Michal Kucharczyk 7a10154188 BlockId removal: runtime-api refactor (#13255)
* BlockId removal: refactor of runtime API

It changes the arguments of:
- `ApiExt` methods:  `has_api`, `has_api_with`, `api_version`
- `CallApiAt` method: `runtime_version_at`
from: `BlockId<Block>` to: `Block::Hash`

It also changes the first argument of all generated runtime API calls from: `BlockId<Block>` to: `Block::Hash`

This PR is part of BlockId::Number refactoring analysis (paritytech/substrate#11292)

* BlockId removal: refactor of runtime API - tests

- tests adjusted to new runtime API,
- some tests migrated from block number to block hash

* benchmarking-cli: BlockId(0) migrated to info().genesis_hash

`runtime_api.call()` now requires the block hash instead of BlockId::Number.
To access the genesis hash widely used in benchmarking engine the Client
was constrained to satisfy `sp_blockchain::HeaderBackend<Block>` trait
which provides `info().genesis_hash`.

* trivial: api.call(BlockId) -> api.call(Hash)

- Migrated all `runtime_api.calls` to use Hash
- Noteworthy (?):
-- `validate_transaction_blocking` in transaction pool,

* CallApiAtParams::at changed to Block::Hash

* missed doc updated

* Apply suggestions from code review

* ".git/.scripts/commands/fmt/fmt.sh"

* BlockId removal: Benchmark::consumed_weight

Little refactor around `Benchmark::consumed_weight`: `BlockId` removed.

* at_hash renamed

* wrong merge fixed

* beefy worker: merged with master

* beefy: tests: missing block problem fixed

* Apply review suggestion

* fix

Aura (Authority-round) consensus in substrate.

Aura works by having a list of authorities A who are expected to roughly agree on the current time. Time is divided up into discrete slots of t seconds each. For each slot s, the author of that slot is A[s % |A|].

The author is allowed to issue one block but not more during that slot, and it will be built upon the longest valid chain that has been seen.

Blocks from future steps will be either deferred or rejected depending on how far in the future they are.

NOTE: Aura itself is designed to be generic over the crypto used.
