@keszybz's right on https://github.com/systemd/systemd/pull/18248#issuecomment-760798473: swapping out the userdata pointer of a live varlink connection is iffy. Let's fix this by making the userdata inheritance from VarlinkServer object to the Varlink connection object optional: we want it for most cases, but not all, i.e. all those cases where the calls implemented as varlink methods are stateless and can be answered synchronously. For the other cases (i.e. where we want per-connection objects that wrap the asynchronous operation as it goes on) let's not do such inheritance but initialize the userdata pointer only once we have it. THis means the original manager object must be manually retrieved from the VarlinkServer object, which in turn needs to be requested from the Varlink connection object. The userdata inheritance is now controlled by the VARLINK_INHERIT_USERDATA flag passed at VarlinkServer construction. Alternative-to: #18248
