Properly initialize the palette for while on black even on 1bpp framebuffer.
Preparing for demonstration in Open Source Conference 2013 Kyoto.
Fix off by one in copyrows() backward case.
Make omrasops copycols() op work even if columns are not 32 bit aligned.
This means command line editing works properly in any cases.
The bitcopy strategies for 1bpp copycols() op are taken from
recently fixed MI sys/dev/rasops/rasops_bitops.h.
GETBITS() and PUTBITS() m68k asm macro are taken from hp300.
Tested on both 1bpp (on LUNA-II) and 4bpp (on LUNA) framebuffers.
Initialize capabilities in struct wsscreen_descr per omrasops settings.
Now REVERSE characters are drawn properly.
Add preleminary support of 4bpp LUNA framebuffer.
Changes details:
- prepare and switch 4bpp rasops functions that read/write all 4 planes
  and also handle both fg and bg colors
- make 1bpp ops use first plane on write rather than common bitmap plane
  (which is prepared for multiple plane write with raster ops)
- prepare 4bpp allocattr function to handle ANSI 16 color text
- split omrasops_init() function for each bpp
- move struct hwcmap from softc to hwdevconfig to sync palette values
  on initialization
- allow mmap(2) against all available planes
Now we can use ANSI 16 color text console and also can
demonstrate mlterm-fb with color sixel graphics and wallpaper.
XXX: Xserver needs much more work.
Pull a fix of Bt458 (8bpp framebuffer) initialization from OpenBSD/luna88k.
http://marc.info/?l=openbsd-cvs&m=138838884202196
> Correct initialization of Bt458, used in LUNA's 8bpp frame buffer.
>
> According to the manual, the address register does not automatically
> increment when we access to the control registers.  Also we disable
> overlay planes, because we do not use them.
