Reconnection issues

[floe]

Still prone to hanging when clients reconnect quickly, or in short succession.

Suggestion: don't exit on pipeline error ("SCTP association error state")?

(Hopefully) solved via a0f6815.

Not yet solved 😑 Root cause seems to be if a client dis- and reconnects (or a second client connects) before all the GStreamer plumbing is in place.

[floe]

More precisely: error seems to occur when the client disconnects again before all streams have fully started, leading to non-deterministic caps negotiation errors later on.

The same (or a similar) issue also seems to occur after several regular client disconnections at some point, where parts of the pipeline just stop streaming.
