> RegionObserver.preStoreScannerOpen() doesn't have acces to current readpoint. This is
crucial e.g. when creating a new StoreScanner.
> Although it is possible to obtain the readpoint via following workaround:
> ((HStore)store).getHRegion().getReadpoint(IsolationLevel.READ_COMMITTED)
> ...it presumes some knowledge of HBase internals and is not a clear option for user.
> The problem was introduced in HBASE-9754, where readpoint was introduced as an argument
to StoreScanner constructor, but wasn't passed to the preStoreScannerOpen() hook in HStore.getScanner().
> In our case it led to bug, when we were incorrectly using smallestReadpoint() instead,
which made coprocessor missing data in some cases [1].
