* polkadot-service: Make native runtime configurable
This pull requests adds support for configuring the native runtimes used
by polkadot-service. While this whole pr doesn't change that much for
polkadot, besides not having the light-node enabled for the default
polkadot binary. However, downstream projects (parachains) will have a
much better compile time. In cumulus for example the `cargo test --all
--release` is about 4m faster to compile.
* Fixes
* Fix
* Enable rococo-native
* Fix light client
* 🤦
* Fixes
* Create validator_side module
* Subsume Candidate Selection
* Add test to ensure candidate backing logic is correct
* Ensure secondings are adequately cleaned up and address test flakyness
* Address Feedback
* 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
* 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
