    network - Completely revamp the netisr / dispatch code
    
    * All netisrs are dispatched MPSAFE (followup in later commits)
    
    * Centralize the protocol threads.  There is now just one thread
      per cpu managed by the netisr code.  No more separate tcp/udp threads
      on each cpu.
    
    * Make the mbuf M_HASH/m_pkthdr.hash mechanic the central routing
      mechanic for netmsgs.
    
    * Remove the netisr ip_mport and pktinfo_portfn stuff and replace with a
      cpufn function which handles M_HASH/m_pkthdr.hash when M_HASH is not
      already set.
    
    * Seriously clean up the packet input paths.  Adjust ether_input_chain() and
      friends to not have to adjust the mbuf forwards and backwards, instead
      pass a header offset to the ni_cpufn function.  The ip pullup and other
      related code will use the offset to determine where the ip header is
      within the packet.
