Description

In our rpc specification, https://docs.google.com/document/d/1-1RJMLXzYldmHgKP7M7ynK6euRpucD03fZ603DlZfGI/edit#, we talk of passing lots of Cells outside of protobuf. We do it using Cell blocks. There are blobs filled with Cells that are encoded variously and optionally compressed.

This issue is about adding to hbase-common basic facility for building Cell blocks. It includes a codec Interface for encoding/decoding Cell blocks as well as a means of iterating an objects Cell content (prefix-tree's CellScanner).

This is a subtask of HBASE-7898 Serializing Cells over RPC
