Pull the latest OpenBSD sti(4) changes for bitmap framebuffer support.
- bitmap and colormap ops based on old HP ngle X11 driver:
  http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/dev/ic/sti.c#rev1.76
  > Work-in-progress support for non-accelerated X11 on *some* sti(4)
  > frame buffers; based upon the old HP ngle X11 driver.
  > Currently limited to CRX (720/735/750), Timber (710, old 715),
  > Artist (712, 715) and EG (B-series), however the
  > colormap isn't set up correctly on Timber and EG yet.

  > Joint work with Artem Falcon, now in good enough shape to be worked further

The MD hp300 attachment for SGC CRX (A1659-66001) will be committed
separately.

Add bitmap access ops support for SGC CRX (A1659-66001) framebuffer.
Also modify existing 425e EVRX attachment to use updated MI sti(4) ops
more efficiently.

The Xorg server and mlterm-wscons (that support wsdisplay bitmap) work
fine on SGC hp425t.

Special thanks to Miod Vallat again, for contributing the SGC CRX
framebuffer with the SGC connector and flexible cable for HP9000/425t.

He also contributed DIO-II "Hyperion" monochrome framebuffer and
1 plane grayscale SGC GRX (A1924-66001), and I've confirmed hyper(4)
just works even with Xorg server.  I will try GRX as the next project.

Handle WSSCREEN_REVERSE properly.  Based on OpenBSD's sti(4).

Also remove WSSCREEN_UNDERLINE from capabilities that is not handled
by sti(4) ROM routines.

Tested on HP9000/425t with CRX.

Ignore WSDISPLAYIO_PUTCMAP in WSDISPLAYIO_MODE_EMUL, i.e. text mode.

The hardware palette settings are handled by the STI ROM in STI_TEXTMODE
and changing cmap could cause mangled text colors at least on CRX on 425t.

Updating CMAP in EMUL mode isn't expected anyway.

Fixes "red or invisible text" after exiting mlterm-wscons on A1659 CRX.
