/**
* Signature of a function that is called whenever the DNS service
* encounters a DNS request and needs to do something with it. The
* function has then the chance to generate or modify the response by
* calling one of the three "GNUNET_DNS_request_*" continuations.
*
* When a request is intercepted, this function is called first to
* give the client a chance to do the complete address resolution;
* "rdata" will be NULL for this first call for a DNS request, unless
* some other client has already filled in a response.
*
* If multiple clients exist, all of them are called before the global
* DNS. The global DNS is only called if all of the clients'
* functions call GNUNET_DNS_request_forward. Functions that call
* GNUNET_DNS_request_forward will be called again before a final
* response is returned to the application. If any of the clients'
* functions call GNUNET_DNS_request_drop, the response is dropped.
*
* @param cls closure
* @param rh request handle to user for reply
* @param request_length number of bytes in request
* @param request udp payload of the DNS request
