@brief Add endpoint security for a protocomm instance
This API will bind a security session establisher to the specified endpoint name, along with any proof of possession that may be required for authenticating a session client.
@note
- An endpoint must be bound to a valid protocomm instance,
created using 
protocomm_new(). - The choice of security can be any 
protocomm_security_tinstance. Choicesprotocomm_security0andprotocomm_security1andprotocomm_security2are readily available. 
@param[in] pc Pointer to the protocomm instance @param[in] ep_name Endpoint identifier(name) string @param[in] sec Pointer to endpoint security instance @param[in] sec_params Pointer to security params (NULL if not needed) The pointer should contain the security params struct of appropriate security version. For protocomm security version 1 and 2 sec_params should contain pointer to struct of type protocomm_security1_params_t and protocmm_security2_params_t respectively. The contents of this pointer must be valid till the security session has been running and is not closed. @return
