Review request for hbase.
Changes
-------
I was porting this from my 0.89 diff. In 0.90, we can just directly add an
HRegionInterface RPC and not worry about incrementing the HRegionInfo VERSION.
Much cleaner and allows for rolling upgrades / mixed version environments.
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.

Note: this was primarily cluster-tested with 0.89 master.
Thanks,
