    packets: use a substructure mechanism when checking IKEv2 last substructure field
    
    IKEv2 has nested substructures.  An SA Payload contains Proposal
    Substructures, and a Proposal Substructure contains Transform
    Substructures.
    
    When emitting the substructure, the Last Substruc[ture] field is set
    to either that substructure's type (non-last) or zero (last).
    
    This is separate to IKEv2's Next Payload field and the payload "chain"
    - the SA payload is both linked into the payload "chain" (.PT) and
    requires a specific sub-structure (.SST).
