Paul Jones 8abdeabddc Make crc64 go faster 
The current crc64 algorithm is a variant of the Redis implementation.
Change it to a variant of the Adler implementation as described
at https://matt.sh/redis-crcspeed

Test program at https://github.com/PeeJay/crc64-compare
Filesize: 1.1G
Asking crc64-redis to sum "/media/peejay/BTRFS/1/ubuntu-14.04.5-desktop-amd64.iso"...
Asking crc64-adler to sum "/media/peejay/BTRFS/1/ubuntu-14.04.5-desktop-amd64.iso"...
Redis CRC-64: f971f9ac6c8ba458
Adler CRC-64: f971f9ac6c8ba458
Adler throughput: 1659.913308 MB/s
Redis throughput: 437.284661 MB/s
Adler is 3.79x faster than Redis
