  Log:
  Get rid of UMA zones and instead allocate all ecb's up front and track them
  in a TAILQ.  Re-arrange some of the ecb elements so that they can stay
  stable through alloc/free cycles while the rest get bzero'd.
  
  - Use the tag_id from the ecb rather than fro the ccb.  The latter is only
  for target mode.
  
  - Honor the ccb flags for tag_action when deciding whether to do a tagged
  or untagged transaction.
  
  - Re-arrange autosense completion so that it works correctly in failure
  cases.
  
  - Turn on the PI_TAG_ABLE flag so that CAM will send us tagged transactions.
  
  This enables tagged queueing in the driver.
