* don't modify inherent data on heavy block
* write up current thinking on block weight detection
* extract inherent inclusion check into its own function
* put heavy block check into runtime
* the `inclusion` inherent call is Operational, not Mandatory
This resolves a lot of the trickiness about this issue, because
we no longer need to override or supplant any existing proposer
logic; the existing logic should exhibit these behaviors:
- the `inclusion` inherent is prioritized over standard transactions
- but if it's too heavy, i.e. in case of runtime upgrade, it'll be
dropped in favor of that.
It is my belief that allowing the proposer to just not include
this data won't have any adverse effects: it's equivalent to replacing
them with empty versions of themselves, which the `ProvideInherent`
impl already does.

This reverts commit 38299d3c23e9efb5a354d8cfa658e62a5c8c7ddf.
* add backed candidate block weight assumption to configuration
* Limit backed candidates according to a candidate weight heuristic.
This approach replaces making the inclusion inherent non-mandatory.
It's still not ideal in that we have to configure a heuristic for
how much each backed candidate 'weighs', instead of directly
measuring it somehow.
This approach also never truncates the signed bitfields. The
rationale for that depends on some assumptions:
- processing the signed bitfields is cheap compared to the
backed candidates
- it is beneficial to the progress of the relay chain
to update the signed bitfields even if not all backed candidates
are updated
* simplify limit_backed_candidates and weight assumption
* don't trust the provisioner to fairly distribute candidates
* use saturating subtraction
* empty commit to restart ci
* use new mechanism for getting max block weight
* apply weight refunds to the inclusion inherent
This makes some assumptions about fundamental weights, which are
encapsulated as constants. From there, it lets Substrate know
what the actual computed weight of the inherent is.
* use a correct fixed weight for the inclusion inherent

* use dynamic inclusion weight so we reduce calculated weight when excluding candidates
* don't double-count this intrinsic's weight in the block weight
* add unit tests of fn limit_backed_candidates
* add tests that the inclusion inherent's weight correctly updates

* Add well_known_keys
* Reorder HrmpChannel and HostConfiguration members
* abridged versions and well known keys tests
* Add some comments
* Add a note on generation of the prefixes
and other magic values
* Recommend accessing the well known values through abridged structs
* Cont.: Implement the state root obtaining during inclusion
During inclusion now we obtain the storage root by passing it through
the inclusion_inherent.
* Fix tests
* Bump rococo spec version
* Reorder the parent header into the end
of the inclusion inherent.
When the parent header is in the beginning, it shifts the other two
fields, so that a previous version won't be able to decode that. If
we put the parent header in the end, the other two fields will stay
at their positions, thus make it possible to decode with the previous
version.
That allows us to perform upgrade of rococo runtime without needing of
simultanuous upgrade of nodes and runtime, or restart of the network.
* Squash a stray tab
* Don't initialize block when calling runtime APIs
* Adapt check_validation_outputs
We split the code path for the inclusion and for the commitments checking.
* Slap #[skip_initialize_block] on safe runtime APIs
That is, those that should not be affected by this attribute
* Make `Scheduled` not ephemeral
So that it is persisted in the storage and ready to be inspected
by the runtime APIs. This is in contrast to what was before, where we
would remove the storage entry and then rely on the scheduling performed
by `on_initialize` again.

i.e. move it from node specific primitives to global v1 primitives. This
will be needed when we share it later in the runtime inclusion module
* refactor acceptance checks in the inclusion module
factor out the common code to share it during the block inclusion and
for the forthcoming CheckValidationOutputs runtime api.
Also note that the acceptance criteria was updated to incorporate checks
that exist now in candidate-validation

Closes#1757.
We now have some evidence that the polkadot validator was producing
blocks after all; the reason the blocks_constructed metric was 0 was
that as a new metric it hadn't yet been incorporated into that
branch's codebase. See
https://github.com/paritytech/polkadot/issues/1757#issuecomment-700977602
As this PR is based on a newer `master` branch than the previous one,
that should hopefully no longer be an issue.
