Description (last modified by jinmei)

See #2056 for background. This is another one of such things,
referring to trac1607exp branch:

    // Called for DNAME case.  (Somehow) construct the synthesized CNAME
    // for the qname with the DNAME.  Return Rcode of NOERROR() normally,
    // but YXDOMAIN() if CNAME cannot be constructed because the name would
    // be too long.
    //
    // Default version: extract the DNAME RDATA, construct the synthesized
    //   cname by splitting and concatinating labels, create a new standard
    //   CNAME RRset and sets its (only) RDATA to the created cname.
    // Optimized in-memory version: construct the synthesized cname
    //   essentially same way, but possibly more efficiently exploiting the
    //   internal representation of the in-memory RDATA (without involving
    //   expensive name splitting and concatinating).  To avoid resource
    //   allocation it might use some pool of "free (and empty)" internal
    //   RRset.

And in this ticket we'll only need to do the "default version". It
should be essentially straightforward refactoring.

When done, also update auth::Query so it uses this implementation.
It's better to do it before trying to implement the in-memory
optimization in case we miss something in the interface.
