Make improvements
- Let OpenMP be usable via cosmocc - Let libunwind be usable via cosmocc - Make X86_HAVE(AVXVNNI) work correctly - Avoid using MAP_GROWSDOWN on qemu-aarch64 - Introduce in6addr_any and in6addr_loopback - Have thread stacks use MAP_GROWSDOWN by default - Ask OpenMP to not use filesystem to manage threads - Make NI_MAXHOST and NI_MAXSERV available w/o _GNU_SOURCE
