HRegion.mutateRowsWithLocks() and HRegion.processRow()".
Here's the stack trace of failure. I don't think it is because of this patch.

> mutateRowsWithLocks() does atomic mutations on multiple rows.
> processRow() does atomic read-modify-writes on a single row.
> It will be useful to generalize both and have a
> processRowsWithLocks() that does atomic read-modify-writes on multiple rows.
> This also helps reduce some redundancy in the codes.
