functypes: provide the recv and send arg and return types
This header is for providing the argument types for recv() and send() when built to not use a dedicated config-[platfor].h file. Remove the slow brute-force checks from configure and cmake. This change also removes the use of the types for select, as they were not used in code. Closes #9592
