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.
