    Adapt to CamelSession API changes.
    
    These functions now return new references:
    
      camel_session_add_service()
      camel_session_list_services()
    
    These functions have been renamed and also return new references:
    
      camel_session_get_service()        -> camel_session_ref_service()
      camel_session_get_service_by_url() -> camel_session_ref_service_by_url()
