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

* 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

* Make the constructor private

* Happy new year

Updates the copyright years and fixes wrong license headers.

This prevents nodes from executing the same block 2 times.

* 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.

* Revalidate transactions only on latest best block

* Seperate out the complexity in ServiceBuilder::build_common into seperate functions

* Fix line widths

* Move some functions to their respective crates

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)

`SpawnBlocking` that exposes this requirement to the outside.
