Multiple efforts have been made gradually to improve the CRC performance in Hadoop. This JIRA
is to back port these changes to branch-1, which include HADOOP-6166, HADOOP-6148, HADOOP-7333.

The related HDFS and MAPREDUCE patches (e.g., HDFS-496 and MR-782) will be uploaded to their
original JIRAs.
