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.

This commit adds support for project_framework_component_* parameter
matching. This is the first step in allowing the same framework name
in multiple projects. This change also bumps the MCA component version
to 2.1.0.
All master frameworks have been updated to use the new component
versioning macro. An mca.h has been added to each project to add a
project specific versioning macro of the form
PROJECT_MCA_VERSION_2_1_0.
