- Removal of Arkworks unit tests. These tests were just testing the
arkworks upstream implementation which should be assumed correct. This
is not the place to test well known dependencies.
- Removal of some over-engineering. We just store the calls to Arkworks
in one file. Per-curve sources are not required.
- Docs formatting

I also took the opportunity to bump the `bandersnatch-vrfs` crate
revision internally providing some new shiny stuff.

The runtime code of a parachain can be replaced on the relay-chain via:

[cumulus]:
[enact_authorized_upgrade](https://github.com/paritytech/polkadot-sdk/blob/1a38d6d6/cumulus/pallets/parachain-system/src/lib.rs#L661);
this is used for a runtime upgrade when a parachain is not bricked.

[polkadot] (these are used when a parachain is bricked):
-
[force_set_current_code](https://github.com/paritytech/polkadot-sdk/blob/1a38d6d6/polkadot/runtime/parachains/src/paras/mod.rs#L823):
immediately changes the runtime code of a given para without a pvf check
(root).
-
[force_schedule_code_upgrade](https://github.com/paritytech/polkadot-sdk/blob/1a38d6d6/polkadot/runtime/parachains/src/paras/mod.rs#L864):
schedules a change to the runtime code of a given para including a pvf
check of the new code (root).
-
[schedule_code_upgrade](https://github.com/paritytech/polkadot-sdk/blob/1a38d6d6/polkadot/runtime/common/src/paras_registrar.rs#L395):
schedules a change to the runtime code of a given para including a pvf
check of the new code. Besides root, the parachain or parachain manager
can call this extrinsic given that the parachain is unlocked.

Polkadot signals a parachain to be ready for a runtime upgrade through
the
[GoAhead](https://github.com/paritytech/polkadot-sdk/blob/e4949344

/polkadot/primitives/src/v5/mod.rs#L1229)
signal.

When in cumulus `enact_authorized_upgrade` is executed, the same
underlying helper function of `force_schedule_code_upgrade` &
`schedule_code_upgrade`:
[schedule_code_upgrade](https://github.com/paritytech/polkadot/blob/09b61286da11921a3dda0a8e4015ceb9ef9cffca/runtime/parachains/src/paras/mod.rs#L1778),
is called on the relay-chain, which sets the `GoAhead` signal (if the
pvf is accepted).

If Cumulus receives the `GoAhead` signal from polkadot without having
the `PendingValidationCode` ready, it will panic
([ref](https://github.com/paritytech/polkadot/pull/7412)). For
`enact_authorized_upgrade` we know for sure the `PendingValidationCode`
is set. On the contrary, for `force_schedule_code_upgrade` &
`schedule_code_upgrade` this is not the case.

This PR includes a flag such that the `GoAhead` signal will only be set
when a runtime upgrade is enacted by the parachain
(`enact_authorized_upgrade`).

This PR refactors the staking ledger logic to encapsulate all reads and
mutations of `Ledger`, `Bonded`, `Payee` and stake locks within the
`StakingLedger` struct implementation.

With these changes, all the reads and mutations to the `Ledger`, `Payee`
and `Bonded` storage map should be done through the methods exposed by
StakingLedger to ensure the data and lock consistency of the operations.
The new introduced methods that mutate and read Ledger are:

- `ledger.update()`: inserts/updates a staking ledger in storage;
updates staking locks accordingly (and ledger.bond(), which is synthatic
sugar for ledger.update())
- `ledger.kill()`: removes all Bonded and StakingLedger related data for
a given ledger; updates staking locks accordingly;
`StakingLedger::get(account)`: queries both the `Bonded` and `Ledger`
storages and returns a `Option<StakingLedger>`. The pallet impl exposes
fn ledger(account) as synthatic sugar for `StakingLedger::get(account)`.

Retrieving a ledger with `StakingLedger::get()` can be done by providing
either a stash or controller account. The input must be wrapped in a
`StakingAccount` variant (Stash or Controller) which is treated
accordingly. This simplifies the caller API but will eventually be
deprecated once we completely get rid of the controller account in
staking. However, this refactor will help with the work necessary when
completely removing the controller.

Other goals:

- No logical changes have been introduced in this PR;
- No breaking changes or updates in wallets required;
- No new storage items or need to perform storage migrations;
- Centralise the changes to bonds and ledger updates to simplify the
OnStakingUpdate updates to the target list (related to
https://github.com/paritytech/polkadot-sdk/issues/443)

Note: it would be great to prevent or at least raise a warning if
`Ledger<T>`, `Payee<T>` and `Bonded<T>` storage types are accessed
outside the `StakingLedger` implementation. This PR should not get
blocked by that feature, but there's a tracking issue here
https://github.com/paritytech/polkadot-sdk/issues/149

Related and step towards
https://github.com/paritytech/polkadot-sdk/issues/443

BEEFY needs two cryptographic keys at the same time. Validators should
sign BEEFY payload using both ECDSA and BLS key. The network will gossip
a payload which contains a valid ECDSA key. The prover nodes aggregate
the BLS keys if aggregation fails to verifies the validator which
provided a valid ECDSA signature but an invalid BLS signature is subject
to slashing.

