Add sigemptyset, sigfillset, sigaddset, sigdelset and sigismember with FreeBSD 11 semantics (lib/libc/gen/sigsetops.c): a 128-bit set of four 32-bit words, signal n at bit n - 1, signals 1 to 128 valid. sigfillset sets every bit. An invalid signal returns -1 with errno EINVAL and leaves the set untouched; sigismember returns 1 or 0. A null set throws. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
