From: Geliang Tang <[email protected]> This patch extracts a new helper client_socket() from connect_to_fd_opts() to create the client socket, but don't connect to the server. Then connect_to_fd_opts() can be implemented using client_socket() and connect_fd_to_addr(). This helper can be used in connect_to_addr() too, and make "noconnect" opts useless.
