* Introduce new concept of "slot portion for proposing"

Currently when building a block we actually give the proposer all of the
time in the slot, while this is wrong. The slot is actually split in at
least two phases proposing and propagation or in the polkadot case into
three phases validating pov's, proposing and propagation. As we don't
want to bring that much polkadot concepts into Substrate, we only
support splitting the slot into proposing and propagation. The portion
can now be passed as parameter to AuRa and BABE to configure this value.
However, this slot portion for propagation doesn't mean that the
proposer can not go over this limit. When we miss slots we still apply
the lenience factor to increase the proposing time, so that we have
enough time to build a heavy block.

Besides all what was said above, this is especially required for
parachains. Parachains have a much more constraint proposing window.
Currently the slot duration is at minimum 12 seconds, but we only have
around 500ms for proposing. So, this slot portion for proposing is
really required to make it working without hacks.

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.

* AuRa improvements

Hot and fresh AuRa improvements. This pr does the following:

- Move code belonging to the import queue etc to import_queue.rs
- Introduce `ImportQueueParams` and `StartAuraParams` structs to make
it more easier to understand what parameters we pass to AuRa.
- Introduce `CheckForEquivocation` to tell AuRa if it should check for
equivocation on block import. This is required for parachains, because
they are allowed to equivocate when they build two blocks for the same
slot, but for different relay chain parents.

We were using the wrong syntax and that will be dropped with Rust 2021.
The compiler already starts to hint the wrong syntax with warnings. So,
we fix this here.

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

* contracts: Use unstable sort for topics

* Add warning about non-determinism

* 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::*".
