Currently, the various checksum types only provide the capability to calculate the checksum of a range of a byte array. For
HDFS-2080, it's advantageous to provide an API that, given a buffer with some number of "checksum chunks", can either calculate or verify the checksums of all of the chunks. For example, given a 4KB buffer and a 512-byte chunk size, it would calculate or verify 8 CRC32s in one call.
This allows efficient JNI-based checksum implementations since the cost of crossing the JNI boundary is amortized across many computations.
