During debugging, I noticed that when an NCU is configured to use a static IP
address, and that address is applied, we see an RTM_NEWADDR followed by an
RTM_DELADDR of the same address. I had thought that this was down to us setting
the address prior to the netmask/prefixlen (we do things in the opposite order
in ifconfig), but I'm not sure. Merits further investigation, but for now, when
we handle IF_STATE events, we ensure that the RTM_DELADDR'ed address is really
gone. This prevents us from assuming the address has disappeared and
reconfiguring.
This behaviour does not occur for dhcpagent-applied addresses, so I suspect
it's down to either nwamd or libinetcfg.
