[Click] Click router: routertask

[Eddie Kohler]

Hi Andrushka,

Strip has no Task.  That configuration has exactly one element with a 
Task, namely InfiniteSource.  Tasks are stored on a doubly-linked list 
where the routertask is the sentinel indicating end of list.

The connections between elements, such as InfiniteSource -> Strip, are 
stored in the Element::_ports array, accessible by 
Element::input()/Element::output()/etc.
