+ Some basic deadchip detection.

Browse Source 
+ Enable FIFO bursts, but also detect bogus 1040A with busted FIFO.
+ Use new MEMZERO crossplatform define.
+ Handle RQCS_QUEUE_FULL status case and let upper layer parse SCSI ststus
  byte if nonzero (should be 0x28- Queue Full status)
+ Fold ISP_NVRAM_FIFO_THRESHOLD_128 into isp_fifo_threshold tag.
