[HICN-590] Removed andjacency type specific face implementation
Changes in the new implementation are: - the adjacency index is replaced with a dpo that allows the single face node to dispatch the packet to the right vlib node. - local and remote address in the face are replaced with a single nat address which is used to perform the nat operation when rewriting an interest or a data (in case of tunnels the nat address will be equal to 0) - the list of next hop in the load balance is no longer a list of dpos but a list of face id (this makes the code easier and increases the number of next hop we supports) Signed-off-by: Alberto Compagno <acompagn+fdio@cisco.com> Change-Id: I4ac2b4eb09425bfe1b3ca9f82d7d0ff564297b0d
