polkadot companion: https://github.com/paritytech/substrate/pull/8913

* update Substrate

Co-authored-by: parity-processbot <>

* guide: reversion safety

* guide: manage reversion safety in subsystems

* add leaf status to ActivatedLeaf

* add an LRU-cache to overseer for staleness detection

* update ActivatedLeaf usages in tests to contain status field

* add variant where missed accidentally

* add some helpers to LeafStatus

* address grumbles

* fix approval-checking GRANDPA voting rule

a `None` return value implies to vote on the best, not to vote on the base.

this explicitly changes the logic to vote on the base

* refactor logic out and test

* Use proper host configuration everywhere

* Fix dumb errors

* enable Config for Paras

* fix

* Replace NetworkStatusSinks with Arc<NetworkService>

* update Substrate

* update Substrate

* service: fix missing import

* runtime: bump spec versions

* Add `UsageProvider` trait to `AbstractClient`

* Fix

* validator_discovery: small tweak in retrying logic

* validator_discovery: use timeouts instead

* Introduce polkadot code substitute

This introduces a code substitute for the on-chain wasm of Polkadot from
block
`0x86aa36a140dfc449c30dbce16ce0fea33d5c3786766baa764e33f336841b9e29`
on wards. The underlying problem was that there exists some
miscompilation by the rust compiler in the wasm runtime that results in
state mismatches between the native/wasm runtime of the
the 0.8.30 release. This resulted in blocks being authored by the native
runtime not being importable by nodes using the wasm runtime. The
on-chain wasm is replaced by a wasm build from the 0.8.30 using the
rustc nightly from 1.03.2021.

* update the wasm substitute blob

* log validator index when importing statement

* log validation failures in debug

* network-bridge: downgrade log level of benefit rep change

* remove it as we log it at higher level

* State can be finished due to `Share` message.

Therefoe a task can still be running in that state. Removed panic and
changed state name to reflect possibility of `Share` message.

* bump spec versions in kusama, polkadot and westend again III

* properly bump for the upcoming release
