Description
Provide a minimal PIT token implementation for interoperability with a downstream node that requires PIT tokens.
This issue includes:
- Encode and decode PIT token elements in NDNLPv2 header, as defined in #4432.
- Store downstream's PIT token in PIT in-record.
- Return the same PIT token to downstream when responding to an Interest with Data or Nack.
Under this issue, NFD itself does not use PIT tokens for table indexing or forwarding decisions.
