Matthijs Mekking 667d81b52b Make serve-stale refresh behave as prefetch 
A serve-stale refresh is similar to a prefetch, the only difference
is when it triggers. Where a prefetch is done when an RRset is about
to expire, a serve-stale refresh is done when the RRset is already
stale.

This means that the check for the stale-refresh window needs to
move into query_stale_refresh(). We need to clear the
DNS_DBFIND_STALEENABLED option at the same places as where we clear
DNS_DBFIND_STALETIMEOUT.

Now that serve-stale refresh acts the same as prefetch, there is no
worry that the same rdataset is added to the message twice. This makes
some code obsolete, specifically where we need to clear rdatasets from
the message.
