This addr manager should seriously help with the addrsplosion
problem.

Network now signals when it successfully listens on some address
or when an address shuts down. This will be used to establish and
close nat port mappings. It could also be used to notify peers
of address changes.

network interface now allows setting Listeners after the fact.
This is useful to create the network and start listening as
separate steps. And to keep the network up to date on new
addresses the node might have to listen to.

The net package is the next to move. It will be massaged
a bit still to fix the Network / "NetworkBackend" conflict.
