non 292085c2c1 o Support AUTO SENSE correctly.
o Offset and period in synch messages and width negotiation should be
  done for per target not per lun. Move these from *lun_info to
  *targ_info.
o Change in handling XPT_RESET_DEV and XPT_GET_TRAN_SETTINGS .
o Change CAM_* xpt_done return values.
o Busy loop did not timeout. Change this to timeout as original NetBSD/pc98.
