The interface destructor called pure virtual methods at least when cancelling ARP- waiting states. The implementations were made by the deriving classes Session_component respectively Uplink. This led to an abort of the NIC router as the destruction of the derived class was already done. A similar problem already occured in the past during the construction of Interface and was back then solved by introducing a separate init() method. This commit, however, solved the problem by making Interface a member of the other classes. Therefore, the init() method could be removed again. Furthermore, the interface polica could be moved from Session_component_base to Session_component. The commit also had to generalize the way the link state of an interface is determined. Fixes #2856
