* Emit events for active connection close and fix `disconnect()`. The `Network` does currently not emit events for actively closed connections, e.g. via `EstablishedConnection::close` or `ConnectedPeer::disconnect()`. As a result, when actively closing connections, there will be `ConnectionEstablished` events emitted without eventually a matching `ConnectionClosed` event. This seems undesirable and has the consequence that the `Swarm::ban_peer_id` feature in `libp2p-swarm` does not result in appropriate calls to `NetworkBehaviour::inject_connection_closed` and `NetworkBehaviour::inject_disconnected`. Furthermore, the `disconnect()` functionality in `libp2p-core` is currently broken as it leaves the `Pool` in an inconsistent state. This commit does the following: 1. When connection background tasks are dropped (i.e. removed from the `Manager`), they always terminate immediately, without attempting an orderly close of the connection. 2. An orderly close is sent to the background task of a connection as a regular command. The background task emits a `Closed` event before terminating. 3. `Pool::disconnect()` removes all connection tasks for the affected peer from the `Manager`, i.e. without an orderly close, thereby also fixing the discovered state inconsistency due to not removing the corresponding entries in the `Pool` itself after removing them from the `Manager`. 4. A new test is added to `libp2p-swarm` that exercises the ban/unban functionality and places assertions on the number and order of calls to the `NetworkBehaviour`. In that context some new testing utilities have been added to `libp2p-swarm`. This addresses https://github.com/libp2p/rust-libp2p/issues/1584. * Update swarm/src/lib.rs Co-authored-by: Toralf Wittner <tw@dtex.org> * Incorporate some review feedback. * Adapt to changes in master. * More verbose panic messages. * Simplify There is no need for a `StartClose` future. * Fix doc links. * Further small cleanup. * Update CHANGELOGs and versions.
