 * The initial version of this code was written by Dragos Vingarzan
 * (dragos(dot)vingarzan(at)fokus(dot)fraunhofer(dot)de and the
 * Fruanhofer Institute. It was and still is maintained in a separate
 * branch of the original SER. We are therefore migrating it to
 * Kamailio/SR and look forward to maintaining it from here on out.
 * 2011/2012 Smile Communications, Pty. Ltd.
 * ported/maintained/improved by
 * Jason Penton (jason(dot)penton(at)smilecoms.com and
 * Richard Good (richard(dot)good(at)smilecoms.com) as part of an
 * effort to add full IMS support to Kamailio/SR using a new and
 * improved architecture
 *
 * NB: Alot of this code was originally part of OpenIMSCore,
 * FhG Focus. Thanks for great work! This is an effort to
 * break apart the various CSCF functions into logically separate
 * components. We hope this will drive wider use. We also feel
 * that in this way the architecture is more complete and thereby easier
 * to manage in the Kamailio/SR environment

 * The list of AVPs must be declared in the following format:

 * 		cdp_avp_add(<avp_name>.<vendor_id>,<flags>,<avp_type>,<data_type>)
 * 		or
 * 		cdp_avp_add_ptr(<avp_name>.<vendor_id>,<flags>,<avp_type>,<data_type>)
 *
 * 		cdp_avp_get(<avp_name>.<vendor_id>,<avp_type>,<data_type>)
 *
 * or, to add both add and get at once:

 * 		or
 * 		cdp_avp_ptr(<avp_name>.<vendor_id>,<flags>,<avp_type>,<data_type>)
 *
 * The add macros ending in _ptr will generate function with the extra AVPDataStatus data_do parameter
 *
 * Parameters:
 *  - avp_name - a value of AVP_<avp_name> must resolve to the AVP code
 *  - vendor_id - an int value
 *  - flags	- AVP Flags to add to the AVP
 *  - avp_type - an avp type for which a function was defined a
 * 				int cdp_avp_get_<avp_type>(AAA_AVP *avp,<data_type> *data)
 * 		Some valid suggestions (and the data_type):
 *
 *  			OctetString 	- str
 *  			Integer32		- int32_t
 *  			Integer64 		- int64_t
 *  			Unsigned32 		- uint32_t
 *  			Unsigned64 		- uint64_t
 *  			Float32 		- float
 *  			Float64 		- double
 *  			Grouped 		- AAA_AVP_LIST
 *
 *  			Address 		- ip_address
 *  			Time 			- time_t
 *  			UTF8String 		- str
 *  			DiameterIdentity- str
 *  			DiameterURI		- str
 *  			Enumerated		- int32_t
 *  			IPFilterRule	- str
 *  			QoSFilterRule	- str
 *  - data_type - the respective data type for the avp_type defined above
 *
 *  The functions generated will return 1 on success or 0 on error or not found
 *  The prototype of the function will be:
 *
 *  	int cdp_avp_get_<avp_name_group>(AAA_AVP_LIST list,<data_type> *data,AAA_AVP **avp_ptr)
 *
 *
 *
 *  For Grouped AVPs with 2 or 3 known inside AVPs, you can define a shortcut function which will find the group and
 *  also extract the 2 or 3 AVPs.
 *  Do not define both 2 and 3 for the same type!
 *

 *
 *		cdp_avp_get3(<avp_name_group>.<vendor_id_group>,<flags_group>,<avp_name_1>,<data_type_1>,<avp_name_2>,<data_type_2>,<avp_name_3>,<data_type_3>)

 *
 * 	 or, to add both add and get at once:

 * 		cdp_avp3(<avp_name_group>.<vendor_id_group>,<flags_group>,<avp_name_1>,<data_type_1>,<avp_name_2>,<data_type_2>)
 *
 *  avp_name_group - a value of AVP_<avp_name_group> must resolve to the AVP code of the group
 *
 *  vendor_id_group - an int value
 *
 *  avp_name_N	- the name of the Nth parameter.
 *  	Previously, a cdp_avp_get(<avp_name_N>,<vendor_id_N>,<avp_type_N>,<data_type_N>) must be defined!
 *
 *  data_type_N	- the respective data type for avp_type_N (same as <data_type_N)
 *
 *  The functions generated will return the number of found AVPs inside on success or 0 on error or not found
 *  The prototype of the function will be:
 *
 *  	int cdp_avp_get_<avp_name_group>_Group(AAA_AVP_LIST list,<data_type_1> *avp_name_1,<data_type_2> *avp_name_2[,<data_type_3> *avp_name_3],AAA_AVP **avp_ptr)
 *
 *  Note - generally, all data of type str will need to be defined with ..._ptr
 *  Note - Groups must be defined with:
 *  	 cdp_avp_add_ptr(...) and data_type AAA_AVP_LIST*
 *  	 cdp_avp_get(...) and data_type AAA_AVP_LIST
