> Add CRC32C as another DataChecksum implementation

> CRC32C is another checksum very similar to our existing CRC32, but with a
> different polynomial. The chief advantage of this other polynomial is that
> SSE4.2 includes hardware support for its calculation. HDFS-2080 is the
> umbrella JIRA which proposes using this new polynomial to save substantial
> amounts of CPU.
