Makes it much easier to see what thing complained. Getting thread id, program name and thread name vary wildly between Linux and FreeBSD, so those are set up in macros. pthread_getname_np() did not appear in musl until very recently, but the same info has always been available via prctl(PR_GET_NAME), so we use that instead.
