Give up on trying to mechanically forbid abort() within libpq. Even though there are no such calls in the source code, we've now seen three different scenarios where build toolchains silently insert such calls: gcc does it for profiling, some platforms implement assert() using it, and icc does so for no visible reason. Checking for accidental use of exit() seems considerably more important than checking for abort(), so we'll settle for doing that for now. Also, filter out __cxa_atexit() to avoid a false match. It seems that OpenBSD inserts a call to that despite the fact that libpq contains no C++ code. Discussion: https://postgr.es/m/3128896.1624742969@sss.pgh.pa.us
