Following on @janaiyengar&#39;s insight that disable_active_migration is a property of an address, not a peer, we simply need to say which address the TP applies to.

This PR fixes #3608 by scoping the definition of disable_active_migration to the handshake address only.  This means that existing clients remain fully compliant, albeit slightly more conservative than necessary.

While I find @kazuho&#39;s argument convincing that a server capable of using SPA is highly unlikely to be unable to handle migration, it would be trivial for a future extension to define a second transport parameter carrying two bits that disable active migration for those addresses as well.
