Note:

It's also possible to remove the Identity Migrator pallet from both the
Relay Chain and the parachain at this time. I will leave them in for now
to preserve the test cases until we run them on Kusama/Polkadot. We will
also want a follow up to remove all Identity-related state from the
Relay Chain.

This PR backports version bumps from release branch
`release-polkadot-v1.6.0` back to `master` and also moved `prdoc` files
related to the release to the appropriate folder

This will allow us to change to the target supporting atomics and makes
the linker file no longer necessary.

After People Rococo deployment, we noticed that `safeXcmVersion` wasn't
initialised.

I think it is due to `Storage` missing in the pallet's declaration. This
PR should fix it.

# Note for reviewer

Most changes are just syntax changes necessary for the new version.
Most important files should be the ones under the `xcm` folder.

# Description 

Added XCMv4.

## Removed `Multi` prefix
The following types have been renamed:
- MultiLocation -> Location
- MultiAsset -> Asset
- MultiAssets -> Assets
- InteriorMultiLocation -> InteriorLocation
- MultiAssetFilter -> AssetFilter
- VersionedMultiAsset -> VersionedAsset
- WildMultiAsset -> WildAsset
- VersionedMultiLocation -> VersionedLocation

In order to fix a name conflict, the `Assets` in `xcm-executor` were
renamed to `HoldingAssets`, as they represent assets in holding.

## Removed `Abstract` asset id

It was not being used anywhere and this simplifies the code.

Now assets are just constructed as follows:

```rust
let asset: Asset = (AssetId(Location::new(1, Here)), 100u128).into();
```

No need for specifying `Concrete` anymore.

## Outcome is now a named fields struct

Instead of

```rust
pub enum Outcome {
  Complete(Weight),
  Incomplete(Weight, Error),
  Error(Error),
}
```

we now have

```rust
pub enum Outcome {
  Complete { used: Weight },
  Incomplete { used: Weight, error: Error },
  Error { error: Error },
}
```

## Added Reanchorable trait

Now both locations and assets implement this trait, making it easier to
reanchor both.

## New syntax for building locations and junctions

Now junctions are built using the following methods:

```rust
let location = Location {
    parents: 1,
    interior: [Parachain(1000), PalletInstance(50), GeneralIndex(1984)].into()
};
```

or

```rust
let location = Location::new(1, [Parachain(1000), PalletInstance(50), GeneralIndex(1984)]);
```

And they are matched like so:

```rust
match location.unpack() {
  (1, [Parachain(id)]) => ...
  (0, Here) => ...,
  (1, [_]) => ...,
}
```

This syntax is mandatory in v4, and has been also implemented for v2 and
v3 for easier migration.

This was needed to make all sizes smaller.

# TODO
- [x] Scaffold v4
- [x] Port github.com/paritytech/polkadot/pull/7236
- [x] Remove `Multi` prefix
- [x] Remove `Abstract` asset id

## Why we need it
To provide another level of understanding to why polkadot's subsystems
may perform slower than expected. Cache misses occur when processing
large amounts of data, such as during availability recovery.

## Why Cachegrind
Cachegrind has many drawbacks: it is slow, it uses its own cache
simulation, which is very basic. But unlike `perf`, which is a great
tool, Cachegrind can run in a virtual machine. This means we can easily
run it in remote installations and even use it in CI/CD to catch
possible regressions.

Why Cachegrind and not Callgrind, another part of Valgrind? It is simply
empirically proven that profiling runs faster with Cachegrind.

## First results
First results have been obtained while testing of the approach. Here is
an example.

```
$ target/testnet/subsystem-bench --n-cores 10 --cache-misses data-availability-read
$ cat cachegrind_report.txt
I refs:        64,622,081,485
I1  misses:         3,018,168
LLi misses:           437,654
I1  miss rate:           0.00%
LLi miss rate:           0.00%

D refs:        12,161,833,115  (9,868,356,364 rd   + 2,293,476,751 wr)
D1  misses:       167,940,701  (   71,060,073 rd   +    96,880,628 wr)
LLd misses:        33,550,018  (   16,685,853 rd   +    16,864,165 wr)
D1  miss rate:            1.4% (          0.7%     +           4.2%  )
LLd miss rate:            0.3% (          0.2%     +           0.7%  )

LL refs:          170,958,869  (   74,078,241 rd   +    96,880,628 wr)
LL misses:         33,987,672  (   17,123,507 rd   +    16,864,165 wr)
LL miss rate:             0.0% (          0.0%     +           0.7%  )
```

The CLI output shows that 1.4% of the L1 data cache missed, which is not
so bad, given that the last-level cache had that data most of the time
missing only 0.3%. Instruction data of the L1 has 0.00% misses of the
time. Looking at an output file with `cg_annotate` shows that most of
the misses occur during reed-solomon, which is expected.

