CHECKSUM TABLE - optimize calling my_checksum with larger chunks

Details

    • 10.1.14

    Description

      Checksum implementations contain optimizations for calculating
      checksums of larger blocks of memory.

      This optimization calls my_checksum on a larger block of memory
      rather than calling on multiple adjacent memory as its going though
      the table columns for each table row.

      Note: I am planning to submit optimized crc32 code soon.

          serg, this patch looks alright, but I'd like you opinion too. I believe we should shift fix version from 10.1 to 10.2. Also pay attention to my comments in PR#165.
