* Grandpa: Store the authority set changes

Store accepted justifications in events.

* GRANDPA justifications: equivocation detection primitives

- made the justification verification logic more customizable
- added support for parsing multiple justifications and extracting
  equivocations
- split the logic into multiple files
- split the errors into multiple enums

* cargo update -p parachain-info

* flush

* it compiles

* clippy

* temporary add more logging to cargo deny

* Revert "temporary add more logging to cargo deny"

This reverts commit 20daa88b.

* fix

* Cumulus parachain stuff

* Cumulus parachain stuff one more

* Millau/Rialto runtimes

* Removed pallet_insecure_randomness_collective_flip

* Millau node

* Removed session historial

* TMP: just try disable all fetches

* Docs in gitlab.yml

* Use `HeaderChainError` in parachains module

* Use MessageProofError instead of 'static str in some places

* Avoid implementing Into<'static str> for some errors

We avoid deriving `Debug` for the structs that we use in the runtime and
we derive `RuntimeDebug` instead in order to avoid bloating th eruntime
with static strs. But implementing `Into<'static str>` does the same. So
in some places it makes sense to replace `Into<'static str>` with `Debug`.

* Move the messages error definition

Move the messages error definition outside of `mod target`

* continue

* fixed all tests

Unify the operating mode for bridge pallets

- define the OperationMode trait and BasicOperatingMode enum
- use the OperationMode trait in all the bridge pallets
- use BasicOperatingMode instead of IsHalted for the Grandpa pallet
- use BasicOperatingMode as part of MessagesOperatingMode

* Appease Clippy

* Update copyright date to 2021

By having the API accept a struct-ified justification we are able to
better utilize the justifications fields for weight calculations.

* Fix some imports

* Make justification wrapper contain decoded justification

* Rename some fields

* Get rid of warnings

This became kinda unnecessary since we could implement the FinalityProof
trait on GrandpaJustification directly.
