Disallow reserve transfers that use teleportable fees if `(origin, fees)` matches `XcmTeleportFilter`. Add regression tests for filtering based on `XcmTeleportFilter` for both `(limited_)reserve_transfer_assets()` and `(limited_)teleport_assets` extrinsics.

## Motivation `pallet-xcm` is the main user-facing interface for XCM functionality, including assets manipulation functions like `teleportAssets()` and `reserve_transfer_assets()` calls. While `teleportAsset()` works both ways, `reserve_transfer_assets()` works only for sending reserve-based assets to a remote destination and beneficiary when the reserve is the _local chain_. ## Solution This PR enhances `pallet_xcm::(limited_)reserve_withdraw_assets` to support transfers when reserves are other chains. This will allow complete, **bi-directional** reserve-based asset transfers user stories using `pallet-xcm`. Enables following scenarios: - transferring assets with local reserve (was previously supported iff asset used as fee also had local reserve - now it works in all cases), - transferring assets with reserve on destination, - transferring assets with reserve on remote/third-party chain (iff assets and fees have same remote reserve), - transferring assets with reserve different than the reserve of the asset to be used as fees - meaning can be used to transfer random asset with local/dest reserve while using DOT for fees on all involved chains, even if DOT local/dest reserve doesn't match asset reserve, - transferring assets with any type of local/dest reserve while using fees which can be teleported between involved chains. All of the above is done by pallet inner logic without the user having to specify which scenario/reserves/teleports/etc. The correct scenario and corresponding XCM programs are identified, and respectively, built automatically based on runtime configuration of trusted teleporters and trusted reserves. #### Current limitations: - while `fees` and "non-fee" `assets` CAN have different reserves (or fees CAN be teleported), the remaining "non-fee" `assets` CANNOT, among themselves, have different reserve locations (this is also implicitly enforced by `MAX_ASSETS_FOR_TRANSFER=2`, but this can be safely increased in the future). - `fees` and "non-fee" `assets` CANNOT have **different remote** reserves (this could also be supported in the future, but adds even more complexity while possibly not being worth it - we'll see what the future holds).

We are introducing a new set of `XcmController` traits (final name yet to be determined). These traits are implemented by `pallet-xcm` and allows other pallets, such as `pallet_contracts`, to rely on these traits instead of tight coupling them to `pallet-xcm`. Using only the existing Xcm traits would mean duplicating the logic from `pallet-xcm` in these other pallets, which we aim to avoid. Our objective is to ensure that when these APIs are called from `pallet-contracts`, they produce the exact same outcomes as if called directly from `pallet-xcm`. The other benefits is that we can also expose return values to `pallet-contracts` instead of just calling `pallet-xcm` dispatchable and getting a `DispatchResult` back. See traits integration in this PR https://github.com/paritytech/polkadot-sdk/pull/1248, where the traits are used as follow to define and implement `pallet-contracts` Config. ```rs // Contracts config: pub trait Config: frame_system::Config { // ... /// A type that exposes XCM APIs, allowing contracts to interact with other parachains, and /// execute XCM programs. type Xcm: xcm_executor::traits::Controller< OriginFor<Self>, <Self as frame_system::Config>::RuntimeCall, BlockNumberFor<Self>, >; } // implementation impl pallet_contracts::Config for Runtime { // ... type Xcm = pallet_xcm::Pallet<Self>; } ``` --------- Co-authored-by:Alexander Theißen <[email protected]> Co-authored-by: command-bot <>

closes https://github.com/paritytech/polkadot-sdk/issues/1882 ## Breaking Changes This PR introduces a new item to `pallet_balances::Config`: ```diff trait Config { ++ type RuntimeFreezeReasons; } ``` This value is only used to check it against `type MaxFreeze`. A similar check has been added for `MaxHolds` against `RuntimeHoldReasons`, which is already given to `pallet_balances`. In all contexts, you should pass the real `RuntimeFreezeReasons` generated by `construct_runtime` to `type RuntimeFreezeReasons`. Passing `()` would also work, but it would imply that the runtime uses no freezes at all. --------- Signed-off-by:

The `xcm` crate was renamed to `staging-xcm` to be able to publish it to crates.io as someone as squatted `xcm`. The problem with this rename is that the `TypeInfo` includes the crate name which ultimately lands in the metadata. The metadata is consumed by downstream users like `polkadot-js` or people building on top of `polkadot-js`. These people are using the entire `path` to find the type in the type registry. Thus, their code would break as the type path would now be [`staging_xcm`, `VersionedXcm`] instead of [`xcm`, `VersionedXcm`]. This pull request fixes this by renaming the path segment `staging_xcm` to `xcm`. This requires: https://github.com/paritytech/scale-info/pull/197 --------- Co-authored-by:

Combination of paritytech/polkadot#7005, its addon PR paritytech/polkadot#7585 and its companion paritytech/cumulus#2433. This PR introduces a new XcmFeesToAccount struct which implements the `FeeManager` trait, and assigns this struct as the `FeeManager` in the XCM config for all runtimes. The struct simply deposits all fees handled by the XCM executor to a specified account. In all runtimes, the specified account is configured as the treasury account. XCM __delivery__ fees are now being introduced (unless the root origin is sending a message to a system parachain on behalf of the originating chain). # Note for reviewers Most file changes are tests that had to be modified to account for the new fees. Main changes are in: - cumulus/pallets/xcmp-queue/src/lib.rs <- To make it track the delivery fees exponential factor - polkadot/xcm/xcm-builder/src/fee_handling.rs <- Added. Has the FeeManager implementation - All runtime xcm_config files <- To add the FeeManager to the XCM configuration # Important note After this change, instructions that create and send a new XCM (Query*, Report*, ExportMessage, InitiateReserveWithdraw, InitiateTeleport, DepositReserveAsset, TransferReserveAsset, LockAsset and RequestUnlock) will require the corresponding origin account in the origin register to pay for transport delivery fees, and the onward message will fail to be sent if the origin account does not have the required amount. This delivery fee is on top of what we already collect as tx fees in pallet-xcm and XCM BuyExecution fees! Wallet UIs that want to expose the new delivery fee can do so using the formula: ``` delivery_fee_factor * (base_fee + encoded_msg_len * per_byte_fee) ``` where the delivery fee factor can be obtained from the corresponding pallet based on which transport you are using (UMP, HRMP or bridges), the base fee is a constant, the encoded message length from the message itself and the per byte fee is the same as the configured per byte fee for txs (i.e. `TransactionByteFee`). --------- Co-authored-by:

Two old functions should be deprecated and have their code altered in line with capabilities of XCMv2 and above. This means we can use the proper `Unlimited` form of weight limit rather than guessing weight from the local chain.

`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.