As such BEEFY session should be initiated with both key. Currently there
is no straight forward way of doing so, beside having a session with
RuntimeApp corresponding to a crypto scheme contains both keys.

This pull request implement a generic paired_crypto scheme as well as
implementing it for (ECDSA, BLS) pair.

Pros:
* simpler interface, just functions:
`create_runtime_from_artifact_bytes()` and `execute_artifact()`

Cons:
* extra overhead of constructing executor semantics each time

I could make it a combination of
* `create_runtime_config(params)` (such that we could clone the
constructed semantics)
* `create_runtime(blob, config)`
* `execute_artifact(blob, config, params)`

Not sure if it's worth it though.

Part of #171

- Remove cached messages used for deduplication in `GossipValidator`
since they're already deduplicated in upper layer `NetworkGossip`.
- Add cache for "justified rounds" to quickly discard any further (even
if potentially different) justifications at the gossip level, once a
valid one (for a respective round) is submitted to the worker.
- Add short-circuit in worker `finalize()` method to not attempt to
finalize same block multiple times (for example when we get
justifications for same block from multiple components like
block-import, gossip or on-demand).
- Change a test which had A LOT of latency in syncing blocks for some
weird reason and would only run after ~150seconds. It now runs
instantly.

### Todo

- [x]  UI Test

# Description

In a couple of cases, there were links pointing to the w3f github pages
domain. In other instances, there were links pointing to the old
polkadot repo's github pages. Both of these are now pointing to the
relevant links in
https://paritytech.github.io/polkadot-sdk/book/index.html.

These changes were made specifically because the w3f github pages
returns a 404, and while fixing the links, the old polkadot repo links
were touched up as well even if they do redirect properly.

This shouldn't affect anything as these are documentation link changes
only.

# Desription

## Summary 

This PR introduces several nits and tweaks to xcm emulator tests for
system parachains.

## Explanation

**Deduplicate `XcmPallet::send(` with root origin code**
- Introduced `send_transact_to_parachain` which could be easily reuse
for scenarios like _governance call from relay chain to parachain_.

**Refactor `send_transact_sudo_from_relay_to_system_para_works`**
- Test covered just one use-case which was moved to the
`do_force_create_asset_from_relay_to_system_para`, so now we can extend
this test with more _governance-like_ senarios.
- Renamed to
`send_transact_as_superuser_from_relay_to_system_para_works`.

**Remove `send_transact_native_from_relay_to_system_para_fails` test**
- This test and/or description is kind of misleading, because system
paras support Native from relay chain by `RelayChainAsNative` with
correct xcm origin.
- It tested only sending on relay chain which should go directly to the
relay chain unit-tests (does not even need to be in xcm emulator level).

## Future directions

Check restructure parachains integration tests
[issue](https://github.com/paritytech/polkadot-sdk/issues/1389) and [PR
with more TODOs](https://github.com/paritytech/polkadot-sdk/pull/1693).

Needs https://github.com/sam0x17/macro_magic/pull/13

The associated PR allows the export of tokens from macro_magic at the
specified path. This fixes the path issue in derive-impl. Now, we can
import the default config using the standard rust syntax:

```rust
use frame_system::config_preludes::TestDefaultConfig;

[derive_impl(TestDefaultConfig as frame_system::DefaultConfig)]
impl frame_system::DefaultConfig for Test {
   //....
}
```

# Description

Upgrades `macro_magic` to 0.4.3, which introduces the ability to have
`export_tokens` use the same name as the underlying item for its
auto-generated macro name. Ultimately this will allow for better dev ux
in our derive_impl feature.

## Fixing stall

### Introduction
I experienced an apparent stall downloading state from
`https://rococo-try-runtime-node.parity-chains.parity.io:443` which was
having networking difficulties only responding to my JSONRPC requests
with 50-200KB/s of bandwidth.

This PR fixes the issue causing the stall, and generally improves
performance remote-ext when it downloads state by greatly reducing the
chances of a timeout occuring.

