Hello

The problem can be traced to hello-timers being repeatedly cancelled when an
AODV packet was received or sent. Thus when L7 traffic was sent, the RREQs and
RREPs resulted in the hello-timers barely getting triggered, which caused
severe loss in adjacency.

+1 to commit.  Please see my comments on bug 1194.

This will cause routing-aodv-regression traces to change but I have reviewed the changes and the correct AODV behavior is preserved.
