------------------------------------------------
Another thing is if that is the case then all the new APIs that we add in
ByteBufferUtils could just handle only the DBB cases (including the Unsafe
cases for DBB). Not the cases of normal BB because in this case we could still
work with byte[] inside the BB.
> Ensure Cells and its implementations work with Buffers also

> This issue can be used to brainstorm and then do the necessary changes for
> the offheap work. All impl of cells deal with byte[] but when we change the
> Hfileblocks/Readers to work purely with Buffers then the byte[] usage would
> mean that always the data is copied to the onheap. Cell may need some
> interface change to implement this.
