When we can't find the default route, advertise all addresses so we have something.

Why does this generally occur? If it's a user configuration or router error is it worth logging it?

This can happen due to OS restrictions, or if the there are no network devices. We could probably just detect this case at the top and bail entirely.

I've changed this logic to only use fallback addresses if InterfaceMultiaddrs fails. If it just returns no addresses, we now accept that we have no addresses.

* If we fail to lookup interface addresses, do our best and bail. * Only fallback on guessing addresses if we fail to lookup any interface addresses. If the interface address lookup function returns nothing, accept that we have no IP addresses and move on. * Log when the NAT returns a bad address.

This patch fixes several address advertisements bugs that slipped through into go-ipfs 0.6.0.
We really need tests for this code, but that will likely require some mocking.
