Removal of verbatim duplication of BABE's `Epoch` struct in the client.

I think is better to have one single definition and wrap the primitive
`Epoch` in a newtype (required because we need to implement the `Epoch`
trait).

Make Preimage pallet use Consideration instead of handling deposits
directly.

Other half of paritytech/substrate#13666.
Depends/based on #1361.

Script for the lazy migration that should be run manually once:

## TODO

When adding this pallet to the [Coretime

dependency results in conflicting implementations (rustc error below).

This PR adds test case for successful `send_xcm` for `XcmpQueue`
according to the opened HRMP channel to the sibling parachain.

Submit the outstanding PRs from the old repos(these were already
reviewed and approved before the repo rorg, but not yet submitted):
Main PR: https://github.com/paritytech/substrate/pull/14014
Companion PRs: https://github.com/paritytech/polkadot/pull/7134,
https://github.com/paritytech/cumulus/pull/2489

The changes in the PR:
1. ChainSync currently calls into the block request handler directly.
Instead, move the block request handler behind a trait. This allows new
protocols to be plugged into ChainSync.
2. BuildNetworkParams is changed so that custom relay protocol
implementations can be (optionally) passed in during network creation
time. If custom protocol is not specified, it defaults to the existing
block handler
3. BlockServer and BlockDownloader traits are introduced for the
protocol implementation. The existing block handler has been changed to
implement these traits
4. Other changes:
[X] Make TxHash serializable. This is needed for exchanging the
serialized hash in the relay protocol messages
[X] Clean up types no longer used(OpaqueBlockRequest,
OpaqueBlockResponse)

Upgrades to docify v0.2.3, which includes a fix for

Adding extra tests for inclusion pruning. Primarily focusing on various
cases surrounding candidates included in different forks (with different
relay parents).

All cases fall into a few buckets based on 3 degrees of freedom - number
of candidates, number of blocks (height), number of forks + extra case
for pruning multiple heights at once.

Added small tweak to the original pruning function to disregard stale
candidate duplicates which should keep the same behaviour.

Enable `runtime-benchmarks` feature for `parachain-common` and
`cumulus-primitives-utility` crates' dependencies.

After adding `runtime-benchmarks = []` under `features` category in

## Summary

Implementations of `SendXcm`'s `validate` should not consume `dest`
and/or `msg` parameters in case of `NotApplicable` error.
This commit aligns expected behavior for `UnpaidRemoteExporter` and
`SovereignPaidRemoteExporter`.

## Testing

Added `remote_exporters_does_not_consume_dest_or_msg_on_not_applicable`
test which checks two possible cases:
- `dest` is local
- no configured exporter for `dest`

We want to be able to (re)set BEEFY genesis in order to (re)start BEEFY
consensus on chains which didn't run it since genesis.

Closes https://github.com/paritytech/polkadot-sdk/issues/158

In our last FRAME call it was discussed that a likely solution to the ED
imbalances is lazily fixing the pools as they are interacted with.

So, we should add some tiny tolerance to the try-state checks so next
time there's an ED change they don't start failing until they've all
been interacted with.

### Update 12 Sept

Rather than adding tolerance, have replaced the `ensure` with a warning.

`VersionedMigration` has become somewhat widely used for handling
version bumps in migrations the last few months.

It is currently behind the `experimental` feature flag, requiring every
pallet that writes a new migration with version bumps to set up the
`experimental` flag in their own Cargo.tomls, and also for every runtime
using these pallets to explicitly enable the `experimental` flag for
each pallet.

This is becoming quite verbose, and I can only see the number of pallets
requiring the experimental flag increasing for no other reason than
using what has become a commonly used feature.

Additionally, I'm writing migration docs and would like to avoid
stepping through how to use the `experimental` feature to get
`VersionedMigration` working.

Since the feature has been used in production for some time now without
any reported issues, is becoming commonly used and ready to advertise in
docs, I feel this is a good time to make it non-experimental.

# Description

Each time the validator set changes, BEEFY validator keys are converted
to ETH addresses and merkelised into a `keyset_commitment` to be used by
light clients.

This commit downgrades `error` to `debug` when individual conversions
from BEEFY keys to ETH addresses fail, and adds cumulative check that
reports total number of failed conversions, if any, on `error`
log-level.

When `process_file` is run by `xargs`, it is executed inside a new shell
without access to variables defined outside of its scope.

This resulted in `script_content` being an empty string.

By exporting `script_content` prior to running `xargs` it is available
inside the new shells.

Fixes #116 

Start function wasn't allowed in a contract. Now it is allowed and is
being run.

It was disallowed because it is not used by Rust and supporting it made
the code more complex. However, not running the start function violates
the wasm standard. This makes life harder for some languages (see linked
ticket).

This PR addresses multiple issues pending:

* [x] Update orchestra to the recent version and test how the node
performs
* [x] Add some useful metrics for outbound network bridge
* [x] Try to send incoming network requests to all subsystems without
blocking on some particular subsystem in that loop
* [x] Fix all incompatibilities between orchestra and polkadot code
(e.g. malus node)

Closes #583

After the separation of PVF worker binaries, dedicated puppet workers
are not needed for tests anymore. The production workers can be used
instead, avoiding some code duplication and decreasing complexity.

The changes also make it possible to further refactor the code to
isolate workers completely.
