VPP-19: Split the lookup.h IP_LOOKUP_NEXT enum.
IP4 and IP6 nodes currently shares the adj->lookup_next_index. That has some issues, e.g. that one has to add non-functional nodes like ip4-hop-by-hop and that anyone dynamically adding nodes to any of the IP4/IP6 lookup nodes must ensure they add themselves to all relevant nodes to ensure next index consistency. This patch splits the IP_LOOKUP_NEXT into separate enums for IP4 and IP6 with a common part for next-nodes used by both. It sets up other IP nodes as siblings to avoid inconsistencies. This allows IP4 and IP6 lookup next nodes to evolve independently. The adj->lookup_next_index is still shared, assuming that an IP4 adjacency isn't used by an IP6 graph node.
