resolv: Implement trust-ad option for /etc/resolv.conf [BZ #20358]
This introduces a concept of trusted name servers, for which the AD bit is passed through to applications. For untrusted name servers (the default), the AD bit in responses are cleared, to provide a safe default. This approach is very similar to the one suggested by Pavel Šimerda in <https://bugzilla.redhat.com/show_bug.cgi?id=1164339#c15>. The DNS test framework in support/ is enhanced with support for setting the AD bit in responses. Tested on x86_64-linux-gnu. Change-Id: Ibfe0f7c73ea221c35979842c5c3b6ed486495ccc
