        * src/ttt-server.h:
        * src/ttt-server.c: (ttt_server_init), (ttt_server_add_client),
        (_accept_client), (main): Add a new ttt_server_t object with a
        mutex-protected list of clients. Move client handling code down
        into new ttt-client.c.

        * src/ttt-client.h:
        * src/ttt-client.c: (ttt_client_create), (ttt_client_destroy),
        (ttt_client_handle_requests): New ttt_client_t object that simply
        holds a pointer back to the server as well as the client socket
        file descriptor.

        * src/ttt-socket.h:
        * src/ttt-socket.c: (ttt_socket_accept): Add closure argument. Add
        a call to fork before calling the accept callback.

        * src/ttt-args.c: Hide unused ttt_args_usage from the compiler to
        keep it from complaining.

        * src/ttt.c: (main): Rename the client main program from
        ttt-client to ttt.c, (since the server code now has its own
        ttt-client.c).

        * src/ttt.h:
        * src/Makefile.am: Include and link with pthread now that we have
        pthread-based mutex locking.
