4e0744954a Rewrite of important parts of the Collect logic: link estimation
calculation and parent selection.  This fixes a severe bug that caused
loops when packets were erroneously retransmitted due to ACK loss.

e000b1abf3 A major update to ContikiRPL resulting in a reduced code footprint by
300 bytes, as well as cleaner protocol logic.

* Made parent management uniform.

* Simplified the DIO processing.

* Improved the Objective Function API and its documentation.

* Removed redundant code at various places.

* Improved identifier naming.

* Switched visualization from candidate parents to preferred parents only.

* Made DAO ACK transmissions configurable.

* Improved initial ETX guess by using a cached local confidence value.

* Added a periodical rank recalculation function to reduce
  the maximum stack depth.

* Increased the Trickle redundancy constant to ensure faster
  topological updates.
