handles are kernel objects since Windows 8. * fhandler.h (enum conn_state): Add "listener" state. (class fhandler_socket): Drop listener status flag. (fhandler_socket::lseek): Return -1 and errno ESPIPE. (fhandler_serial::lseek): Ditto. * fhandler_socket.cc (fhandler_socket::listen): Set connect_state to listener. Add comment. (fhandler_socket::accept4): Explicitely check if the socket is listening and fail with EINVAL, if not. Explain why we have to do that. (fhandler_socket::recv_internal): Explicitely check if the socket is connected if it's a stream socket. Explain why we have to do that. (fhandler_socket::getpeereid): Drop now redundant test.
