Application-side message processing.

Usage on the router side:

    nxt_app_wmsg_t       wmsg;
    nxt_app_parse_ctx_t  parse_ctx;

    nxt_app_http_req_init(task, &parse_ctx);

    /* parse incoming request data */
    if (nxt_app_http_req_parse(task, &parse_ctx, buf) == NXT_DONE) {

        /* choose app */
        nxt_app = nxt_select_app(... &parse_ctx.r ...);

        /* find port */
        wmsg.port = nxt_get_app_port(... nxt_app ...);
        wmsg.buf = &wmsg.write;

        /* fill write message buffer in shared mem */
        nxt_app->prepare_msg(task, &parse_ctx.r, &wmsg);

        /* send message to app for processing */
        nxt_port_socket_write(task, wmsg.port, NXT_PORT_MSG_DATA,
                              -1, 0, 0, wmsg.write);
    }
