faff1c2a7e Preliminary support for RPL node types. This change allows a node to be in any of three given types: 
* Mesh: this is the normal case. Nodes route data on behalf of others and the node can be reached via a DAO route.
* Leaf: the node does not route data on behalf of others, but others can route data to the node (it has a RPL DAO route).
* Feather: this is a new type of node. A feather node routes data on behalf of others, but does not install DAO routes in the network. Feather nodes allow having a larger number of nodes than the RPL network can sustain in terms of routing tables.

This commit introduces the RPL node types and the feather mode, but does not add support for the leaf node type.

61ea7fbb1c RPL DAO timers and management: 
* Added a DAO lifetime timer that sends out a new DAO after half the lifetime of the DAO. This allows implementing DAO route soft state that avoids routing tables in the network keeping stale routes for ever.
* Added ways to schedule a new DAO transmission as well as cancelling an active DAO transmit timer, which makes it possible to do nodes that don't send DAOs.

c1c64dd1cc Received UDP packet was counted twice in statistics, first in udp_input and then again in udp_found. 
Fix this to use same logic as in uip.c: valid packet is counted only in udp_found.

c67c048cac Clean up setting channel and CCA-threshold for CC2420 based motes. 
The CCA-threshold now defaults to -46 which give better simulation
results and typically also better experimental results.
This adjustment is also needed due to commit 0a13f99 in mspsim. As
promised in https://github.com/mspsim/mspsim/pull/18 it broke the
regression tests.

43b5425493 Cleaned up various fragments and fixed a compilation error that occured when switching metric container. 
Fixed a wrapping problem in the ETX EWMA calculation.

Corrected the multiplier of the link metric, and simplified the configuration
so that the user does not need to specify the multiplier.
