Test started failing after
https://github.com/paritytech/polkadot-sdk/commit/66051adb619d2119771920218e2de75fa037d7e8
which enabled approval coalescing, that was expected to happen because
the test required an polkadot_parachain_approval_checking_finality_lag
of 0, which can't happen with max_approval_coalesce_count greater than 1
because we always delay the approval for no_show_duration_ticks/2 in
case we can coalesce it with other approvals.
So relax a bit the restrictions, since we don't actually care that the
lags are 0, but the fact the finalities are progressing and are not
stuck.

The metric records the current protocol_version of the validator that
just connected with the peer_map.len(), which contains all peers that
connected, that has the effect the metric will be wrong since it won't
tell us how many peers we have connected per version because it will
always record the total number of peers
Fix this by counting by version inside peer_map, additionally because
that might be a bit heavier than len(), publish it only on-active
leaves.

# Description
Since the binary split additional syscalls are getting blocked in
relation to the workers.
With the hardened systemd file it shows the following warning:
```
Cannot fully enable landlock, a Linux kernel security feature. Running validation of malicious PVF code has a higher risk of compromising this machine. Consider upgrading the kernel version for maximum security. status=Ok(NotEnforced) abi=1
```
For it to work we need to allow additionally:
- mount
- umount2
- pivot_root
and set `RestrictNamespaces=false`
Added new line `SystemCallFilter=pivot_root` because otherwise it would
get blocked by ~\@\privileged

This PR adds a new extrinsic `Call::restore_ledger ` gated by
`StakingAdmin` origin that restores a corrupted staking ledger. This
extrinsic will be used to recover ledgers that were affected by the
issue discussed in
https://github.com/paritytech/polkadot-sdk/issues/3245.
The extrinsic will re-write the storage items associated with a stash
account provided as input parameter. The data used to reset the ledger
can be either i) fetched on-chain or ii) partially/totally set by the
input parameters of the call.
In order to use on-chain data to restore the staking locks, we need a
way to read the current lock in the balances pallet. This PR adds a
`InspectLockableCurrency` trait and implements it in the pallet
balances. An alternative would be to tightly couple staking with the
pallet balances but that's inelegant (an example of how it would look
like in [this
branch](https://github.com/paritytech/polkadot-sdk/tree/gpestana/ledger-badstate-clean_tightly)).
More details on the type of corruptions and corresponding fixes
https://hackmd.io/DLb5jEYWSmmvqXC9ae4yRg?view#/
We verified that the `Call::restore_ledger` does fix all current
corrupted ledgers in Polkadot and Kusama. You can verify it here
https://hackmd.io/v-XNrEoGRpe7APR-EZGhOA.
**Changes introduced**
- Adds `Call::restore_ledger ` extrinsic to recover a corrupted ledger;
- Adds trait `frame_support::traits::currency::InspectLockableCurrency`
to allow external pallets to read current locks given an account and
lock ID;
- Implements the `InspectLockableCurrency` in the pallet-balances.
- Adds staking locks try-runtime checks
(https://github.com/paritytech/polkadot-sdk/issues/3751)
**Todo**
- [x] benchmark `Call::restore_ledger`
- [x] throughout testing of all ledger recovering cases
- [x] consider adding the staking locks try-runtime checks to this PR
(https://github.com/paritytech/polkadot-sdk/issues/3751)

Fixes#3826.
The docs on the `candidates` field of `BlockEntry` were incorrectly
stating that they are sorted by core index. The (incorrect) optimization
was introduced in #3747 based on this assumption. The actual ordering is
based on `CandidateIncluded` events ordering in the runtime. We revert
this optimization here.

