> Change ownership model for pn_connection_t and pn_listener_t managed by the proactor: instead of proactor freeing automatically after the final event, the user must free on or after the final event.
> There are 2 basic use cases:
> 1. Free connection/listener immediately on the last event.
> 2. Keep connection/listener in memory until all application pointers are cleaned up.
> Proactor ownership does 1. very well, but makes 2. very difficult without
> exposing reference-counts.
> User ownership supports both reasonably easily: 1. is implemented by calling pn_connection_free() or pn_listener_free() in the event handler on the last event.
