Ralph Castain d5dfe05521 Remove stale code associated with OPAL_THREADS_HAVE_DIFFERENT_PIDS. In the past, we have supported the case of really, really old Linux kernels where threads have different pids. However, when we updated the event library, we didn't also update that support code. In addition, when we dropped progress thread support, we didn't remove areas of the code that could no longer be compiled (i.e., were protected by "if progress thread && if have different pids).
There was no compelling reason to support such old kernels. Accordingly, convert the test to print a nice error message indicating we no longer support old kernels (but indicate that earlier OMPI versions do) and error out. Remove all code that was protected by "if have different pids" since it can no longer be compiled.
