Add best route match support for path resolver

In path resolver, nexthop address was matched only against an exact (/32)
route match. This has been relaxed to instead do a best match, if longest
match is enabled.

o Since there can ne more one matching route for a given address, all
such matching routes are maintained inside an std::set.
o This set sorted based on the prefix length in descending order. This
ensures that best match is always at the Set:begin() position.
o This set access is protected using a mutex.
o Added couple of integ tests in path resolver as well as some unit tests
to verify routes add/delete inside the set.

This is specifically useful for mvpns, where in Source in <S,G> needs to be
resolved over the best unicast path available. By default, nexthop_longest_match
in PathResolver is disabled.
