* expose GRANDPA RPC API from Millau node

* fmt

* Add Rialto as a target for the Millau node

* Rename Rialto module to Rialto-PoA

This will reduce confusion as the Millau runtime has a
Rialto module as well which refers to the Substrate chain.

* Add Millau as a target for the Rialto node

* Be more explicit about Rialto PoA related code

* Missed some name changes in the Ethereum PoA relay

* Re-export Substrate pallet structs used by node

* Remove `first_scheduled_change` of Millau in Rialto node

* MillauHeaderApi and RialtoHeaderApi

* post-merge fixes + TODOs + compilation

* Remove the Substrate primitives crate

The types here were only used in one place, the pallet itself. If other
components start using these types we can considering moving them back
into a standalone crate.

* Start trying to integrate justification module

* Make Substrate blocks configurable in Pallet

* WIP: Try and generalize justification test helpers

* Fix tests which use "real" justifications

* Put common test helpers alongside mock code

* Use common helper for creating headers

* Remove usage of UintAuthorityId

This change favours the use of the Ed25519Keyring authorities
in order to keep things consistent with the tests.

* Derive `RuntimeDebug` instead of `Debug`

* Add `Paramter` as a trait constraint on config types

Since we use these types as part of the dispatchable functions
we should explicitly require this.

* Enforce that hasher output matches expected hash type

* Accept headers over indexes when making test justifications

* Check that authority sets are valid

* Make Clippy happy

* Apply correct Clippy fix

* Move justification code into primitives module
