Fine tune server candidate selection logic
DHCPv6 server info from ADVERTISE messages is inserted in the server
candidate list sorted according to the preference value (highest values
first in the list).
Server candidate list can only contain one entry from a given server.
Server with highest preference value is selected; in case the server
does not respond the next server is selected from the list.
When the server candidate list is empty and no servers responded;
the client restarts the DHCPv6 server discovery process

odhpc6c: status code support in reply
The patch implements support for status code handling in
reply messages as described in RFC3313 paragraph 18.1.8.
The client will
*log the status codes returned by the client
*send a request if no binding status code is returned for
a given IA
*send further renew/rebind if the IA was not present in
the reply
*terminate message exchange when no prefix/no address
status code is returned in reponse to a request
*terminate message exchange when unspec fail status code
is returned
*calculate t1/t2/t3 when all IA's have been processed and
based on recorded t1/t2/valid timer values per IA
Without this patch I have seen issues with request messages
send without any IA_PD/IA_NA and t1/t2/t3 timer values which
were not correct. These changes have been tested intensive
against an ISC DHCPv6 server
