*
* @note Always appends the new pair to the end of the list.
*
* @param rh a handle to parsed configuration.
* @param list a #VALUE_PAIR array of values; initially must be %NULL.
* @param attrid The attribute of the pair to add (e.g., %PW_USER_NAME).
* @param pval the value (e.g., the actual username).
* @param len the length of @pval, or -1 if to calculate (in case of strings).
* @param vendorpec The vendor ID in case of a vendor specific value - 0 otherwise.
* @return pointer to added a/v pair upon success, NULL pointer upon failure.
