Message:

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.
