LOL, "global name-space minefield" -- that's funny.

Yeah, I didn't think the aic94xx_sas.h would be
used the way it is (or that the SAS Stack would become
a "pimple" as opposed to a layer as originally defined).

In macro name definitions, I tried to stay as close
as possible to the specs of the chip.

Anyway, I ack this patch. See below.

(Maybe scsi.h::ABORT_TASK should go away for the better
defined scsi.h::TMF_ABORT_TASK.)