### Description
Introduces a new `REQUEST_DURATION_TARGET` constant and modifies
`get_storage_data_dynamic_batch_size` to

- Increase or decrease the batch size of the next request depending on
whether the elapsed time of the last request was gt or lt the target
- Reset the batch size to 1 if the request times out

This fixes an issue on slow connections that can otherwise cause
multiple timeouts and a stalled download when:

1. The batch size increases rapidly as remote-ext downloads keys with
small associated storage values
2. remote-ext tries to process a large series of subsequent keys all
with extremely large associated storage values (Rococo has a series of
keys 1-5MB large)
3. The huge storage values download for 5 minutes until the request
times out
4. The partially downloaded keys are thrown out and remote-ext tries
again with a smaller batch size, but the batch size is still far too
large and takes 5 minutes to be reduced again
5. The download will be essentially stalled for many hours while the
above step cycles


After this PR, the request size will

- Not grow as large to begin with, as it is regulated downwards as the
request duration exceeds the target
- Drop immediately to 1 if the request times out. A timeout indicates
the keys next in line to download have extremely large storage values
compared to previously downloaded keys, and we need to reset the batch
size to figure out what our new ideal batch size is. By not resetting
down to 1, we risk the next request timing out again.

## Reducing memory

As suggested by @bkchr, I adjusted `get_storage_data_dynamic_batch_size`
from being recursive to a loop which allows removing a bunch of clones
that were chewing through a lot of memory. I noticed actually it was
using up to 50GB swap previously when downloading Polkadot keys on a
slow connection, because it needed to recurse and clone a lot.

After this change it uses only ~1.5GB memory.

# Description
Update the DNS name of bootnodes to unify the deployment. 

Each bootnode have 3 port exposed: `30333, 30334, 443`. Before, we had
different DNS names for `30333, 30334` and `443` ports. It may confuse
people and give the impression that it is two different nodes. Fixing it
by using a single domain for all

Adds a warning to FRAME pallets when a function argument that starts
with `_` is used in the weight formula.
This is in most cases an error since the weight witness needs to be
checked.

Example:

```rust
#[pallet::call_index(0)]
#[pallet::weight(T::SystemWeightInfo::remark(_remark.len() as u32))]
pub fn remark(_origin: OriginFor<T>, _remark: Vec<u8>) -> DispatchResultWithPostInfo {
	Ok(().into())
}
```

Produces this warning:

```pre
warning: use of deprecated constant `pallet::warnings::UncheckedWeightWitness_0::_w`: 
                 It is deprecated to not check weight witness data.
                 Please instead ensure that all witness data for weight calculation is checked before usage.
         
                 For more info see:
                     <https://github.com/paritytech/polkadot-sdk/pull/1818>
   --> substrate/frame/system/src/lib.rs:424:40
    |
424 |         pub fn remark(_origin: OriginFor<T>, _remark: Vec<u8>) -> DispatchResultWithPostInfo {
    |                                              ^^^^^^^
    |
    = note: `#[warn(deprecated)]` on by default
```

Can be suppressed like this, since in this case it is legit:

```rust
#[pallet::call_index(0)]
#[pallet::weight(T::SystemWeightInfo::remark(remark.len() as u32))]
pub fn remark(_origin: OriginFor<T>, remark: Vec<u8>) -> DispatchResultWithPostInfo {
	let _ = remark; // We dont need to check the weight witness.
	Ok(().into())
}
```

Changes:
- Add warning on uncheded weight witness
- Respect `subkeys` limit in `System::kill_prefix`
- Fix HRMP pallet and other warnings
- Update`proc_macro_warning` dependency
- Delete random folder `substrate/src/src` 🙈

 
- Adding Prdoc

[xcm] Use `Weight::MAX` for `reserve_asset_deposited`, `receive_teleported_asset` benchmarks (#1726)

# Description

## Summary

Previously, the `pallet_xcm::do_reserve_transfer_assets` and
`pallet_xcm::do_teleport_assets` functions relied on weight estimation
for remote chain execution, which was based on guesswork derived from
the local chain. This approach led to complications for runtimes that
did not provide or support specific [XCM
configurations](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76/polkadot/xcm/xcm-executor/src/config.rs#L43-L47)
for `IsReserve` or `IsTeleporter`. Consequently, such runtimes had to
resort to implementing hard-coded weights for XCM instructions like
`reserve_asset_deposited` or `receive_teleported_asset` to support
extrinsics such as `pallet_xcm::reserve_transfer_assets` and
`pallet_xcm::teleport_assets`, which depended on remote weight
estimation.

The issue of remote weight estimation was addressed and resolved by
[Pull Request
#1645](https://github.com/paritytech/polkadot-sdk/pull/1645), which
removed the need for remote weight estimation.

## Solution

As a continuation of this improvement, the current PR proposes further
cleanup by removing unnecessary hard-coded values and rectifying
benchmark results with `Weight::MAX` that previously used
`T::BlockWeights::get().max_block` as an override for unsupported XCM
instructions like `ReserveAssetDeposited` and `ReceiveTeleportedAsset`.


