Add dumb framebuffer (no acceleration, no colormap) support
for HP362 and HP382.

Tested on A1473-69510 (HP362 VGA-res) and A1474-69511 (HP382 mid-res).

Pull OpenBSD's standalone ITE driver reorganization:
- merge similar clear, putc, cursor, and scroll ops for all DIO framebuffers
- rename and move hyper_windowmove() to ite_dio_windowmove1bpp()

Pull OpenBSD's standalone ITE driver reorganization:
- merge similar clear, putc, cursor, and scroll ops for all DIO framebuffers
- rename and move hyper_windowmove() to ite_dio_windowmove1bpp()
to use it among all dumb monochrome framebuffers
- ditto hyper_putc() to ite_dio_putc1bpp()
- remove unnecessary flags, macro, function args, and structure members
- remove trailing spaces and tabs

Also misc cosmetics to reduce diffs from OpenBSD,
and some KNF that generates diffs from OpenBSD.

Tested on HP382 and HP425t.

Move and renamve hyper_ite_fontinit() to ite_fontinit1bpp() to share it
among all monochrome framebuffers. Also rename ite_fontinit() to
ite_fontinit8bpp(). From OpenBSD.

All framebuffer drivers use common readbyte and writeglyph functions
so no need to put them into per driver function pointers. From OpenBSD.

Tested on HP382 (serial) and HP425t (topcat).

Resurrect and move retired ITE files that are still used by bootloaders.

merge ktrace-lwp.

Use ANSI function decls.

Misc cleanup:
- KNF
- WARNSfy
- remove __P()
- remove register declarations
- const'ify some variables
- make some local functions/variables static
- bcopy -> memcpy
- bcmp -> memcmp
- bzero -> memse

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

Complete and total reorganization of the hp300 boot code, modeled
closely after the build process used by NetBSD/alpha's boot code.
