The idea is that the way to measure the quality of a link is totally dependant 
on the plugin you activate... there will be a ETX plugin (which should 
produce the same routing we have now), but there could be other LQ plugins 
too (for example the ETT metric discussed here on the mailinglist).

This way we could change the routing metric without reprogramming the core of 
olsrd. Of course there should be a fallback (maybe simple RFC routing ?).
