In this PR, paras module emit runtime events on certain PVF pre-checking
related conditions.

Specifically, there are 3 new events in the paras module:

1. PvfCheckStarted
2. PvfCheckAccepted
3. PvfCheckRejected

All of those have identifiers for the parachain that triggered the PVF
pre-checking and the validation code that goes through the pre-checking.

The mechanics of those are as follows. Each time a new PVF is added, be
it due to onboarding or upgrading, the `PvfCheckStarted` will be
triggered. If another parachain triggers a pre-checking process for the
validation code which is already being pre-checked, another
`PvfCheckStarted` event will be triggered with the corresponding para
id.

When the PVF pre-checking voting for a PVF was finished, several
`PvfCheckAccepted/Rejected` events will be triggered: one for each para id that
was subscribed to this check (i.e. was a "cause" for it).

If the PVF pre-checking is disabled, then one can still expect these
events to be fired. Since insta PVF approval is syncronous, the
`PvfCheckStarted` will be followed by the `PvfCheckAccepted` with the
same validation code and para id.

If somebody is interested in following validation code changes for a PVF
of a parachain, they would need to subscribe to those events. I did not
supply the topics for the events, since I am not sure if that's needed
or will be used, but they can be added later if needed.

This is only a module structure change: the tests module was promoted to
have its own file.

As was brought up in [here][og], we have some copy&paste comments. I
fixed them and also took liberty of fixing some other places.
Specifically, those that say "module" instead of contemporary "pallet".

[og]:
https://github.com/paritytech/polkadot/pull/4603#discussion_r776971291

Closes #3971

Read the linked issue.

Apart from that, this addresses the concern raised in this [comment] by
just adding a test. I couldn't find a clean way to reconcile a block
number delay with a PVF voting TTL, so I just resorted to rely on the
test. Should be fine for now.

[comment]: https://github.com/paritytech/polkadot/pull/4457#discussion_r770517562

This just renames a member of `HostConfiguration` from
validation_upgrade_frequency to -//-_cooldown.

As was already pointed out in #4460 the existing name is a misnomer, the
member actually represents a minimum time period between upgrades, which
is neatly expressed by a word cooldown.

I've been planning this rename already for some time and the term is
already used in paras module:

https://github.com/paritytech/polkadot/blob/1394b70d/runtime/parachains/src/paras.rs#L1568-L1574

* paras: add governance control dispatchables

Adds a couple of functions for governance control for the paras module
in the anticipation of PVF pre-checking enabling.

Specifically, this commit adds a function for pre-registering a PVF that
governance trusts enough. This function will come in handy in case there
is a parachain that does not follow the GoAhead signal. That is, does
not include https://github.com/paritytech/cumulus/pull/517.

This may be not an exhaustive list of the functions that may come in
handy. Any suggestions to add more are welcome.

This is the first step to close
https://github.com/paritytech/polkadot/issues/4524

Closes #4248

Impose additional constraint on configuration consistency:
`validation_upgrade_delay` should not be less than or equal to 1.

See the original issue for more details.

Setting zero as weight may be a source of problems.

The problem is, a rogue validator can shove a lot of duplicated votes
and thus fill a block with work that may well exceed the weight limit.

As was suggested by Alexander Popiak [here][comment], this commit
checks the consistency of the configuration.

[comment]:
https://github.com/paritytech/polkadot/pull/4420#discussion_r764796519

This commit refactors the consistency checks. Instead of each individual
setter performs its checks locally, we delegate those checks to the
already existing function `check_consistency`. This removes duplication
and simplifies the logic.

A motivating example of this one is the next PR in the stack that will
introduce a check for a field, which validity depends on the validity of
other two fields. Without this refactoring we will have to place a check
not only to the field in question, but also to the other two fields so
that if they are changed they do not violate consistency criteria. It's
easy to imagine how this can go unwieldy with the number of checks.

This also adds a test that verifies that the default chain spec host
configuration is consistent.

* parachains: Fix configuration module

Closes #4529
Closes #4533

I figured that trying to avoid updates does not really worth it to keep.
This is because we seem to not update the configuration often and when
we do we approach this carefully. Thus possibility of a redundant update
is really negligable. At the same time, if such a redundant update does
happen then the effects of that are really small: just some wasted
storage interactions.

On the other hand, making it work was a little bit annoying. With the
proper fix for the pending updates this would be even more annoying
since now we would have to add combinatorically more cases to test this.

So I figured that I will just scrap that and simplify the code.

* pvf-precheck: Integrate PVF pre-checking into paras module

Closes #4009

This is the most of the runtime-side change needed for #3211.

Here is how it works.

The PVF pre-checking can be triggered either by an upgrade or by
onboarding (i.e. calling `schedule_para_initialize`). The PVF
pre-checking process is identified by the PVF code hash that is being
voted on. If there is already PVF pre-checking process running, then no
new PVF pre-checking process will be started. Instead, we just subscribe
to the existing one.

If there is no PVF pre-checking process running but the PVF code hash
was already saved in the storage, that necessarily means (I invite the
reviewers to double-check this invariant) that the PVF already passed
pre-checking. This is equivalent to instant approving of the PVF.

The pre-checking process can be concluded either by obtaining a
supermajority or if it expires.

Each validator checks the list of PVFs available for voting. The vote is
binary, i.e. accept or reject a given PVF. As soon as the supermajority
of votes are collected for one of the sides of the vote, the voting is
concluded in that direction and the effects of the voting are enacted.

Only validators from the active set can participate in the vote. The set
of active validators can change each session. That's why we reset the
votes each session. A voting that observed a certain number of sessions
will be rejected.

The effects of the PVF accepting depend on the operations requested it:

1. All onboardings subscribed to the approved PVF pre-checking process will
get scheduled and after passing 2 session boundaries they will be onboarded.
2. All upgrades subscribed to the approved PVF pre-checking process will
get scheduled very similarly to the existing process. Upgrades with
pre-checking are really the same process that is just delayed by the
time required for pre-checking voting. In case of instant approval the
mechanism is exactly the same. This is important from parachains
compatibility standpoint since following the delayed upgrade requires
the parachain to implement
https://github.com/paritytech/cumulus/pull/517.

In case, PVF pre-checking process was concluded with rejection, then all
the requesting operations get cancelled. For onboarding it means it gets
without movement: the lifecycle of such parachain is terminated on the
`Onboarding` state and after rejection the lifecycle is none. That in
turn means that the caller can attempt registering the parachain once
more. For upgrading it means that the upgrade process is aborted: that
flashes go-ahead signal with `Abort` flag.

Rejection leads to removing the allegedly bad validation code from the
chain storage. Among other things, this implies that the operation can
be re-requested. That allows for retrying an operation in case there was
some bug. At the same time it does not look as a DoS vector due to the
caching performed by the nodes.

PVF pre-checking can be enabled and disabled. Initially, according to
the changes in #4420, this mechanism is disabled. Triggering the PVF
pre-checking when it is disabled just means that we insta approve the
requesting operation. This should lead to the behavior being unchanged.

Follow-ups:

- expose runtime APIs
