The genesis header doesn't have the BABE pre-digest and we insert `0` as
slot number. The slot lenience calculation will return the maximum in
this situation. Besides returning the maximum which is not bad at all,
it also prints some a debug message that can be confusing in the first
moment. To prevent printing this debug message, we now just return early
when we see that the parent block is the genesis block.

BabeConsensusDataProvider works with existing chains

Co-authored-by: Bastian Köcher <[email protected]>

Co-authored-by: Bastian Köcher <[email protected]>

* Make consensus `SlotWorker` don't assume a slot is time / duration

This removes the last bit of assumption that a slot is always `time /
duration`. This will be required by parachains where a slot will be the
relay chain block number. Besides this there are also some other drive
by changes. One more notable is that `on_slot` now returns a
`SlotResult` that holds the block and a potential storage proof.

To simplify the implementation and usage of the `SimpleSlotWorker` the
`SlotWorker` trait is now implemented for each type that implements
`SimpleSlotWorker`.

the DHT event stream.

* client/finality-grandpa: Use `Arc<dyn CryptoStore>` instead of SyncXXX

Instead of using `SyncCryptoStorePtr` within `client/finality-grandpa`,
which is a type alias for `Arc<dyn SyncCryptoStore>`, use `Arc<dyn
CryptoStore>`. Benefits are:

1. No additional mental overhead of a `SyncCryptoStorePtr`.

2. Ability for new code to use the asynchronous methods of `CryptoStore`
instead of the synchronous `SyncCryptoStore` methods within
`client/finality-granpa` without the need for larger refactorings.

Note: This commit uses `Arc<dyn CryptoStore>` instead of
`CryptoStorePtr`, as I find the type signature more descriptive. This is
subjective and in no way required.
