Title: Review the new router design, especially the filter part

* No more generic classes
* extract creation of context in a dedicated feature (can be redefined)
* introduce new class WSF_FILTER_CONTEXT_HANDLER
* type of {WSF_FILTER_HANDLER}.next is WSF_FILTER_HANDLER and not WSF_HANDLER

The last point is important as it allows to have a filter chain of more than
2 filters (otherwise, it is stopped after the call of {WSF_HANDLER}.execute
