Review request for hbase.


Changes
-------

refactored HRegion::forceSplit() api


Summary
-------

Add the ability to explicitly split an existing region at a user-specified 
point. Currently, you can disable automated splitting and can presplit a 
newly-created table at explicit boundaries, but cannot explicitly bound a split 
of an existing region.


This addresses bug HBASE-3328.
