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.

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

Check if the nexthop neighbor for a given route has disappeared. If so, we drop the route too. If we happen to be the RPL root, we also initiate a global repair as the neighbor may moved.

6lowpan fragmentation bugfix: the 6lowpan code had an unfortunate
...
interaction with the behavior of the rdc layer. If the first packet of a
fragment transmission was lost, the remaining packets would get dropped
on reception. Moreover, the reception code contained a bug that
sometimes would cause fragments to be misidentified as fragments. Taken
together, these problems would result in a pathelogical network
breakdown if too many fragmented packets would occur simultaneously.
