Add a font width argument to vi_load_font_t, vi_save_font_t and vi_putm_t
and do some preparations for handling 12x22 fonts (currently lots of code
implies and/or hardcodes a font width of 8 pixels). This will be required
on sparc64 which uses a default font size of 12x22 in order to add font
loading and saving support as well as to use a syscons(4)-supplied mouse
pointer image.

function pointer to the vga render dispatch table and initialized it with
vga_nop.  The problem is that vga_nop() is a varargs function, and the
table declares a non-varargs function pointer.  On amd64 (and I think ppc),
mixing varargs and non-varargs function pointers is fatal.

Change vga_nop() and gfb_nop() from varargs to non-varargs do-nothing
functions.  This stops the stack corruption that only happened on amd64.

compilation after sys/dev/syscons/syscons.h rev. 1.83.

which doesn't assume a hardware cursor on __sparc64__ rather than on
DEV_CREATOR. If we want to include more than one framebuffer driver in
e.g. the GENERIC kernel all drivers have to work the same way. Now that
DEV_CREATOR is no longer used remove it from options.sparc64.

Took the opportunity to reduce

 __i386__ || __ia64__ || __amd64__ || __sparc64__ || __powerpc__

 to

 !__alpha__

  gfb_draw if 'flip' is specified.  This causes the mouse cut region
  to be displayed in reverse color so it is visbile.
- Use the "other" implementation of gfb_cursor for the creator driver,
  which doesn't assume there is a hardware cursor.  It seems that the
  hardware cursor that creator provides doesn't display the character
  under the cursor in reverse colors, so the driver does this manually
  and uses the hardware cursor for the mouse pointer (which it also works
  much better for).  This is wedged here because it required less hoops
  than accessing the syscons vtb from inside the video driver, which is
  needed to read the character and color attributes under the new cursor
  position.
