- If caller specifies readbehind and readahead that together with count
  doesn't fit into a buf, then trim readbehind and readahead evenly.  If
  rbehind was limited by the previous BMAP, then roundup its trim to
  block size.
- Add KASSERT to check that b_blkno has proper offset from original
  blkno returned by BMAP. [1]
- Add KASSERT to check that pages in buf are consecutive.
