`ready_at` returns when we have processed the requested block. However,
on startup we already have processed the best block and there
are no transactions in the pool on startup anyway. So, we can set `updated_at`
to the best block on startup.

Besides that `ready_at` now returns early when there are no ready nor
any future transactions in the pool.

* Introduce a "dynamic" block size limit for proposing

This adds support for using a dynamic block size limit per call to
`propose`. This is required for Cumulus/Parachains to always use stay in
the limits of the maximum allowed PoV size.

As described in the docs, the block limit is only checked in the process
of pushing transactions. As we normally do some other operations in
`on_finalize`, it can happen that the block size still grows when there
is some proof being collected (as we do for parachains). This means,
that the given block limit needs to be rather conservative on the actual
value and should not be the upper limit.

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`.

* 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.

* Offgit feedback

* Cast cast cast

* 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.

* Make `on_slot` return the block with the post header

Before this pr `on_slot` returned the pre block. However this is wrong,
because adding some post digest changes the hash of the header. Thus,
we need to make sure to return the correct block that uses the post
header.

* 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

Currently we always use a boxed future everywhere anyway. This also
enables us to use a boxed `SlotWorker` (which is required for Cumulus).

* 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.
