Based on work from usNIC, the best way to use the reachability information the reachable components return is to build a connectivity graph between the two peers and run a bipartite graph solver. Rather than returning the "best" pairing, the reachability framework now returns the entire mapping, allowing a (soon to be added) graph solver to build the "optimal" connectivity pairing. Practically, this means changing the return type of the reachable() function and rewriting the weighted_reachable() function to return the full mapping. The netlink_reachable() function still always returns NULL. At the same time, fix bit-rot in the weighted component and enable builds of the component by removing the opal_ignore. Also, add IPv6 support to the weighted component to support both use cases in the TCP BTL. Signed-off-by: Brian Barrett <bbarrett@amazon.com>
