Add method to get the first neighbour which is about to expire
Code style fixes
Bugfix: Corrected wireshark bad FCS errors in COOJA Pcap export
Use no metric container when having MRHOF with ETX, as specified in RFC6719. Renamed rpl-of-etx to rpl-mrhof.
Makefile.include: add verbosity control (make V=1 for previous behaviour)

This shortens $(CC) and $(AR) lines to a much more readable length,
making warnings stick out clearly.

The spaces after "CC" and "AR" are to reserve space for other operations
that may use longer names, such as the communly found "BUILD" or
"GENERATE".
