* Make block sync service customizable
This change allows user to have their own network block logic, for example, we'd like to disable
the builtin block sync service when using another syncing approach.

* Prepare `sc-network` for `ProtocolController`/`NotificationService`
The upcoming notification protocol refactoring requires that protocols
are able to communicate with `sc-network` over unique and direct links.
This means that `sc-network` side of the link has to be created before
`sc-network` is initialized and that it is allowed to consume the object
as the receiver half of the link may not implement `Clone`.
Remove request-response and notification protocols from `NetworkConfiguration`
and create a new object that contains the configurations of these protocols
and which is consumable by `sc-network`. This is needed needed because, e.g.,
the receiver half of `NotificationService` is not clonable so `sc-network`
must consume it when it's initializing the protocols in `Notifications`.
Similar principe applies to `PeerStore`/`ProtocolController`: as per current
design, protocols are created before the network so `Protocol` cannot be
the one creating the `PeerStore` object. `FullNetworkConfiguration` will be
used to store the objects that `sc-network` will use to communicate with
protocols and it will also allow protocols to allocate handles so they
can directly communicate with `sc-network`.

* 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.

This removes the deprecated batch verification. This was actually never really activated.
Nevertheless, we need to keep the host functions around to support old runtimes which may import
these host functions. However, we do not give access to these functions anymore. This means that any new
runtime can not call them anymore. The host function implementations we keep will not do batch verification and will
instead fall back to the always existing option of directly verifying the passed signature.
`finish_batch_verification` will return the combined result of all the batch verify calls.
This removes the `TaskExecutorExt` which only existed to support the batch verification. So, any
code that used this extension can just remove the registration of them. It also removes
`SignatureBatching` that was used by `frame-executive` to control the batch verification.
However, there wasn't any `Verify` implementation that called the batch verification functions.
* Attempt to relieve pressure on `mpsc_network_worker`
`SyncingEngine` interacting with `NetworkWorker` can put a lot of strain
on the channel if the number of inbound connections is high. This is
because `SyncingEngine` is notified of each inbound substream which it
then can either accept or reject and this causes a lot of message
exchange on the already busy channel.
Use a direct channel pair between `Protocol` and `SyncingEngine`
to exchange notification events. It is a temporary change to alleviate
the problems caused by syncing being an independent protocol and the
fix will be removed once `NotificationService` is implemented.
* Apply review comments
* fixes
* trigger ci
* Fix tests
Verify that both peers have a connection now that the validation goes
through `SyncingEngine`. Depending on how the tasks are scheduled,
one of them might not have the peer registered in `SyncingEngine` at which
point the test won't make any progress because block announcement received
from an unknown peer is discarded.
Move polling of `ChainSync` at the end of the function so that if a block
announcement causes a block request to be sent, that can be sent in the
same call to `SyncingEngine::poll()`.

* 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`.

* 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)
