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.

Separate general putchar for 1-4bpp from rasops_bitops:
- Support anti-aliasing for 2bpp, which works perfectly!
- Support scaling underline dimensions with font height.

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.

Add general putchar functions for 2 and 4bpp.

Note that 1bpp continues to use its local version in rasops1.c,
which is much faster and simpler.

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[]

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

Fix corruption of background-colored white space and underline when
font width is 8 or 16 on 2bpp screen.

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