Marco Baffo 5e4c9a69ea PUSH_UPDATE server: remove old IP(s) from vhash after sending a message containing ifconfig(-ipv6)
When sending a PUSH_UPDATE containing an ifconfig(-ipv6) option, we must add the new IP to the
multi_context vhash (hash table of the clients indexed by virtual IPs). Now in addition to
adding new client IPs, old IPs are also removed from vhash, allowing for a more complete update.