## Questions

- [x] Can we remove now also `Hardcoded till the XCM pallet is fixed`
for `deposit_asset`? E.g. for AssetHubKusama
[here](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76/cumulus/parachains/runtimes/assets/asset-hub-kusama/src/weights/xcm/mod.rs#L129-L134)
- [x] Are comments like
[this](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76/polkadot/runtime/kusama/src/weights/xcm/mod.rs#L94)
`// Kusama doesn't support ReserveAssetDeposited, so this benchmark has
a default weight` still relevant? Shouldnt be removed/changed?


## TODO

- [x] `bench bot` regenerate xcm weights for all runtimes
- [x] remove hard-coded stuff from system parachain weight files
- [ ] when merged, open `polkadot-fellow/runtimes` PR

See #1345, <https://github.com/paritytech/substrate/pull/14207>.

This adds all the necessary mixnet components, and puts them together in
the "kitchen-sink" node/runtime. The components added are:

- A pallet (`frame/mixnet`). This is responsible for determining the
current mixnet session and phase, and the mixnodes to use in each
session. It provides a function that validators can call to register a
mixnode for the next session. The logic of this pallet is very similar
to that of the `im-online` pallet.
- A service (`client/mixnet`). This implements the core mixnet logic,
building on the `mixnet` crate. The service communicates with other
nodes using notifications sent over the "mixnet" protocol.
- An RPC interface. This currently only supports sending transactions
over the mixnet.

### Summary 

This PR introduces new dispatchables to the treasury pallet, allowing
spends of various asset types. The enhanced features of the treasury
pallet, in conjunction with the asset-rate pallet, are set up and
enabled for Westend and Rococo.

### Westend and Rococo runtimes.

Polkadot/Kusams/Rococo Treasury can accept proposals for `spends` of
various asset kinds by specifying the asset's location and ID.

#### Treasury Instance New Dispatchables:
- `spend(AssetKind, AssetBalance, Beneficiary, Option<ValidFrom>)` -
propose and approve a spend;
- `payout(SpendIndex)` - payout an approved spend or retry a failed
payout
- `check_payment(SpendIndex)` - check the status of a payout;
- `void_spend(SpendIndex)` - void previously approved spend;
> existing spend dispatchable renamed to spend_local

in this context, the `AssetKind` parameter contains the asset's location
and it's corresponding `asset_id`, for example:
`USDT` on `AssetHub`,
``` rust
location = MultiLocation(0, X1(Parachain(1000)))
asset_id = MultiLocation(0, X2(PalletInstance(50), GeneralIndex(1984)))
```

the `Beneficiary` parameter is a `MultiLocation` in the context of the
asset's location, for example
``` rust
// the Fellowship salary pallet's location / account
FellowshipSalaryPallet = MultiLocation(1, X2(Parachain(1001), PalletInstance(64)))
// or custom `AccountId`
Alice = MultiLocation(0, AccountId32(network: None, id: [1,...]))
```

the `AssetBalance` represents the amount of the `AssetKind` to be
transferred to the `Beneficiary`. For permission checks, the asset
amount is converted to the native amount and compared against the
maximum spendable amount determined by the commanding spend origin.

the `spend` dispatchable allows for batching spends with different
`ValidFrom` arguments, enabling milestone-based spending. If the
expectations tied to an approved spend are not met, it is possible to
void the spend later using the `void_spend` dispatchable.

Asset Rate Pallet provides the conversion rate from the `AssetKind` to
the native balance.

#### Asset Rate Instance Dispatchables:
- `create(AssetKind, Rate)` - initialize a conversion rate to the native
balance for the given asset
- `update(AssetKind, Rate)` - update the conversion rate to the native
balance for the given asset
- `remove(AssetKind)` - remove an existing conversion rate to the native
balance for the given asset

the pallet's dispatchables can be executed by the Root or Treasurer
origins.

### Treasury Pallet

Treasury Pallet can accept proposals for `spends` of various asset kinds
and pay them out through the implementation of the `Pay` trait.

New Dispatchables:
- `spend(Config::AssetKind, AssetBalance, Config::Beneficiary,
Option<ValidFrom>)` - propose and approve a spend;
- `payout(SpendIndex)` - payout an approved spend or retry a failed
payout;
- `check_payment(SpendIndex)` - check the status of a payout;
- `void_spend(SpendIndex)` - void previously approved spend;
> existing spend dispatchable renamed to spend_local

The parameters' types of the `spend` dispatchable exposed via the
pallet's `Config` and allows to propose and accept a spend of a certain
amount.

An approved spend can be claimed via the `payout` within the
`Config::SpendPeriod`. Clients provide an implementation of the `Pay`
trait which can pay an asset of the `AssetKind` to the `Beneficiary` in
`AssetBalance` units.

The implementation of the Pay trait might not have an immediate final
payment status, for example if implemented over `XCM` and the actual
transfer happens on a remote chain.

The `check_status` dispatchable can be executed to update the spend's
payment state and retry the `payout` if the payment has failed.
