NLSR

Currently, the order of next hops with the same cost installed in NFD's FIB depend on the order that adjacencies are detected by NLSR. NLSR's routing table sorts ties using lexicographical ordering based on the next hop's FaceUri.

NLSR receives router B's adjacency LSA and determines it can reach router C through router B with cost 2
NLSR registers (Name: router C's prefix, next hop: router B, cost: 2)
NLSR receives router A's adjacency LSA and determines it can reach router C through router A with cost 2
NLSR registers (Name: router C's prefix, next hop: router A, cost: 2)

NLSR's ordering
(..., next hop: router A, ...), (..., next hop: router B, ...)

NFD's ordering
(..., next hop: router B, ...), (..., next hop: router A, ...)

This task should determine a way to keep these two view consistent with one another.
