Fix a bug in IPv4 address configuration exposed by refcounting.
* Join the IPv4 all-hosts multicast group 220.127.116.11 once only;
that is, when an IPv4 address is first configured on an interface.
* Do not join it for subsequent IPv4 addresses as this violates IGMP.
* Be sure to leave the group when all IPv4 addresses have been removed
from the interface.
* Add two DIAGNOSTIC printfs related to the issue.
Further care and attention is needed in this area; it is suggested that
netinet's attachment to the ifnet structure be compartmentalized and