Implements an XCM executor `WeightTrader`, facilitating fee payments in
any asset that can be exchanged for a native asset.

A few constraints need to be observed:
- `buy_weight` and `refund` operations must be atomic, as another weight
trader implementation might be attempted in case of failure.
- swap credit must be utilized since there isn’t an account to which an
asset of some class can be deposited with a guarantee to meet the
existential deposit requirement. Also, operating with credits enhances
the efficiency of the weight trader -

Integration tests in ink!:
https://github.com/paritytech/ink/tree/master/integration-tests/sr25519-verification

Changes:
- add missing member to the workspace
- add CI script after the last attempt to merge it upstream failed
https://github.com/paritytech/pipeline-scripts/pull/105

Two crates are excluded from the check since they are templates
`substrate/frame/contracts/fixtures/build` and
 `substrate/frame/contracts/fixtures/contracts/common`.

Hopefully this is the last time that some crates need to be added
manually.

This PR implements the `archive_unstable_storage` method that offers
support for:
- fetching values
- fetching hashes
- iterating over keys and values
- iterating over keys and hashes
- fetching merkle values from the trie-db

A common component dedicated to RPC-V2 storage queries is created to
bridge the gap between `chainHead/storage` and `archive/storage`.
Query pagination is supported by `paginationStartKey`, similar to the
old APIs.
Similarly to the `chainHead/storage`, the `archive/storage` method
accepts a maximum number of queried items.

The design builds upon:
https://github.com/paritytech/json-rpc-interface-spec/pull/94.
Closes https://github.com/paritytech/polkadot-sdk/issues/1512.

Partial https://github.com/paritytech/polkadot-sdk/issues/225

- [x] Adds conformance tests for Unbalanced
- [x] Adds conformance tests for Balanced
- Several minor fixes to fungible default implementations and the
Balances pallet
- [x] `Unbalanced::decrease_balance` can reap account when
`Preservation` is `Preserve`
- [x] `Balanced::pair` can return pairs of imbalances which do not
cancel each other out
   - [x] Balances pallet `active_issuance` 'underflow'
- [x] Refactors the conformance test file structure to match the
fungible file structure: tests for traits in regular.rs go into a test
file named regular.rs, tests for traits in freezes.rs go into a test
file named freezes.rs, etc.
 - [x] Improve doc comments
 - [x] Simplify macros

## Fixes

### `Unbalanced::decrease_balance` can reap account when called with
`Preservation::Preserve`
There is a potential issue in the default implementation of
`Unbalanced::decrease_balance`. The implementation can delete an account
even when it is called with `preservation: Preservation::Preserve`. This
seems to contradict the documentation of `Preservation::Preserve`:

```rust
	/// The account may not be killed and our provider reference must remain (in the context of
	/// tokens, this means that the account may not be dusted).
	Preserve,
```

I updated `Unbalanced::decrease_balance` to return
`Err(TokenError::BelowMinimum)` when a withdrawal would cause the
account to be reaped and `preservation: Preservation::Preserve`.

- [ ] TODO Confirm with @gavofyork that this is correct behavior

Test for this behavior:


https://github.com/paritytech/polkadot-sdk/blob/e5c876dd/substrate/frame/support/src/traits/tokens/fungible/conformance_tests/regular.rs#L912-L937

### `Balanced::pair` returning non-canceling pairs

`Balanced::pair` is supposed to create a pair of imbalances that cancel
each other out. However this is not the case when the method is called
with an amount greater than the total supply.

In the existing default implementation, `Balanced::pair` creates a pair
by first rescinding the balance, creating `Debt`, and then issuing the
balance, creating `Credit`.

When creating `Debt`, if the amount to create exceeds the
`total_supply`, `total_supply` units of `Debt` are created *instead* of
`amount` units of `Debt`. This can lead to non-canceling amount of
`Credit` and `Debt` being created.

To address this, I create the credit and debt directly in the method
instead of calling `issue` and `rescind`.