The PR provides API for obtaining:
- the weight required to execute an XCM message,
- a list of acceptable `AssetId`s for message execution payment,
- the cost of the weight in the specified acceptable `AssetId`.
It is meant to address an issue where one has to guess how much fee to
pay for execution. Also, at the moment, a client has to guess which
assets are acceptable for fee execution payment.
See the related issue
https://github.com/paritytech/polkadot-sdk/issues/690.
With this API, a client is supposed to query the list of the supported
asset IDs (in the XCM version format the client understands), weigh the
XCM program the client wants to execute and convert the weight into one
of the acceptable assets. Note that the client is supposed to know what
program will be executed on what chains. However, having a small
companion JS library for the pallet-xcm and xtokens should be enough to
determine what XCM programs will be executed and where (since these
pallets compose a known small set of programs).
```Rust
pub trait XcmPaymentApi<Call>
where
Call: Codec,
{
/// Returns a list of acceptable payment assets.
///
/// # Arguments
///
/// * `xcm_version`: Version.
fn query_acceptable_payment_assets(xcm_version: Version) -> Result<Vec<VersionedAssetId>, Error>;
/// Returns a weight needed to execute a XCM.
///
/// # Arguments
///
/// * `message`: `VersionedXcm`.
fn query_xcm_weight(message: VersionedXcm<Call>) -> Result<Weight, Error>;
/// Converts a weight into a fee for the specified `AssetId`.
///
/// # Arguments
///
/// * `weight`: convertible `Weight`.
/// * `asset`: `VersionedAssetId`.
fn query_weight_to_asset_fee(weight: Weight, asset: VersionedAssetId) -> Result<u128, Error>;
/// Get delivery fees for sending a specific `message` to a `destination`.
/// These always come in a specific asset, defined by the chain.
///
/// # Arguments
/// * `message`: The message that'll be sent, necessary because most delivery fees are based on the
/// size of the message.
/// * `destination`: The destination to send the message to. Different destinations may use
/// different senders that charge different fees.
fn query_delivery_fees(destination: VersionedLocation, message: VersionedXcm<()>) -> Result<VersionedAssets, Error>;
}

Let me know if this structure is adequate.
**Note:** The usage of the words `Merkle`, `Merkelize`, `Merklization`,
`Merkelization`, `Merkleization`, is somewhat inconsistent but I left it
as it is.
~~**Note:** In some places the term `Receival` is used to refer to
message reception, IMO `Reception` is the correct word here, but I left
it as it is.~~
~~**Note:** In some places the term `Overlayed` is used instead of the
more acceptable version `Overlaid` but I also left it as it is.~~
~~**Note:** In some places the term `Applyable` is used instead of the
correct version `Applicable` but I also left it as it is.~~
**Note:** Some usage of British vs American english e.g. `judgement` vs
`judgment`, `initialise` vs `initialize`, `optimise` vs `optimize` etc.
are both present in different places, but I suppose that's
understandable given the number of contributors.
~~**Note:** There is a spelling mistake in `.github/CODEOWNERS` but it
triggers errors in CI when I make changes to it, so I left it as it

The results for the `availability-distribution` subsystem are volatile,

This PR doesn't contain any functional changes.
The PR moves specific bridged chain definitions from
`bridges/primitives` to `bridges/chains` folder in order to facilitate
the migration of the `parity-bridges-repo` into `polkadot-sdk` as
discussed in https://hackmd.io/LprWjZ0bQXKpFeveYHIRXw?view
Apart from this it also includes some cosmetic changes to some
`Cargo.toml` files as a result of running `diener workspacify`.
Currently `transfer_assets` from pallet-xcm covers 4 main different
transfer types:
- `localReserve`
- `DestinationReserve`
- `Teleport`
- `RemoteReserve`
For the first three, the local execution and the remote message sending
are separated, and fees are deducted in pallet-xcm itself:
https://github.com/paritytech/polkadot-sdk/blob/3410dfb3929462da88be2da813f121d8b1cf46b3/polkadot/xcm/pallet-xcm/src/lib.rs#L1758.
For the 4th case `RemoteReserve`, pallet-xcm is still relying on the
xcm-executor itself to send the message (through the
`initiateReserveWithdraw` instruction). In this case, if delivery fees
need to be charged, it is not possible to do so because the
`jit_withdraw` mode has not being set.
This PR proposes to still use the `initiateReserveWithdraw` but
prepending a `setFeesMode { jit_withdraw: true }` to make sure delivery
fees can be paid.
A test-case is also added to present the aforementioned case

