-// Writer implements a ResponseWriter that also does the following:
-// * reverts question section of a packet to its original state.
-//   This is done to avoid the 'Question section mismatch:' error in client.
-// * Defers write to the client if the response code is NXDOMAIN.  This is needed
-//   to enable further search path probing if a search was not successful.
-// * Allow forced write to client regardless of response code.  This is needed to
-//   write the packet to the client if the final search in the path fails to
-//   produce results.
-// * Overwrites response code with Writer.Rcode if the response code
-//   is NXDOMAIN (NameError).  This is needed to support the AutoPath.OnNXDOMAIN
-//   function, which returns a NOERROR to client instead of NXDOMAIN if the final
-//   search in the path fails to produce results.
