With Flower (CloudABI's network connection daemon) becoming more complete, there is no longer any need for creating any unconnected sockets. Socket pairs in combination with file descriptor passing is all that is necessary, as that is what is used by Flower to pass network connections from the public internet to listening processes. Remove all of the kernel bits that were used to implement socket(), listen(), bindat() and connectat(). In principle, accept() and SO_ACCEPTCONN may also be removed, but there are still some consumers left. Obtained from: https://github.com/NuxiNL/cloudabi MFC after: 1 month
