> Trying to remove API that returns the 'key' of a KV serialized into a byte
> array is thorny.
> I tried to move over the first and last key serializations and the hfile
> index entries to be cell but patch was turning massive. Here is a smaller
> patch that just redoes the optimization that tries to find 'short' midpoints
> between last key of last block and first key of next block so it is
> Cell-based rather than byte array based (presuming Keys serialized in a
> certain way). Adds unit tests which we didn't have before.
> Also remove CellKey. Not needed... at least not yet. Its just utility for
> toString.
