Log Message:
BUFQ_PRIOCSCAN:

- to reduce cpu consumption for a long queue, maintain the sorted lists of
  buffers with rbtree instead of TAILQ.  i vaguely remember that the problem
  pointed out by someone on a public mailing list while ago.  sorry, i can't
  remember who and where.

- add some #ifdef'ed out experimental code.

- bump kernel version for struct buf change.
