Add a build-time check that libpq doesn't call exit() or abort(). Directly exiting or aborting seems like poor form for a general-purpose library. Now that libpq liberally uses bits out of src/common/, it's very easy to accidentally include code that would do something unwanted like calling exit(1) after OOM --- see for example 8ec00dc5c. Hence, add a simple cross-check that no such calls have made it into libpq.so.
The cross-check depends on nm(1) being available and being able to work on a shared library, which probably isn't true everywhere. But we can just make the test silently do nothing if nm fails. As long as the check is effective on common platforms, that should be good enough. (By the same logic, I've not worried about providing an equivalent test in MSVC builds.)
