The timestamp inherent type was up to now just a simple `u64`. This
worked, but doesn't give you that much guarantees at compile time about
the type. This pr changes that by converting this type to a unit type
wrapper, similar to what we have done for `Slot`.

This is required for some future pr that touches quite a lot of the
inherents stuff :)

Besides this unit wrapper type, this pr also moves the `OnTimestampSet`
trait to `frame_support::traits`.

* Ensure we spawn the block import worker as an essential task

This pr ensures that we spawn the block import worker as an essential
task. This is quite important as we need to bring down the node when the
block import is done. Besides that it adds some debug output to the
block import worker.

* Don't be stupid :D

* Ahh

* Work work work

* Fix all the compilation errors

* update cargo.toml

* use 2.0 in mmmr

* Introduce a `Slot` type

Instead of having some type definition that only was used in half of the
code or directly using `u64`, this adds a new unit type wrapper `Slot`.
This makes it especially easy for the outside api to know what type is
expected/returned.

* Change epoch duratioC

* rename all instances of slot number to slot

* client/finality-grandpa: Use `Arc<dyn CryptoStore>` instead of SyncXXX

Instead of using `SyncCryptoStorePtr` within `client/finality-grandpa`,
which is a type alias for `Arc<dyn SyncCryptoStore>`, use `Arc<dyn
CryptoStore>`. Benefits are:

1. No additional mental overhead of a `SyncCryptoStorePtr`.

2. Ability for new code to use the asynchronous methods of `CryptoStore`
instead of the synchronous `SyncCryptoStore` methods within
`client/finality-granpa` without the need for larger refactorings.

Note: This commit uses `Arc<dyn CryptoStore>` instead of
`CryptoStorePtr`, as I find the type signature more descriptive. This is
subjective and in no way required.

* Fix line widths

* Move some functions to their respective crates

* Bump jsonrpc pubsub, core, http, and ws

Right now these are the packages which _need_ to be updated
so I can just the latest `jsonrpc-pubsub` code. Once a release
it cut upstream the rest of the dependencies should be updated
as well.

* Use jsonrpc-pubsub's SubscriptionManager

This places sc-rpc-api::Subscriptions

* Bump jsonrpc-core outside of sc-rpc-*

* Update client/rpc tests

Right now one of the `author` tests is failing, I
need to think a bit about how best to fix it.

* Remove Subscriptions manager

There's no need for this implementation since we're
using the one from `jsonrpc-pubsub` now

* Fix author RPC test

This test used to check for a numerial subscription ID,
whereas now it uses a string based ID which is the default
provided by `jsonrpc-pubsub`'s subscription manager.

* Remove unused NumericIdProvider

* Add missing bracket

Removed one too many with that last one, lol

* Bump `jsonrpc` to v14.2

There's an exception though. `jsonrpc-derive` cannot be bumped
past v14.0.5 just yet since it has a dependency on `quote` pinned
to v1.0.1. This means that at the moment it won't build on Substrate
since it's using v1.0.3.

* Track `jsonrpc-derive` master branch

* Bump `quote` version to v1.0.6

* Bump `jsonrpc-derive` to v14.2.1

This includes support for `quote` v1.0.6

* Use exact version for jsonrpc crates

Doing this to make sure any updates in jsonrpc don't
accidently trickle down to Polkadot.

Co-authored-by: André Silva <[email protected]>

The `tree_route` generated by the import notification is only from the
old best block to the new best parent. This means, it does not contain
the new best block in `enacted()`. We need to prune the transactions of
the new best block "manually" to fix this bug.

Besides that, this pr also changed the `id` parameter of the `NewBlock`
chain event to `hash`. The hash of a block is unique in contrast to the
block number. (Block id can either be number or hash)

A proposer must be created per new round, so it makes sense to have the
proposer consume its own reference.
