To get CRC functionality in a client program, you now need to link with libpgcommon instead of libpgport. The CRC code has nothing to do with portability, so libpgcommon is a better home. (libpgcommon didn't exist when pg_crc.c was originally moved to src/port.) Remove the possibility to get CRC functionality by just #including pg_crc_tables.h. I'm not aware of any extensions that actually did that and couldn't simply link with libpgcommon. This also moves the pg_crc.h header file from src/include/utils to src/include/common, which will require changes to any external programs that currently does #include "utils/pg_crc.h". That seems acceptable, as include/common is clearly the right home for it now, and the change needed to any such programs is trivial.
