      XCMv4 (#1230) · 8428f678
      Francisco Aguirre authored 
      

# 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

This PR should fix this.

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

      Broker pallet: fix interlacing (#2811) · ae14e6da
      Sergej Sakac authored 
      With the current code, when a user interlaces their region, the end
result will be three regions in the state:
- the non-interlaced region
- first part of the interlaced region
- second part of the interlaced region

The existing implementation retains the non-interlaced region in the
state, leading to a problematic scenario:

1. User 1 acquires a region from the market.
2. User 1 then interlaces this region.
3. Subsequently, User 1 transfers one part of the interlaced regions to
User 2.
Despite this transfer, User 1 retains the ability to assign the entire
original non-interlaced region, which is inconsistent with the fact that
they no longer own one of the interlaced parts.

This PR resolves the issue by removing the original region, ensuring
that only the two new interlaced regions remain in the state.
