On Darwin, detect and report a multithreaded postmaster. Darwin --enable-nls builds use a substitute setlocale() that may start a thread. Buildfarm member orangutan experienced BackendList corruption on account of different postmaster threads executing signal handlers simultaneously. Furthermore, a multithreaded postmaster risks undefined behavior from sigprocmask() and fork(). Emit LOG messages about the problem and its workaround. Back-patch to 9.0 (all supported versions).
