model+helper+tests: Create an ndnSIM-specific transport for the NFD face system
This commit replaces the previous hack of implementing NS-3's inter-node
communication using the LinkService abstraction of the NFD face system.
The new implementation has higher memory overhead, but allows simulation
of any LinkService versions, including GenericLinkService that
implements NDNLPv2 protocol (i.e., fragmentation, network NACKs, etc.).
