* Add qemu-dm-sipb written by andersk to get us the domain ID in qemu-ifup

  * Add vif-sipbroute, a version of vif-route that does better netwwork
    isolation and has initial but useless ipv6 support.  This version also
    uses arpspoof to take over an address for domain migrations.
  * Add init script to enable rp_filter, proxy_arp and forwarding for the network config.
