------------------------------------------------
Okie. I will rework on that part now. I t hink it happened because I added this
class before the BBUtils and UnsafeAccess got committed. Let me remove the
unused APIs and repeated APIs from those classes.

> In L2 cache (offheap) an HFile block might have been cached into multiple
> chunks of buffers. If HFileBlock need single BB, we will end up in recreation
> of bigger BB and copying. Instead we can make HFileBlock to serve data from
> an array of BBs.
