Make signal handling work well across platforms
- Fix sigsuspend() on XNU - Fix strsignal() on non-Linux - Add unit tests for strsignal() - Add unit tests for setitimer() - Add unit tests for sigsuspend() - Rewrite setitimer() for New Technology - Rewrite nanosleep() for New Technology - Polyfill SIGALRM on the New Technology - select(0,0,0,0) on NT now calls pause() - Remove some NTDLL calls that aren't needed - Polyfill SA_NOCLDWAIT on the New Technology - Polyfill SA_RESETHAND on the New Technology - Polyfill sigprocmask() on the New Technology - Polyfill SIGCHLD+SIG_IGN on the New Technology - Polyfill SA_RESTART masking on the New Technology - Deliver console signals from main thread on New Technology - Document SA_RESTART behavior w/ @sarestartable / @norestart - System call trace in MODE=dbg now prints inherited FDs and signal mask