Test for this behavior:


https://github.com/paritytech/polkadot-sdk/blob/e5c876dd/substrate/frame/support/src/traits/tokens/fungible/conformance_tests/regular.rs#L1323-L1346

### `Balances` pallet `active_issuance` 'underflow'

This PR resolves an issue in the `Balances` pallet that can lead to odd
behavior of `active_issuance`.

Currently, the Balances pallet doesn't check if `InactiveIssuance`
remains less than or equal to `TotalIssuance` when supply is
deactivated. This allows `InactiveIssuance` to be greater than
`TotalIssuance`, which can result in unexpected behavior from the
perspective of the fungible API.

`active_issuance` is derived from
`TotalIssuance.saturating_sub(InactiveIssuance)`.

If an `amount` is deactivated that causes `InactiveIssuance` to become
greater TotalIssuance, `active_issuance` will return 0. However once in
that state, reactivating an amount will not increase `active_issuance`
by the reactivated `amount` as expected.

Consider this test where the last assertion would fail due to this
issue:


https://github.com/paritytech/polkadot-sdk/blob/e5c876dd

/substrate/frame/support/src/traits/tokens/fungible/conformance_tests/regular.rs#L1036-L1071

To address this, I've modified the `deactivate` function to ensure
`InactiveIssuance` never surpasses `TotalIssuance`.

Regenerating the DB snapshot after fixing:
https://github.com/paritytech/polkadot-sdk/pull/2919

Now we can add some BEEFY checks to `0002-validators-warp-sync`

Hi folks!

Thank for the well organized codebase and an outstanding engineering!

I am trying to compile a substrate node template from source
(https://github.com/paritytech/polkadot-sdk) and encountered a
dependency conflict
![Screenshot 2024-01-11 at 12 22
16](https://github.com/paritytech/polkadot-sdk/assets/16288656/b630773f-9d58-4abc-a15c-45f0e6b96b48)
and a deprecation warning from advisory db for `ansi_term` (I see you
replace it with some alternatives in other crates).

While for `ansi_term` there is an adopted fork
(https://github.com/rustadopt/ansiterm-rs) and it was my first commit in
the PR, I've decided to use https://github.com/console-rs/console as you
already use it to reduce dependencies (as I believe other substrate
crates will remove ansi_term eventually)

This version includes
- Performance improvements.
- Minor fixes.

Extract `WarpSync` (and `StateSync` as part of warp sync) from
`ChainSync` as independent syncing strategy called by `SyncingEngine`.
Introduce `SyncingStrategy` enum as a proxy between `SyncingEngine` and
specific syncing strategies.

## Limitations
Gap sync is kept in `ChainSync` for now because it shares the same set
of peers as block syncing implementation in `ChainSync`. Extraction of a
common context responsible for peer management in syncing strategies
able to run in parallel is planned for a follow-up PR.

## Further improvements
A possibility of conversion of `SyncingStartegy` into a trait should be
evaluated. The main stopper for this is that different strategies need
to communicate different actions to `SyncingEngine` and respond to
different events / provide different APIs (e.g., requesting
justifications is only possible via `ChainSync` and not through
`WarpSync`; `SendWarpProofRequest` action is only relevant to
`WarpSync`, etc.)

Brridges zombienet tests are non-standard - zombienet currently missing
multiple relay chains support (see e.g.
https://github.com/paritytech/zombienet/pull/796), so we need to go live
with two relay networks, their parachains + custom test runner (which
e.g. doesn't shutdown net when its tests are finished and instead waits
for both networks tests to complete). So we are stuck with native
zombienet provider => this PR is an attempt to gather everything in a
single docker container and run tests there ~Draft, because it is far
from finishing - what I want now is to see how it works on CI~

Fixes `pallet_mmr::Config` for the kitchensink runtime

A recent referendum failed because the parachain's sovereign account had
enough funds for the deposit (the runtime at the time required a
deposit) but not enough left over for the existential deposit, which
must remain free.

The current logic does not require a deposit for channels with system
chains, and the current tests check that none is taken. This new test
simply ensures that even without any balance in a parachain's sovereign
account, opening a channel with a system chain will be successful.

Bumps [indexmap](https://github.com/bluss/indexmap) from 1.9.3 to 2.0.0.

