Currently proton-C and the various bindings do *not* auto-close contained objects when the container closes. I.e. closing a connection does not close its sessions, closing a session does not close its links etc. Also closing a transport does not automatically close its connection.
I believe there are some reconnect use-cases that require this, e.g. if the transport closes unexpectedly you want to keep the connection and its children around so you can use them to re-build connection state on a new transport. However in the majority of cases it is a huge pain. Look at the existing broker.cpp example, `remove_stale_consumers`. The example isn't even complete: you must implement transport_close, connection_close, link_close (or in C++ sender_close and receiver_close) AND session_close (forgotten in the broker.cpp example) to clean up link resources correctly. I'd like to find a way to automate this that doesn't break the reconnect cases. Ideally I'd like it to be the default behavior unless a reconnect handler is in play. Can that be done with the existing event set or do we need new events?
