zlib's implementation uses CRC-32-IEEE 802.3 polynomial (0xedb88320) but with starting value 0xffffffff, so introduce another crc32 implementation - CRC32IEEE that has starting value - 0 Also add CRC64 with ECMA polynomial. v2: s/crc*_data./crc*_data./ to avoid conflicts with other crc32.h in contrib v3: join with existing CRC32()
