/**
* This function registers a generic callback function. The major and
* minor values are used to set the new_callback function into a global
* static multi-dimensional array of type struct snmp_gen_callback.
* The function makes sure to append this callback function at the end
* of the link list, snmp_gen_callback->next.
*
* @param major is the SNMP callback major type used
* - SNMP_CALLBACK_LIBRARY
* - SNMP_CALLBACK_APPLICATION
*
* @param minor is the SNMP callback minor type used
* - SNMP_CALLBACK_POST_READ_CONFIG
* - SNMP_CALLBACK_STORE_DATA
* - SNMP_CALLBACK_SHUTDOWN
* - SNMP_CALLBACK_POST_PREMIB_READ_CONFIG
* - SNMP_CALLBACK_LOGGING
* - SNMP_CALLBACK_SESSION_INIT
*
* @param new_callback is the callback function that is registered.
*
* @param arg when not NULL is a void pointer used whenever new_callback
* function is exercised.
*
* @return
* Returns SNMPERR_GENERR if major is >= MAX_CALLBACK_IDS or minor is >=
* MAX_CALLBACK_SUBIDS or a snmp_gen_callback pointer could not be
* allocated, otherwise SNMPERR_SUCCESS is returned.
* - \#define MAX_CALLBACK_IDS 2
* - \#define MAX_CALLBACK_SUBIDS 16

* @see snmp_call_callbacks