<p><em>Sourced from <a
href="https://github.com/bluss/indexmap/blob/master/RELEASES.md">indexmap's
changelog</a>.</em></p>
<blockquote>
<ul>
<li>
<p>2.0.0</p>
<ul>
<li>
<p><strong>MSRV</strong>: Rust 1.64.0 or later is now required.</p>
</li>
<li>
<p>The <code>&quot;std&quot;</code> feature is no longer auto-detected.
It is included in the
default feature set, or else can be enabled like any other Cargo
feature.</p>
</li>
<li>
<p>The <code>&quot;serde-1&quot;</code> feature has been removed,
leaving just the optional
<code>&quot;serde&quot;</code> dependency to be enabled like a feature
itself.</p>
</li>
<li>
<p><code>IndexMap::get_index_mut</code> now returns
<code>Option&lt;(&amp;K, &amp;mut V)&gt;</code>, changing
the key part from <code>&amp;mut K</code> to <code>&amp;K</code>. There
is also a new alternative
<code>MutableKeys::get_index_mut2</code> to access the former
behavior.</p>
</li>
<li>
<p>The new <code>map::Slice&lt;K, V&gt;</code> and
<code>set::Slice&lt;T&gt;</code> offer a linear view of maps
and sets, behaving a lot like normal <code>[(K, V)]</code> and
<code>[T]</code> slices. Notably,
comparison traits like <code>Eq</code> only consider items in order,
rather than hash
lookups, and slices even implement <code>Hash</code>.</p>
</li>
<li>
<p><code>IndexMap</code> and <code>IndexSet</code> now have
<code>sort_by_cached_key</code> and
<code>par_sort_by_cached_key</code> methods which perform stable sorts
in place
using a key extraction function.</p>
</li>
<li>
<p><code>IndexMap</code> and <code>IndexSet</code> now have
<code>reserve_exact</code>, <code>try_reserve</code>, and
<code>try_reserve_exact</code> methods that correspond to the same
methods on <code>Vec</code>.
However, exactness only applies to the direct capacity for items, while
the
raw hash table still follows its own rules for capacity and load
factor.</p>
</li>
<li>
<p>The <code>Equivalent</code> trait is now re-exported from the
<code>equivalent</code> crate,
intended as a common base to allow types to work with multiple map
types.</p>
</li>
<li>
<p>The <code>hashbrown</code> dependency has been updated to version
0.14.</p>
</li>
<li>
<p>The <code>serde_seq</code> module has been moved from the crate root
to below the
<code>map</code> module.</p>
</li>
</ul>
</li>
</ul>

closes #2567 

Followup for https://github.com/paritytech/polkadot-sdk/pull/2331

This PR contains multiple internal cleanups:

1. This gets rid of the functionality in `generate_genesis_block` which
was only used in one benchmark
2. Fixed `transaction_pool` and `transaction_throughput` benchmarks
failing since they require a tokio runtime now.
3. Removed `parachain_id` CLI option from the test parachain
4. Removed `expect` call from `RuntimeResolver`

Trivial refactoring, fixes
https://github.com/paritytech/polkadot-sdk/issues/2885

<del>PR custom review is deprecated. Now `review-bot` performs these
functions.</del>
PR removes unused ci jobs and adjusts zombienet jobs for merge queues

cc @Bullrich

The XCM instruction limit of 100 was being hit by the 1 large message
before. The weight ref time also needed to be bumped for these
extrinsics.

Part of https://github.com/paritytech/polkadot-sdk/issues/2787

This is an initial PR that adds some basic BEEFY checks to the warp sync
zombienet tests. To be more specific, it does the following:
- Changes the snapshot used by the warp sync zombienet tests to one
built from an updated version of the kitchensink runtime, that supports
BEEFY
- Adds some basic BEEFY checks to the warp sync zombienet tests
- Deduplicates some params of the warp sync zombienet tests, making them
easier to extend

`frame-support` crate compilation fails (reported by @koute):

```
$ cargo check --no-default-features --target=wasm32-unknown-unknown

```

This PR should fix this.

For all runtimes `sp-runtime/serde` feature was likely enabled by this
(and few other pallets):

https://github.com/paritytech/polkadot-sdk/blob/f2a750ee/substrate/frame/system/Cargo.toml#L27

- updates snowbridge crates to `0.9.0`
- updates Cargo.toml files in preparation for publishing to crates.io
- adds Kusama and Polkadot Snowbridge runtime config crates
- moves runtime tests from the Snowbridge subtree into the bridge hub
tests dir

Considering the complexity of
https://github.com/paritytech/polkadot-sdk/pull/2871 and the discussion
therein, as well as the further complexity introduced by the hardening
in https://github.com/paritytech/polkadot-sdk/pull/2742, as well as the
eventual replacement of wasmtime by PolkaVM, it seems best to remove
this persistence as it is creating more problems than it solves.
