------------------------------------------------

bq. Let it be a BB backed one.
Yes.  That is why in the attached patch for ease of use created buffer for even the fake keys
that we create that includes KeyOnlyKV. In the read path both should be BB based only.

> 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.
