If the epoch that we see during a Probe is less than the existing epoch,
it means that the gateway has either restarted or reset its

createOrGetMapping will not attempt to re-use it.

and we now use the standard SPDX-License-Identifier header.
This commit was done almost entirely mechanically with perl, and then

PCP handles external IPs by allowing the client to specify them in the packet, which is more
explicit than requiring 2 packets from PMP, so allow for future changes to add it in easily.
