moves methods from Config to Conn receives

Pārlūkot izejas kodu 
generateKeyShare has nothing to do with Config receiver. It doesn't
configure anything. It has everything with connection so moved to Conn.
Making deriveECDHESecret also a method of Conn will make it possible to
access 'isClient' field.
