 The DHCPv6 server code, which processes the Client FQDN option has to be
 refactored. Currently, the FQDN option is not appended to the server's
 response until the very end of message processing. At the end of message
 processing we check if option was requested or not. If it was, it is
 appended to the response.

 We think it is better to append the option to the response as soon as the
 option is generated. This will eliminate the need to pass the option in a
 separate variable all the way through different functions. This will
 simplify the code.
