TL;DR: Pass scoped_refptr<> by value, and std::move()

Yea, this does go against the style guide. But following that will lead to
unnecessary reference cycling, since not all the implementations actually need a
reference, and the caller can't move() its own reference.

       const TrustAnchorsCallback& callback,
       TrustAnchors* synchronous_matches,
       std::unique_ptr<Request>* out_req) const = 0;
 
  private:
   DISALLOW_COPY_AND_ASSIGN(TrustStore);
