Fixed a few major bugs. add_nubus_intr() was getting the wrong address, 

and bcopy and bzero were being used.  The latter use longs to copy/zero,
and some ethernet cards can't handle longs.  I've added bbcopy and bbzero
as a temporary hack, but these should later be added to locore and maybe
changed to use shorts.  Still doesn't work: I can now get an interrupt on
the first transmit, but further transmits don't generate more interrupts.
