> The default checksum algorithm of Hadoop is CRC32C, so we'd better add a new test to
compare Crc32C chunked verification implementations.
> This test is based on Crc32PerformanceTest, what I have done in this test is:
> 1.CRC32C performance test.
> 2.CRC32C is not supported by java.util.zip in JAVA JDK, so just remove it from this test.
> 3.User can choose either direct buffer or non-directly buffer to run this test manually.
> 4.Take use of verifyChunkedSumsByteArray for native to support non-directly native test.
