    * Add vnode0,vnode1 slots to the delays table. This will allow us to
      match ipfw pipes to nodes after swapin, hopefully allowing us to
      control the delays for lans in addition to duplex links.
    
    * Add IPaliases to interfaces table. Used in assign_wrapper when
      constructing "emulated" links, which will share a link via the use
      of aliases on the interface. This is a comma separated list of IP
      addresses (no, I refuse to make this a separate table!).
    
    * Add virtnode_capacity slot to node_types, defaults to zero. This is
      used in ptopgen for determining how many virtnodes fit on a real
      node. I have not thought this through completely, but it allows me
      to make progress on other fronts.
    
    * Add linkdelays delays, which sorta resembles the delays table, only
      this table stores oneway delays links, to be set up on the endpoints
      of a link or lan. Also, instead of being based on ipfw bridge rules,
      it is based on IP address/mask rules. At some point this table may
      merge witk the delays table, but will take time to work out the
      details and I do not want to mess up existing experiments by
      changing the delays table! Anyway, a duplex link gets one of these
      for each endpoint (a xmit ipfw rule). To mimic our lan setup, lan
      links get two, an xmit *and* a recv rule. My hope is that link
      delays will look just like normal delays (a packet leaving a node
      for a lan will get the outgoing delay, and a packet arriving gets
      the incoming delay).
