visible screen memory. This results in a considerable performance win
at all depths.
- Correct clear_screen() behavior when clearing to the top and bottom of
screen; start at current cursor position, not current cursor row.
- Add local prototypes, and other KNF.
Also change the device probing scheme to use something a bit more rational.
A current side-effect is that nubus cards are double-mapped. I expect
to fix that shortly.
Also change splclock() to block everything but serial hardware interrupts.
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
