Bastian Köcher 2675741a09 Rework inherent data client side (#8526)
* Lol

* Yeah

* Moare

* adaasda

* Convert AURA to new pallet macro

* AURA: Switch to `CurrentSlot` instead of `LastTimestamp`

This switches AURA to use `CurrentSlot` instead of `LastTimestamp`.

* Add missing file

* Update frame/aura/src/migrations.rs

* Remove the runtime side provide inherent code

* Use correct weight

* Add TODO

* Remove the Inherent from AURA

* 🤦

* Remove unused stuff

* Update primitives authorship

* Fix babe inherent data provider

* Fix consensus-uncles

* Fix BABE

* Do some further changes to authorship primitives... :D

* More work

* Make it compile the happy path

* Make it async!

* Take hash

* More stuff

* Hacks

* Revert "Hacks"

This reverts commit cfffad88668cfdebf632a59c4fbfada001ef8251.

* Fix

* Make `execute_block` return the final block header

* Move Aura digest stuff

* Make it possible to disable equivocation checking

* Fix fix fix

* Some refactorings

* Comment

* Fixes fixes fixes

* More cleanups

* Some love

* Better love

* Make slot duration being exposed as `Duration` to the outside

* Some slot info love

* Add `build_aura_worker` utility function

* Copy copy copy

* Some stuff

* Start fixing pow

* Fix pow

* Remove some bounds

* More work

* Make grandpa work

* Make slots use `async_trait`

* Introduce `SharedData`

* Add test and fix bugs

* Switch to `SharedData`

* Make grandpa tests working

* More Babe work

* Make grandpa work

* Introduce `SharedData`

* Add test and fix bugs

* Switch to `SharedData`

* Make grandpa tests working

* More Babe work

* Make it async

* Fix fix

* Use `async_trait` in sc-consensus-slots

This makes the code a little bit easier to read and also expresses that
there can always only be one call at a time to `on_slot`.

* Make grandpa tests compile

* More Babe tests work

* Fix network test

* Start fixing service test

* Finish service-test

* Fix sc-consensus-aura

* Fix fix fix

* More fixes

* Make everything compile *yeah*

* Make manual-seal compile

* More fixes

* Start fixing Aura

* Fix Aura tests

* Fix Babe tests

* Make everything compile

* Move code around and switch to async_trait

* Fix Babe

* Docs docs docs

* Move to FRAME

* Fix fix fix

* Make everything compile

* Last cleanups

* Fix integration test

* Change slot usage of the timestamp

* We really need to switch to `impl-trait-for-tuples`

* Update primitives/inherents/src/lib.rs

Proof of work consensus for Substrate.

To use this engine, you can need to have a struct that implements PowAlgorithm. After that, pass an instance of the struct, along with other necessary client references to import_queue to setup the queue. Use the start_mine function for basic CPU mining.

The auxiliary storage for PoW engine only stores the total difficulty. For other storage requirements for particular PoW algorithm (such as the actual difficulty for each particular blocks), you can take a client reference in your PowAlgorithm implementation, and use a separate prefix for the auxiliary storage. It is also possible to just use the runtime as the storage, but it is not recommended as it won't work well with light clients.
