This is a first draft of the first part of implementing a more general
flow table (connection tracking) as described at:
    https://pad.passt.top/p/NewForwardingModel

This is by no means complete.  So far it doesn't really do anything
new, it just reorganizes the TCP connection table to be closer to the
more general flow table.

Still it's ready for preliminary review.

David Gibson (8):
  tap: Don't clobber source address in tap6_handler()
  tap: Pass source address to protocol handler functions
  tcp: More precise terms for addresses and ports
  tcp, udp: Don't include destination address in partially precomputed
    csums
  tcp, udp: Don't pre-fill IPv4 destination address in headers
  tcp: Track guest-side correspondent address
  tcp, flow: Introduce struct demiflow
  tcp, flow: Perform TCP hash calculations based on demiflow structure
