For the generalisations to forwarding we want to accomplish with the
flow table, we will need a more formalised notion of passt
"interfaces" - that is way that passt communicates with network,
whether that be over L4 sockets (as on the host) or via an L2 tunnel.

This series makes a small start on this, by introducing a type to
identify passt interfaces.  We don't use it for a whole lot yet, but
it will become more useful in future.

Based on the automatic port forwarding cleanup series

Changes since v1:
 * Don't use a type alias for pif ids, just use bare uint8_t

David Gibson (4):
  udp: Clean up ref initialisation in udp_sock_init()
  pif: Introduce notion of passt/pasta interface
  pif: Record originating pif in listening socket refs
  pif: Pass originating pif to tap handler functions
