Add user-callable CRC functions.
We've had code for CRC-32 and CRC-32C for some time (for WAL
records, etc.), but there was no way for users to call it, despite
apparent popular demand. The new crc32() and crc32c() functions
accept bytea input and return bigint (to avoid returning negative
values).
Bumps catversion.
