> This adds full support for local/remote Sequence Window feature, from which the

> 
> Specifically, the following is contained in this patch:
>   * integrated new socket fields into dccp_sk;
>   * updated the update_gsr/gss routines with regard to these fields;
>   * updated handler code: the Sequence Window feature is located at the TX side,
>     so the local feature is meant if the handler-rx flag is false;
>   * the initialisation of `rcv_wnd' in reqsk is removed, since
>     - rcv_wnd is not used by the code anywhere;
>     - sequence number checks are not done in the LISTEN state (cf. 7.5.3);
>     - dccp_check_req checks the Ack number validity more rigorously;
>   * the `struct dccp_minisock' became empty and is now removed.
