When using stamp, drop attributions other than back and foreground
colors so that stamp is not updated unnecessarily.

Misc style clean up's.
- Introduce and use proper macros.
- Use not ambiguous variable names.
- Unify similar functions as possible as I can.
- G/C unused headers.
- Use #include <dev/rasops/foo.h> instead of "foo.h"
No particular functional changes intended.

Merge rasops_putchar_aa.h into rasops_putchar.h.
Support scaling underline dimensions by font height.

Oops, revert an unintentional change for now.

Stop allocating ri_buf and ri_stamp dynamically. As commented in
rasops.h, it is not safe to use kmem_alloc(9) in rasops_init();
rasops routines can be used for early putchar, which means that
UVM is not fully initialized.

Should fix a problem reported by macallan:
http://mail-index.netbsd.org/tech-kern/2019/08/02/msg025327.html

Instead of using ri_buf, inline function rasops_memcpy32() is
introduced to fill 32bit data efficiently.

Instead of using ri_stamp (per device stamp), stamp_ri is
introduced to distinguish for which device stamp is calculated.

Cosmetic changes. No functional changes.

Switch to per-device stamp, and retire stamp_mutex.

XXX
Bump kernel version after other changes for struct rasops_info.

Misc clean-up's:
- protect private stuff in rasops.h by _RASOPS_PRIVATE
- staticify rasops_copycols() and rasops_isgray[]
- G/C unused extern int cold

Factor out putchar_aa functions into rasops_putchar_aa.h, which includes
the following fixes:

- stop using memset to framebuffer for depth 8
- correctly support non-standard positions/lengths of RGB bits in pixel

Cast attr to uint32_t before right shift to avoid undefined behavior.

Also, misc style/cosmetic changes for clarity.

Fix underline for anti-aliased fonts on 15/16 depth screen.

Factor out putchar and width-optimized putchar functions into
rasops_putchar.h and rasops_putchar_width.h, respectively.

XXX
Possibly, we can do the same for putchar_aa functions. But it is
currently missing for 24-bpp.

Provide and use FONT_GLYPH macro, tiny optimization version of WSFONT_GLYPH.

Misc cleen up:
- Make 32bit mask unsigned
- DPRINTF --> __nothing ifndef DEBUG_RASOPS
- "#ifdef DIAGNOSTIC if (x) panic(); #endif" --> KASSERT(!x);
- KNF

* Cleanup whitespace turds

Fix the unaligned accesses discovered by dbj.

- New option (RASOPS_SMALL) for the tight-fisted.
- Don't use int32_t/u_int32_t unless we must.
- Remove C++ single line comment delimeters that crept in.
- Remove defs pertaining to byte granularity 'ragged-edge' bitmasks.
- Move all declarations of per-depth initialization functions to rasops.h.
- Other minor cleanup.

Assign ownership & copyright to TNF. There is probably a procedure for this
that I am unaware of. Also some KNF.

Innumerable fixes and improvements. README contains list of remaining bugs
that need to be squashed.

Fixed licensing due to a foobar on my behalf.

Initial import of 'rasops', the new raster operations set for wscons/rcons.
