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`.

Currently we wrap every `GenesisConfig` field in an `Option`, while
we require `Default` being implemented for all pallet genesisconfigs.
Passing `None` also results in the genesis not being initialized, which
is a bug as seen from the perspective of a pallet developer?

This pr changes the fields of the `GenesisConfig` to non `Option` types.

* implement

* make default pre/post_upgrade

* simplify Cargo.toml

* revert removal of outdated/private links

* link in pallet-mmr

That was actually a bad idea by me, because it should essentially be the
same as block.header.

* Init `RuntimeLogger` automatically for each runtime api call

This pr change the runtime api in such a way to always and automatically
enable the `RuntimeLogger`. This enables the user to use `log` or
`tracing` from inside the runtime to create log messages. As logging
introduces some extra code and especially increases the size of the wasm
blob. It is advised to disable all logging completely with
`sp-api/disable-logging` when doing the wasm builds for the on-chain
wasm runtime.

Besides these changes, the pr also brings most of the logging found in
frame to the same format "runtime::*".
