Amazon is going to use the reachable framework to fix some connection
bugs in the TCP BTL, so claim support ownership of the weighted and
netlink components.

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.

The mca_base_select function uses returned priorities to select the
best component/module. This priority may be of use to the caller so
pass that information back in an optional argument. If the priority is
not needed pass NULL.

This commit adds an owner file in each of the component directories
for each framework. This allows for a simple script to parse
the contents of the files and generate, among other things, tables
to be used on the project's wiki page. Currently there are two
"fields" in the file, an owner and a status. A tool to parse
the files and generate tables for the wiki page will be added
in a subsequent commit.
