  Thread cleanup service allows a OS thread to free resources allocated
  for specific thread, during thread exit. Component can register for
  thread cleanup handler, for desired OS threads.
 
  At thread exit, the service 'thread_cleanup_handler' implemented
  by the component is invoked by MySQL server.
 
  @section Registering thread cleanup.
 
  The service can be instantiated using the registry service with the
  "thread_cleanup_register" name.
 
  @code
  SERVICE_TYPE(registry) *registry = mysql_plugin_registry_acquire();
  my_service<SERVICE_TYPE(thread_cleanup_register)>
                                svc("thread_cleanup_register", registry);
  if (svc.is_valid()) {
    // The service is ready to be used
  }
  @endcode
 
  The code below demonstrates way to register thread cleanup for a thread
  from a component. Note that we cannot deregister thread cleanup event. In
  case the component is uninstalled, then the thread cleanup is NO-OP.
 
  @code
  svc->register_cleanup("implementation_name");
  @endcode
