// implement state serialization if it's needed. To test the serialization one
// can set a custom `g_handover_state_transformer_for_test` at startup, link to
// the dcSCTP tests and run the resulting binary. Custom function can serialize
// and deserialize the passed state. All dcSCTP handover tests call
// `g_handover_state_transformer_for_test`. If some part of the state is
// serialized incorrectly or is forgotten, high chance that it will fail the
// tests.
