bq.      HBASE-4322 [hbck] Update checkIntegrity/checkRegionChain to present more accurate
region split problem summary
bq.      
bq.      Minor semantics change
bq.      - if two regions overlap this counts as two inconsistencies instead of one. If three
overlap, it counts as three.
bq.      - testMetaHole was previously actually was an overlap ([D,E] overlaps [C,]).  Change
to make true hole.
bq.  
bq.  
bq.  This addresses bug HBASE-4322.
