* Don't initialize block when calling runtime APIs
* Adapt check_validation_outputs
We split the code path for the inclusion and for the commitments checking.
* Slap #[skip_initialize_block] on safe runtime APIs
That is, those that should not be affected by this attribute
* Make `Scheduled` not ephemeral
So that it is persisted in the storage and ready to be inspected
by the runtime APIs. This is in contrast to what was before, where we
would remove the storage entry and then rely on the scheduling performed
by `on_initialize` again.

Previously, it was the beginning of the next block. This allows us to

* Make it possible to calculate the storage as often as you want
So, until now each Substrate based blockchain has calculated the storage
root once, at the end of the block. Now there is Frontier that wants to
calculate some intermediate storage root. However this failed on block
import. The problem with that was the extrinsics root. When building the
block we stored `Default::default()` as extrinsics root, because yeah,
we don't know the extrinsics root before finishing the block. At the end
this extrinsics root was then calculated. But on block import we passed
the already known extrinsics root. This was no problem, as we removed
this value at the end of the block. However when you all the storage
root in between, that changes the storage root between block building
and block import.
This pr changes this behavior. It removes the `ExtrinsicsRoot` storage
entry and also doesn't pass it anymore to `System::initialize`. By doing
it, we remove the difference in the storage and fix the storage root mismatch.

* Update common block in sync after importing blocks of a peer
This updates the sync code to update the common block of a peer, after
we have imported blocks from this peer. This fixes a bug for when we are
connected to one or more nodes that are doing a full sync as our node.
Nodes in full sync will not announce new blocks, as we don't send import
notifications on full sync. The problem as now that we were connected to
some peer that reported some low number as its best and we tried to sync
these blocks. But, as we did not update the common block of this peer,
we would sync these blocks over and over again. Being captured in some
time warp.
The solution to this problem is that we increase the common number as we
import blocks from this peer.

- There was a bug that resulted in only getting one candidate per block
as the candidates were put into the hashmap with the relay block hash as
key. The solution for this is to use the candidate hash and the relay
block hash as key.
- We stored received/sent messages with the candidate hash and chunk
index as key. The candidate hash wasn't required in this case, as the
messages are already stored per candidate.

Right now if the collation is not happening one will have to sprinkle
log statements and then recompile the code. It's doubly annoying if that
happens when working with Cumulus: that means one has to resort to
.cargo/config's `paths` or `diener`, which both are not ideal.
This just adds some verbose logging to save the investigators some time
when looking why the collations are not happening

* Skip slot lenience on first block in BABE (#7515)
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.

deprecated (see https://github.com/rust-lang-nursery/failure/pull/347)
* make LocalCallExecutor public (#7528)
* Fix some weirdness in `offchain_worker` (#7541)
We call `offchain_worker` with the state of the imported block and pass
the header of this block. However in the runtime we call all
`offchain_worker` functions with the number of the parent block. Besides
that we also pass all digests and not only the pre runtime digests. In
the context where the offchain worker is executed we have all digests, so
there is no real reason to only pass pre runtime digests. Another fix is
that we also insert the hash of the current header into the block hash map.
