wasted bits.

Take care of updating the PROMs view of the cursor position in the common fb
code, rather than doing this in only a subset of the fb drivers.

Do not bother passing the blanking routine to fbwscons_console_init(),
as fbwscons_attach() can find it on its own.

Display hardware name and display resolution at attach time, as done on sparc.

Let wsdisplay drivers return zero for WSDISPLAYIO_[GS]VIDEO ioctls - most
of the work is done in the upper layer, but they get to see the ioctl,
so don't always return an error.

Move the struct wsscreen_descr from a per-driver global to a per-instance
field of the sunfb structure. This allows multiple instances of the same driver,
but with different resolutions (such as a couple of vigra or a TGX cgsix and
a TGX+ cgsix) to use distinct wsscreen_descr structures featuring different
resolution information.

Doing this allows more wsscreen_descr fiddling inside the sparc* fb api,
and results in some code shrinkage (about 4KB on sparc GENERIC).

These don't need linear mappings either.

Switch to fbxxx() API.
cgsix tested and ok jason@, the rest tested by me.

Nuke my clause 3 and 4 (and a couple of files jointly (c) with Theo).

branches: 1.7.2;
map the vid mem based on linebytes and height

Labels must be followed by a statement. (Pointed out by gcc3.)

ok jason@

Register more wsscreen properties to take advantage of wsemul_sun changes.

Update rom cursor position if we're the console framebuffer

Set RI_CLEAR if the card isn't the console framebuffer; based on discussion with miod.

Adapt the framebuffer code to the WSDISPLAY_TYPE constant changes, and
add the necessary magic for wsemul_sun color handling.

Initially based on a patch from jason@, then some tinkering by me.
