    Description

      This subtask deals with some improvments that can be done in the read path (scans) after the changes for HBASE-11425 went in.
      -> Avoid CellUtil.setSequenceId in hot path.
      -> Use BBUtils in the MultibyteBuff.
      -> Use ByteBuff.skip() API in HFileReader rather than MultiByteBuff.position().
