I assume its still in WIP, but make sure the unit tests are not nulled out before merging :)

while testing against BIRD, we found out that if one doesn't explicitly request -protocol 2, then after BIRD sends Serial Query with verson set to 2, StayRTR replies with Cache Response but version set to 1

supposing that both sides are violating the draft here, section 7, because in this case, StayRTR should either accept version 2, or send Error Report with code 4, and BIRD should, after receiving a different version, probably drop the session as well
