fib: FIB Entry tracking
Instead of all clients directly RR sourcing the entry they are tracking, use a deidcated 'tracker' object. This tracker object is a entry delegate and a child of the entry. The clients are then children of the tracker. The benefit of this aproach is that each time a new client tracks the entry it doesn't RR source it. When an entry is sourced all its children are updated. Thus, new clients tracking an entry is O(n^2). With the tracker as indirection, the entry is sourced only once.
