cam_periph.c:
Move handling of CAM_AUTOSENSE_FAIL into block dealing with
all other scsi status errors.
cam_queue.c:
cam_queue.h:
Fix 'off by one' heap bug in a more efficient manner. Since
heap algorithms like to deal with indexes started from 1,
offset our heap array pointer at allocation time to make this
so for a C environment. This makes the implementation of the
algorithm a bit more efficient.
cam_xpt.c:
Use macros for accessing the head of the heap so that code
is isolated from implementation details of the heap.
