      * client/network-gossip/src/bridge: Finish when network even stream closes

Previously within `<GossipEngine as Future>::poll` one would poll the
`network_event_stream` ignoring all messages other than
`Poll::Ready(Some())`. Ignoring `Poll::Ready(None)` leads to a panic on
the next poll of the stream, gien that it is not fused.

By design `network_event_stream` does not close unless an unbounded send
into it fails, or the `NetworkWorker` gets shut down.

> The stream never ends (unless the `NetworkWorker` gets shut down).
> (client/network/src/service.rs)

An `unbounded_send` to fail on an unbounded channel is unlikely. The
`NetworkWorker` shutting down is not unlikely. In such case the
`GossipEngine` should shut down as well.

With this patch a `<GossipEngine as Future>` finishes on
`Poll::Ready(None)` returned from `network_event_stream`.

* client/finality-grandpa/communication: Error on gossip engine finished

Have `<NetworkBridge as Future>::poll` return `Poll::Ready(Err)` instead
of `Poll::Ready(Ok)` to be consistent with the handling of the neighbor
packet worker stream and the gossip validator report stream. Both `Err`
as well as `Ok` shut down the `NetworkBridge` as well as the
`VoterWorker`.

* client/network-gossip/src/bridge: Add regression test

* client/network-gossip: Move substrate test client to dev dependencies

* client/network-gossip: Remove TODO

Addressed in a follow up pull request.

* client/network-gossip/bridge: Put match on newline after loop

* client/finality-grandpa/src/observer: Fix regression test

Make sure the event stream sender side is not dropped till the end.

      sc-network: Return on Poll::Pending. (#5295) · c6f1ba9e
      Toralf Wittner authored 
      If polling encounters a `Poll::Pending` we need to return it instead of
continuing the loop which may turn it into a blocking operation, causing
problems with executors.

      Move runtime upgrade to `frame-executive` (#5197) · 064ca16f
      Bastian Köcher authored 
      * Move runtime upgrade to `frame-executive`

Instead of storing the runtime upgraded in the space of `frame-system`,
this moves it to `frame-executive`. We also start storing the
`spec_version` and `impl_version` the last runtime upgrade was applied.

This scheme has multiple advantages:
- We don't need to make sure that runtime upgrade was set.
- This will work in the future when we want to test a runtime upgrade,
because the `on_runtime_upgrade` will be executed automatically when the
runtime changes.

* Move `LAST_RUNTIME_UPGRADE` key to `frame-executive`

* Add some more documentation

* Make sure `spec_version` always increases between runtime upgrades

* Fix test

* Upgrade `parity-multiaddr` to fix compilation

* Also check if the `spec_name` changed

* Remove `RuntimeUpgraded` storage entry

* Don't run on genesis

      client/network-gossip: Merge GossipEngine and GossipEngineInner (#5042) · 78cdd3bf
      Max Inden authored 
      * client/network-gossip: Merge GossipEngine and GossipEngineInner

Given that GossipEngine and GossipEngineInner are not shared between
threads anyone (public interface + background tasks), neither depends on
being Send or Sync. Thus one can merge the two as done in this patch.
One only needs to wrap an `Arc<Mutex<>>` around the whole structure when
the owner (e.g. finality-grandpa) needs to share the gossip engine
between threads.

* client/finality-grandpa: Wrap GossipEngine in Arc Mutex & lock it on use

GossipEngine in itself has no need to be Send and Sync, given that it
does not rely on separately spawned background tasks anymore. Given that
finality-grandpa shares the `NetworkBridge` potentially between threads
its components need to be clonable, thus this patch wraps `GossipEngine`
in an `Arc<Mutex<>>`.
