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.
