network: Rework address lookup to use only events

Browse Source 
In order to get the IP address of an interface, we can get the
information out of NEWADDR events without needed to call getifaddrs().
And when now events are expected, we can requests a dump of all
addresses and handle addresses changes the same way via handleEvents()
only.
