To simplify implementation of mirror-to-gretap tests, extend lib.sh with several new functions that might potentially be useful more broadly (although right now the mirroring tests will be the only client). Also add mirror_lib.sh with code useful for mirroring tests, mirror_gre_lib.sh with code specifically useful for mirror-to-gretap tests, and mirror_gre_topo.sh that primes a given test with a good baseline topology that the test can then tweak to its liking.
