* grandpa: enable observer for light client

* update Substrate

* service: fix missing import

* runtime: bump spec versions

Co-authored-by: parity-processbot <>

It should rather be updated manually with proper `Cargo.lock` updates at least until we switch to crates.io versions. See #3109 as an example of that (bad) update.

* 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

* update Substrate

* 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
