Add support for the Google xxhash checksumming function
It's a lot faster than the other software defined ones, so will
be a useful alternative for the cases where crc32c-intel isn't
available.

Store appropriate checksum in the header of each block. crc32c-intel is
hardware accelerated SSE4.2 driven, falls back to regular crc32c if
not supported by the system.
