This can happen under heavy load - no value in warning here.
Scenario this happens:
- New slot
- We get asked about what fork to build on
- We start building (create inherent gets called)
- We learn about a better fork (but Babe does not care as it already has a fork)
- 6 seconds passed - New slot
- Babe asks about what for to build on - we answer with the best block we learned about 6 seconds ago (slightly after we got asked the last time)
- We start building (on that old block)
- Milliseconds later we learn about a new block (the one from the slot we are actually in now)
- We kick the old leaf -> create inherent fails

* Don't store available data on disputes
If there are lots of disputes, this leads to blowing up disk space on
validators. Rob luckily remembered that we do store the full
availability in participation.
The argument in the code does not make too much sense with the current
implementation, as no validator will ever request anything else from us,
than the one piece we are meant to posess.
* Fix warnings.
* Fix compile warnings
* Remove redundant field.

* Don't import backing statements directly
into the dispute coordinator. This also gets rid of a redundant
signature check. Both should have some impact on backing performance.
In general this PR should make us scale better in the number of parachains.
Reasoning (aka why this is fine):
For the signature check: As mentioned, it is a redundant check. The
signature has already been checked at this point. This is even made
obvious by the used types. The smart constructor is not perfect as
discussed [here](https://github.com/paritytech/polkadot/issues/3455),
but is still a reasonable security.
For not importing to the dispute-coordinator: This should be good as the
dispute coordinator does scrape backing votes from chain. This suffices
in practice as a super majority of validators must have seen a backing
fork in order for a candidate to get included and only included
candidates pose a threat to our system. The import from chain is
preferable over direct import of backing votes for two reasons:
1. The import is batched, greatly improving import performance. All
backing votes for a candidate are imported with a single import.
And indeed we were able to see in metrics that importing votes
from chain is fast.
2. We do less work in general as not every candidate for which
statements are gossiped might actually make it on a chain. The
dispute coordinator as with the current implementation would still
import and keep those votes around for six sessions.
While redundancy is good for reliability in the event of bugs, this also
comes at a non negligible cost. The dispute-coordinator right now is the
subsystem with the highest load, despite the fact that it should not be
doing much during mormal operation and it is only getting worse
with more parachains as the load is a direct function of the number of statements.
We'll see on Versi how much of a performance improvement this PR

* Review feedback.
In particular: Add note about disputes of non included candidates.
* Incorporate Review Remarks
* Get rid of superfluous space.
* Tidy up import logic a bit.
Logical vote import is now separated, making the code more readable and
maintainable.
Also: Accept import if there is at least one invalid signer that has not
exceeded its spam slots, instead of requiring all of them to not exceed
their limits. This is more correct and a preparation for vote batching.

We are awaiting on the oneshot anyways, so we have back pressure. By
using the unbounded channel make log messages like the following less
likely (due to higher priority):

* Double grandpa gossip duration.
* Make resend period slightly larger.
So it won't get triggered by additional grandpa delay.
* Bump other values as well.
* Don't change gossip duration on Polkadot.
(and Westend as it is meant to be a testbed for Polkadot)
* Don't wait for dispute coordinator
in backing and approval-voting - we are single threaded there, so this
is blocking everything.
* Add missing import.
* Don't warn on dropped receiver.
* First step in implementing https://github.com/paritytech/polkadot/issues/4386
This PR:
- Reduces MAX_UNSHARED_UPLOAD_TIME to 150ms
- Increases timeout on collation fetching to 1200ms
- Reduces limit on needed backing votes in the runtime
This PR does not yet reduce the number of needed backing votes on the
node as this can only be meaningfully enacted once the changed limit in
the runtime is live.
