disabled by default, also supports vsync blanking, disabled by default.
aaron@ looked at it a while back and i fixed problems he had indicated.

the wsmoused daemon (replacement for moused which was used with PCVT). Adds
a "getchar" method to the display drivers which returns the value of the
character currently under the cursor (e.g., so it may be inversed). From jbm@.
Still needs a bit of cleanup and improvement, especially X cohabitation
features. The pointer moves to fast as well. These sorts of issues will be
corrected in-tree.

does mapchar for it w /the same success as primary,
prefer secondary mapping. this fixes non-lat char display.

it could be of a different size than 0x8000,
and now bios(4) does it for us the right way.
besides, would the prom be at the same address on non-i386?

the screen was only restored if a new character was actually displayed on the
screen); jcs@rt.fm. This brings us closer to the behavior of PCVT. Also, while
I'm here, add some #ifdef so wskbd does not depend on wsdisplay (pointed out
to me by fgsch@).

files could probably be updated even a bit further (they are from mid-summer).
In addition, I've added support for console scrollback, somewhat inspired by
Linux's vgacon driver. Basically, instead of allocating our own buffer and
doing lots of copies, we take advantage of Video RAM and just modify the VGA
display origin register as appropriate. This approach has a few advantages:
simple to implement, no wasted KVM, it's fast, and after a boot you can now
scroll back all the way to the BIOS messages (assuming your msgbuf is of a
typical length :). Disadvantages are that the VRAM buffer is relatively
small (only 32k) and we do not support raster devices through this method.
(thanks to mickey@ for pointing this out).
The code for this is fairly unobtrusive, so should we come up with a better
approach to console scrollback at a later time (i.e., even more platform
independent) it should be easy to revert this.
We're one step further in porting nice features of PCVT over to wscons.
