Review request for hbase.


Repository: hbase-git


Description
-------

This is a step toward final compacting memstore that allowes two modes of work: index-compaction
and data-compaction. 

The index-compaction means that when the new segment is pushed into the pipeline, it is flattened
and probably merged with old segments in the pipeline. The new merge "feature" induces no
data-copy-compaction and no speculative SQM scan. 
The compacting memstore of the data-compaction type means the usage of the data-copy-compaction.
