b2942b3c53 cluster: Support running multiple instances on the same host 
With IP_MULTICAST_LOOP they can see each other. We "just" have to make sure
they use different IP addresses and route metrics to distinguish from each
other.

e442a69fc1 cluster: try make the cluster socket high-priority 
The heartbeat messages, notably, should really not be lost, otherwise the
cluster will dismantle itself if some very-high trafic is filling packet
queues.

9daccab8ba shutdown_handler: really shutdown when we are last 
If we are a master and we don't have peers, there is no use keeping the
sessions alive, when we'll restart we will have forgotten them all.
Better gracefully close them, so they can be quickly respawn on restart,
instead of having to wait for timeouts.

845bb1f376 Apply MLPPP patch from Muhammad Tayseer Alquoatli, very belatedly, with 
thanks.  Changes:
- Handle session shutdown gracefully regarding leaving the bundle (bug that is
  caused when a all session leaves a bundle then another join)
- IP assignment is done only for the first session in the bundle (save IP
  waste for multiple MLPPP sessions)
- Route is being added only for the first session in the bundle (less routes
  on l2tpns system)
- Fix route deletion problem for MLPPP sessions (bug that caused when a
  session leaves a bundle)
- Uniformity of sequence number space satisfied (according to RFC1990)
- Fix reassembling fragmented packets and handling lost fragments (according
  to RFC 1990)
- FragmentatConnection to l2tpns.cvs.sourceforge.net closed by remote host.n
  across N session rather than two)
- Sequence numbers extraction mask has been corrected (bug in extracting
  sequence numbers)
- some clustering support fixes
- Upload/Download statistics has been corrected
- add "kill_timedout_sessions" config option
