Bastian Köcher 5eb816d7a6 Removal of execution strategies (#14387)
* Start

* More work!

* Moar

* More changes

* More fixes

* More worrk

* More fixes

* More fixes to make it compile

* Adds `NoOffchainStorage`

* Pass the extensions

* Small basti making small progress

* Fix merge errors and remove `ExecutionContext`

* Move registration of `ReadRuntimeVersionExt` to `ExecutionExtension`

Instead of registering `ReadRuntimeVersionExt` in `sp-state-machine` it is moved to
`ExecutionExtension` which provides the default extensions.

* Fix compilation

* Register the global extensions inside runtime api instance

* Fixes

* Fix `generate_initial_session_keys` by passing the keystore extension

* Fix the grandpa tests

* Fix more tests

* Fix more tests

* Don't set any heap pages if there isn't an override

* Fix small fallout

* FMT

* Fix tests

* More tests

* Offchain worker custom extensions

* More fixes

* Make offchain tx pool creation reusable

Introduces an `OffchainTransactionPoolFactory` for creating offchain transactions pools that can be
registered in the runtime externalities context. This factory will be required for a later pr to
make the creation of offchain transaction pools easier.

* Fixes

* Fixes

* Set offchain transaction pool in BABE before using it in the runtime

* Add the `offchain_tx_pool` to Grandpa as well

* Fix the nodes

* Print some error when using the old warnings

* Fix merge issues

* Fix compilation

* Rename `babe_link`

* Rename to `offchain_tx_pool_factory`

* Cleanup

* FMT

* Fix benchmark name

* Fix `try-runtime`

* Remove `--execution` CLI args

* Make clippy happy

* Forward bls functions

* Fix docs

* Update UI tests

* Update client/api/src/execution_extensions.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.

This library also comes with an async mining worker, which can be started via the start_mining_worker function. It returns a worker handle together with a future. The future must be pulled. Through the worker handle, you can pull the metadata needed to start the mining process via MiningWorker::metadata, and then do the actual mining on a standalone thread. Finally, when a seal is found, call MiningWorker::submit to build the block.

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.
