* -PBS_resc() - internal common code for sending resource requests

* @par Functionality:
* Formats and sends the requests for pbs_rescquery(), pbs_rescreserve(),
* and pbs_rescfree(). Note, while the request is overloaded for all
* three, each has its own expected reply format.
*
* @param[in] c - communication handle
* @param[in] reqtype - request type
* @param[in] rescl- pointer to resource list
* @param[in] ct - count of query strings
* @param[in] rh - resource handle
*
* @return int
* @retval 0 success
* @retval !0 error
