20a7933f53 After thinking again, implement cam_ccbq_fini().
This is effectively NULL change, but makes this API a bit more consistent.

362abc449c - Providing fine-grained malloc statistic by replacing M_DEVBUF with
module-specific malloc types.  These should help us to pinpoint the
  possible memory leakage in the future.
- Implementing xpt_alloc_ccb_nowait() and replacing all malloc/free based
  CCB memory management with xpt_alloc_ccb[_nowait]/xpt_free_ccb.  Hopefully
  this would be helpful if someday we move the CCB allocator to use UMA
  instead of malloc().

5a526431f8 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.

8bad620d54 Remove camq_regen(). We already perform modular comparisons
for generation counts, so no further steps to deal with generation
count wrap are required.

Fix an off by one problem in the camq heap code.
