Reintegrate branch: 20130111-hock-message_classes

improvements:

  • new message classes (reboost, zero-copy)
  • "fast path" for direct links (skip overlay layer)
  • link-properties accessible from the application
  • SystemQueue? can call boost::bind functions
  • protlib compatibility removed (32bit overhead saved in every message)
  • addressing2
  • AddressDiscovery? discoveres only addresses on which we're actually listening
  • ariba serialization usage reduced (sill used in OverlayMsg?)
  • Node::connect, easier and cleaner interface to start-up ariba from the application
  • ariba configs via JSON, XML, etc (boost::property_tree)
  • keep-alive overhead greatly reduced
  • (relayed) overlay links can actually be closed now
  • lost messages are detected in most cases
  • notification to the application when link is transformed into direct-link
  • overlay routing: send message to second best hop if it would be dropped otherwise
  • SequenceNumbers? (only mechanisms, so for: upward compatibility)
  • various small fixes


regressions:

  • bluetooth is not yet working again
  • bootstrap modules deactivated
  • liblog4xx is not working (use cout-logging)

This patch brings great performance and stability improvements at cost of backward compatibility.
Also bluetooth and the bootstrap modules have not been ported to the new interfaces, yet.
