    ikev2 nat: make floating the initiator's endpoints to :4500 explicit
    Extract a quirky interaction where ikev2_natd_lookup() (if
    NAT_T_DETECTED and initiator) calls nat_traversal_change_port_lookup()
    (MD==NULL) and only local interface is updated.  Move code to
    v2_nat_initiator_endpoints() and only calling when the initiator.
    pexpect .st_local{addr,port} == .st_interface's .local_endpoint.
    pexpect local port :54500 exists.
    (Better terminology needed: the RFC describes this as "MUST tunnel all
    future IKE and ESP packets [...] over UDP port 4500" - overloading
    "tunnel"; and older code describes this as "floating" - yet the port
    isn't "floating around" as it must be :4500)