[#2512](https://github.com/paritytech/polkadot-sdk/issues/2512), it
seems that some ecosystem teams are using these networks to set up their
staging environments and test certain use cases, some of them involving
sending XCMs from the relay with origins not allowed in the current
configuration.
This change reverts the configuration of `SendXcmOrigin`.

Small refactoring to reduce the algorithmic complexity of the initial
message distribution in approval voting after a sync from O(n_candidates
^ 2) to O(n_candidates).
We witnessed really poor performance on Rococo, where we ended up with
50 on-demand cores. This was due to the fact that for each core the full
queue was processed. With this change full queue processing will happen
way less often (most of the time complexity is O(1) or O(log(n))) and if
it happens then only for one core (in expectation).
Also spot price is now updated before each order to ensure economic back
pressure.
TODO:
- [x] Implement
- [x] Basic tests
- [x] Add more tests (see todos)
- [x] Run benchmark to confirm better performance, first results suggest
> 100x faster.
- [x] Write migrations
- [x] Bump scale-info version and remove patch in Cargo.toml
- [x] Write PR docs: on-demand performance improved, more on-demand
cores are now non problematic anymore. If need by also the max queue
size can be increased again. (Maybe not to 10k)
Optional: Performance can be improved even more, if we called
`pop_assignment_for_core()`, before calling `report_processed` (Avoid
needless affinity drops). The effect gets smaller the larger the claim
queue and I would only go for it, if it does not add complexity to the
scheduler.

The PR adds two things:
1. Runtime API exposing the whole claim queue
2. Consumes the API in `collation-generation` to fetch the next

Introduces `CryptoBytes` type defined as:
```rust
pub struct CryptoBytes<const N: usize, Tag = ()>(pub [u8; N], PhantomData<fn() -> Tag>);
```
The type implements a bunch of methods and traits which are typically
expected from a byte array newtype
(NOTE: some of the methods and trait implementations IMO are a bit
redundant, but I decided to maintain them all to not change too much
stuff in this PR)
It also introduces two (generic) typical consumers of `CryptoBytes`:
`PublicBytes` and `SignatureBytes`.
```rust
pub struct PublicTag;
pub PublicBytes<const N: usize, CryptoTag> = CryptoBytes<N, (PublicTag, CryptoTag)>;
pub struct SignatureTag;
pub SignatureBytes<const N: usize, CryptoTag> = CryptoBytes<N, (SignatureTag, CryptoTag)>;
```
Both of them use a tag to differentiate the two types at a higher level.
Downstream specializations will further specialize using a dedicated
crypto tag. For example in ECDSA:
```rust
pub struct EcdsaTag;
pub type Public = PublicBytes<PUBLIC_KEY_SERIALIZED_SIZE, EcdsaTag>;
pub type Signature = PublicBytes<PUBLIC_KEY_SERIALIZED_SIZE, EcdsaTag>;
```
Overall we have a cleaner and most importantly **consistent** code for
all the types involved
All these details are opaque to the end user which can use `Public` and
`Signature` for the cryptos as before
On top of #3302.
We want the validators to upgrade first before we add changes to the
collation side to send the new variants, which is why this part is
extracted into a separate PR.
The detection of when to send the parent head is based on the core
assignments at the relay parent of the candidate. We probably want to
make it more flexible in the future, but for now, it will work for a
simple use case when a para always has multiple cores assigned to it.

Currently the xcm-executor returns an `Unimplemented` error if it
receives any HRMP-related instruction.
What I propose here, which is what we are currently doing in our forked
executor at polimec, is to introduce a trait implemented by the executor
which will handle those instructions.
This way, if parachains want to keep the default behavior, they just use
`()` and it will return unimplemented, but they can also implement their
own logic to establish HRMP channels with other chains in an automated
fashion, without requiring to go through governance.
Our implementation is mentioned in the [polkadot HRMP
docs](https://arc.net/l/quote/hduiivbu), and it was suggested to us to
submit a PR to add these changes to polkadot-sdk.

Fixes#3128.
This introduces a new variant for the collation response from the
collator that includes the parent head data. For now, collators won't
send this new variant. We'll need to change the collator side of the
collator protocol to detect all the cores assigned to a para and send
the parent head data in the case when it's more than 1 core.
