* Add support for RES_USE_DNSSECjca2017-02-271-4/+5
| | | | | | | | | | | | RES_USE_DNSSEC is implemented by setting the DNSSEC DO bit in outgoing queries. The resolver is then supposed to set the AD bit in the reply if it managed to validate the answer through DNSSEC. Useful when the application doesn't implement validation internally. This scheme assumes that the validating resolver is trusted and that the communication channel between the validating resolver and and the client is secure. ok eric@ gilles@
