bde 91a5e56364 Don't allow negative console numbers for the VT_WAITACTIVE ioctl. Use the
correct console number for the VT_WAITACTIVE ioctl.  Invalid console numbers
caused waiting on an invalid pointer.

Use bcopyw() instead of move_up() and move_down().  bcopyw() handles
overlapped copies and should be faster.  Actually use bcopy().  bcopy()
is slightly faster if video memory is 16-bit and about twice as fast if
it is 32-bit.  bcopy() is said to fail on someGA's, but syscons already
depends on it working for other accesses to video memory.
