Asterisk often (but not always) segfaults on startup with res_pjsip_pubsub loaded, due to state being PJSIP_EVSUB_STATE_NULL.

Where the exact issue lies is not currently known, but this kind of thing has been observed on and off since November 2022:

Per one of George's changes, all the pubsub modules should also use this format instead of always returning -1:

static int unload_module(void)
{
    if (ast_shutdown_final()) {
        ast_sip_unregister_subscription_handler(&feature_handler);
        ast_custom_function_unregister(&features_function);
        return 0;
    } else {
        /* Can't unload modules that call ast_sip_register_subscription_handler */
        return -1;
    }
}

In res_pjsip_device_features, this can be a bitfield: unsigned int terminate:1;

Additionally, seized appearances must expire after 30 seconds, so ensure that's the case or make it so.
