 In the general case, the DHCPv6 server is operating on multiple
 interfaces. The failure to open a socket on one of them should not
 preclude other sockets to be open. The same problem for DHCPv4 had been
 reported and resolved as #2765. In #2765 the error handler function has
 been used to report an error without throwing an exception from
 openSockets6. This change will require a few unit tests so the #3251
 should be resolved first.
