Add a "scrollskip" member to wscons_emulfuncs (XXX even though it's not

a function) which specifies how many lines will be skipped when scrolling
up when the bottom of the screen is reached. Dumb framebuffers skip 10
lines (as before) because the copies are s ... l ... o ... w, but it's
silly to skip 10 lines on VGA, since the copies are much faster, so we
only skip one in that case.

In addition to MAS_ABT, check TAR_ABT when doing configuration space

reads. This is necessary because of newer AlphaStation firmware doing

Apparently, new AlphaStation 500/600 firmware has the same problem with
...
PCI master aborts as eb164 firmware, so use the same workaround mechanism
on all system types (clear error register's master abort bit, and check
it after accessing configuration space), not just eb164's.
This also fixes a bug on eb164's - when making the Alpha port compile
again, I made an error that caused this to not be used on eb164 systems,
either. Thanks to Matt Jacob for pointing out this goof.
