Excessive filtering in RegionScannerImpl
I may be be do not understand fully the overall design of a scanner system
in HBase but it looks like we do double filtering on KVs during scan
operation. First time in StoreScanner.next (see ScanQueryMatcher.match) and
second time in RegionScannerImpl.nextInternal.
