The original placement of this module in src/fe_utils/ is ill-considered, because several src/common/ modules have dependencies on it, meaning that libpgcommon and libpgfeutils now have mutual dependencies. That makes it pointless to have distinct libraries at all. The intended design is that libpgcommon is lower-level than libpgfeutils, so only dependencies from the latter to the former are acceptable. We already have the precedent that fe_memutils and a couple of other modules in src/common/ are frontend-only, so it's not stretching anything out of whack to treat logging.c as a frontend-only module in src/common/. To the extent that such modules help provide a common frontend/backend environment for the rest of common/ to use, it's a reasonable design. (logging.c does not yet provide an ereport() emulation, but one can dream.) Hence, move these files over, and revert basically all of the build-system changes made by commit cc8d41511. There are no places that need to grow new dependencies on libpgcommon, further reinforcing the idea that this is the right solution.

# libpgcommon.a - contains object files with FRONTEND defined,

# libpgcommon_shlib.a - contains object files with FRONTEND defined,
