Improve system calls
- Wrap clock_getres() - Wrap sched_setscheduler() - Make sleep() api conformant - Polyfill sleep() using select() - Improve clock_gettime() polyfill - Make nanosleep() POSIX conformant - Slightly improve some DNS functions - Further strengthen pledge() sandboxing - Improve rounding of timeval / timespec - Allow layering of pledge() calls on Linux - Polyfill sched_yield() using select() on XNU - Delete more system constants we probably don't need
