This feature was never used, is hardly documented and appears to be
designed to fiddle with the internal dispatch tree state.
Given that, simply drop the related code to simplify the dispatcher
class somewhat.

The lookup function takes multiple, possibly malformed path fragments,
splits them on slashes, constructs a temporary path and looks up the
result in the dispatch tree.
If a matching node has been found, the function will return both the
node reference and the canonical url to it.
If no corresponding node is found, the function returns nil.
