Added processing of client transport parameters. note: + parameters are available in SSL connection since they are obtained by ssl stack quote: During connection establishment, both endpoints make authenticated declarations of their transport parameters. These declarations are made unilaterally by each endpoint. and really, we send our parameters before we read client's. no handling of incoming parameters is made by this patch.
