This commit introduces a new concept called `NotificationService` which
allows Polkadot protocols to communicate with the underlying
notification protocol implementation directly, without routing events
through `NetworkWorker`. This implies that each protocol has its own
service which it uses to communicate with remote peers and that each
`NotificationService` is unique with respect to the underlying
notification protocol, meaning `NotificationService` for the transaction
protocol can only be used to send and receive transaction-related
notifications.
The `NotificationService` concept introduces two additional benefits:
* allow protocols to start using custom handshakes
* allow protocols to accept/reject inbound peers
Previously the validation of inbound connections was solely the
responsibility of `ProtocolController`. This caused issues with light
peers and `SyncingEngine` as `ProtocolController` would accept more
peers than `SyncingEngine` could accept which caused peers to have
differing views of their own states. `SyncingEngine` would reject excess
peers but these rejections were not properly communicated to those peers
causing them to assume that they were accepted.
With `NotificationService`, the local handshake is not sent to remote
peer if peer is rejected which allows it to detect that it was rejected.
This commit also deprecates the use of `NetworkEventStream` for all
notification-related events and going forward only DHT events are
provided through `NetworkEventStream`. If protocols wish to follow each
other's events, they must introduce additional abtractions, as is done
for GRANDPA and transactions protocols by following the syncing protocol
through `SyncEventStream`.

The `BlockBuilderProvider` was a trait that was defined in
`sc-block-builder`. The trait was implemented for `Client`. This
basically meant that you needed to import `sc-block-builder` any way to
have access to the block builder. So, this trait was not providing any
real value. This pull request is removing the said trait. Instead of the
trait it introduces a builder for creating a `BlockBuilder`. The builder
currently has the quite fabulous name `BlockBuilderBuilder` (I'm open to
any better name 😅). The rest of the pull request is about
replacing the old trait with the new builder.
# Downstream code changes
If you used `new_block` or `new_block_at` before you now need to switch
it over to the new `BlockBuilderBuilder` pattern:
```rust
// `new` requires a type that implements `CallApiAt`.
let mut block_builder = BlockBuilderBuilder::new(client)
// Then you need to specify the hash of the parent block the block will be build on top of
.on_parent_block(at)
// The block builder also needs the block number of the parent block.
// Here it is fetched from the given `client` using the `HeaderBackend`
// However, there also exists `with_parent_block_number` for directly passing the number
.fetch_parent_block_number(client)
.unwrap()
// Enable proof recording if required. This call is optional.
.enable_proof_recording()
// Pass the digests. This call is optional.
.with_inherent_digests(digests)
.build()
.expect("Creates new block builder");
```

* substrate-test-runtime migrated to pure-frame based
* test block builder: helpers added
* simple renaming
* basic_authorship test adjusted
* block_building storage_proof test adjusted
* babe: tests: should_panic expected added
* babe: tests adjusted
ConsensusLog::NextEpochData is now added by pallet_babe as
pallet_babe::SameAuthoritiesForever trigger is used in runtime config.
* beefy: tests adjusted
test-substrate-runtime is now using frame::executive to finalize the
block. during finalization the digests stored during block execution are
checked against header digests:
https://github.com/paritytech/substrate/blob/91bb2d29ca905599098a5b35eaf24867c4fbd60a/frame/executive/src/lib.rs#L585-L591
It makes impossible to directly manipulate header's digets, w/o
depositing logs into system pallet storage `Digest<T: Config>`.
Instead of this dedicated extrinsic allowing to store logs items
(MmrRoot / AuthoritiesChange) is used.

* Move import queue out of `sc-network`
Add supplementary asynchronous API for the import queue which means
it can be run as an independent task and communicated with through
the `ImportQueueService`.
This commit removes removes block and justification imports from
`sc-network` and provides `ChainSync` with a handle to import queue so
it can import blocks and justifications. Polling of the import queue is
moved complete out of `sc-network` and `sc_consensus::Link` is
implemented for `ChainSyncInterfaceHandled` so the import queue
can still influence the syncing process.
* Move stuff to SyncingEngine
* Move `ChainSync` instanation to `SyncingEngine`
Some of the tests have to be rewritten
* Move peer hashmap to `SyncingEngine`
* Let `SyncingEngine` to implement `ChainSyncInterface`
* Introduce `SyncStatusProvider`
* Move `sync_peer_(connected|disconnected)` to `SyncingEngine`
* Implement `SyncEventStream`
Remove `SyncConnected`/`SyncDisconnected` events from
`NetworkEvenStream` and provide those events through
`ChainSyncInterface` instead.
Modify BEEFY/GRANDPA/transactions protocol and `NetworkGossip` to take
`SyncEventStream` object which they listen to for incoming sync peer
events.
* Introduce `ChainSyncInterface`
This interface provides a set of miscellaneous functions that other
subsystems can use to query, for example, the syncing status.
* Move event stream polling to `SyncingEngine`
Subscribe to `NetworkStreamEvent` and poll the incoming notifications
and substream events from `SyncingEngine`.
The code needs refactoring.
* Make `SyncingEngine` into an asynchronous runner
This commits removes the last hard dependency of syncing from
`sc-network` meaning the protocol now lives completely outside of
`sc-network`, ignoring the hardcoded peerset entry which will be
addressed in the future.
Code needs a lot of refactoring.
* Fix warnings
* Code refactoring
* Use `SyncingService` for BEEFY
* Use `SyncingService` for GRANDPA
* Remove call delegation from `NetworkService`
* Remove `ChainSyncService`
* Remove `ChainSync` service tests
They were written for the sole purpose of verifying that `NetworWorker`
continues to function while the calls are being dispatched to
`ChainSync`.
