inclusions in src/include/catalog/*.h files. The main idea here is to push function declarations for src/backend/catalog/*.c files into separate headers, rather than sticking them into the corresponding catalog definition file as has been done in the past. This commit only carries out that idea fully for pg_proc, pg_type and pg_conversion, but that's enough for the moment --- if pg_list.h ever becomes unsafe for frontend code to include, we'll need to work a bit more.
