MikeBishop requested changes on this pull request.

As noted in #2413, this PR permits something that's currently prohibited intentionally -- migrating with a zero-length CID. Do we have consensus to make that change?

If there's no CID and the packet is coming from an unknown remote address, how does the server know what keys to use to remove packet protection in that case?  We've previously said we need to avoid trial decryption, and that seems like the only option if migration is permitted.
