* Check candidate signatures before including them in `set_heads`

This work around the bug described in: https://github.com/paritytech/polkadot/issues/1327

We check the candidate signatures in `create_inherent` to ensure that
all are valid. If one isn't valid, we don't include any candidate for
the current inherent.

* impl ProvideInherent for InclusionInherent

* reduce import churn; correct expect message

* move inclusion inherent identifier into primitives

It's not clear precisely why this is desired, but it's a pattern
I've seen in several places, so I'm going this to be on the
safe side. Worst case, we can revert this commit pretty easily.

* bump kusama spec_version to placate CI

* add license header

* empty commit; maybe github will notice the one with changes

* add sanity check to only include valid inherents

* Make `produce_candidate` return an `Option`

Instead of `produce_candidate` returning a `Result`, it should return an
`Option`. The only supported error was `InvalidHead` anyway and Cumulus
will take care to print appropriate information on what failed and
Polkadot can just ignore it.

* Fix warning

  C1 label is enforeced by check-labels anyway, saves us some API calls)

* Ensure priorities >C1-low aren't labelled B0-silent

* Use /dns4/ rather than /dns/

* Update polkadot.json

* add signed wrapper, typedef SignedStatement

* typedef SignedAvailabilityBitfield

* implement Signed wrapper

This is strictly an addition as of this commit; nothing is yet
changed in existing behavior.

* inline getters, remove review comment

* move EncodeAs, Signed from node::primitives to primitives::parachain

* Refactor SignedAvailabilityBitfield to use Signed

* don't double-encode real payload

This isn't an ideal solution, because it depends on the
implementation details of how SCALE encodes tuples, but OTOH
that behavior seems unlikely to change anytime soon.

* fix build errors

* cause the runtime to build properly with the new changes

Not sure why cargo check didn't catch this earlier; oh well.

* fix runtime tests and separate SignedStatement from SignedFullStatement

* better explain why CompactStatement exists
