Note: 3.2Patches version was built from scsidrivers-10.

changes from scsidrivers-10 to scsidrivers-13
   -- eliminated global variables aha_mb_area, aha_ccb[], aha_ccb_next,
      aha_board_id, ccbLock, numFreeCcbs; made them instance vars to 
      allow for multiple host adapters.
   -- Mailboxes and ccbs now dynamically allocated via IOMallocLow().
   -- Added 3.3 CDB length parsing
   -- Set mb->mb_stat = AHA_MB_IN_FREE *after* getting ccb ptr in 
      interruptOccurred
   -- Avoided re-init'ing ccb->waitLock in allocCcb
   -- deleted unused enqueue_tail(), dequeue_head() from AHAInline.h

      for 3.2
