Fix issue where setting the `remote_fees` field of `InitiateTransfer` to
`None` could lead to unintended bypassing of fees in certain conditions.

Changes made to fix this:
- `remote_fees: None` now results in the `UnpaidExecution` instruction
being appended *after* the origin altering instruction, be it
`AliasOrigin` or `ClearOrigin`. This means `preserve_origin: true` must
be set if you want to have any chance of not paying for fees.
- The `AliasOrigin` instruction is not appended if the executor is
called with the root location (`Here`) since it would alias to itself.
Although this self-aliasing could be done, it needs the ecosystem to add
a new aliasing instruction, so we just skip it.
- Tweaked the `AllowExplicitUnpaidExecutionFrom` barrier to allow
receiving assets (via teleport or reserve asset transfer) and altering
the origin before actually using `UnpaidExecution`. This is to allow
unpaid teleports to work with `InitiateTransfer`.
- For...

Add a new extrinsic `dispatch_as_fallible`.

It's almost the same as [`Pallet::dispatch_as`] but forwards any error
of the inner call.

Closes #219.

And add more unit tests to cover `dispatch_as` and
`dispatch_as_fallible`.

This PR fixes the invalid prdoc, and add a ci job to check the prdoc are

Recreation of https://github.com/paritytech/polkadot-sdk/pull/7357 on
top of master. The old PR messes up the git history too much so I am
recreating it from scratch.

This PR is work in progress. It's purpose is to commit initial structure
of `pallet-staking-ah-client` and `pallet-staking-rc-client` to master.
The changes will be polished by a follow up PRs which will be
backported.

Related issues: https://github.com/paritytech/polkadot-sdk/issues/6167
and https://github.com/paritytech/polkadot-sdk/issues/6166

This PR introduces the initial structure for `pallet-ah-client` and
`pallet-rc-client`. These pallets will reside on the relay chain and
AssetHub, respectively, and will manage the interaction between
`pallet-session` on the relay chain and `pallet-staking` on AssetHub.

Both pallets are experimental and not intended for production use.

TODOs:
- [ ] Probably handle
https://github.com/paritytech/polkadot-sdk/issues/6344 here.

closes https://github.com/paritytech/polkadot-sdk/issues/3610.

helps https://github.com/paritytech/polkadot-sdk/issues/6344, but need
to migrate storage `Offences::Reports` before we can remove exposure
dependency in RC pallets.

replaces https://github.com/paritytech/polkadot-sdk/issues/6788.

## Context  
Slashing in staking is unbounded currently, which is a major blocker
until staking can move to a parachain (AH).

### Current Slashing Process (Unbounded)  

1. **Offence Reported**  
- Offences include multiple validators, each with potentially large
exposure pages.
- Slashes are **computed immediately** and scheduled for application
after **28 eras**.

2. **Slash Applied**  
- All unapplied slashes are executed in **one block** at the start of
the **28th era**. This is an **unbounded operation**.


### Proposed Slashing Process (Bounded)  

1. **Offence Queueing**  
   - Offences are **queued** after basic sanity checks.  

2. **Paged Offence Processing (Computing Slash)**  
   - Slashes are **computed one validator exposure page at a time**.  
   - **Unapplied slashes** are stored in a **double map**:  
     - **Key 1 (k1):** `EraIndex`  
- **Key 2 (k2):** `(Validator, SlashFraction, PageIndex)` — a unique
identifier for each slash page

3. **Paged Slash Application**  
- Slashes are **applied one page at a time** across multiple blocks.
- Slash application starts at the **27th era** (one era earlier than
before) to ensure all slashes are applied **before stakers can unbond**
(which starts from era 28 onwards).

---

## Worst-Case Block Calculation for Slash Application  

### Polkadot:  
- **1 era = 24 hours**, **1 block = 6s** → **14,400 blocks/era**  
- On parachains (**12s blocks**) → **7,200 blocks/era**  

### Kusama:  
- **1 era = 6 hours**, **1 block = 6s** → **3,600 blocks/era**  
- On parachains (**12s blocks**) → **1,800 blocks/era**  

### Worst-Case Assumptions:  
- **Total stakers:** 40,000 nominators, 1000 validators. (Polkadot
currently has ~23k nominators and 500 validators)
- **Max slashed:** 50% so 20k nominators, 250 validators.  
- **Page size:** Validators with multiple page: (512 + 1)/2 = 256 ,
Validators with single page: 1

### Calculation:  
There might be a more accurate way to calculate this worst-case number,
and this estimate could be significantly higher than necessary, but it
shouldn’t exceed this value.

Blocks needed: 250 + 20k/256 = ~330 blocks.

##  *Potential Improvement:*  
- Consider adding an **Offchain Worker (OCW)** task to further optimize
slash application in future updates.
- Dynamically batch unapplied slashes based on number of nominators in
the page, or process until reserved weight limit is exhausted.

## Summary of Changes  

### Storage  
- **New:**  
  - `OffenceQueue` *(StorageDoubleMap)*  
    - **K1:** Era  
    - **K2:** Offending validator account  
    - **V:** `OffenceRecord`  
  - `OffenceQueueEras` *(StorageValue)*  
    - **V:** `BoundedVec<EraIndex, BoundingDuration>`  
  - `ProcessingOffence` *(StorageValue)*  
    - **V:** `(Era, offending validator account, OffenceRecord)`  

- **Changed:**  
  - `UnappliedSlashes`:  
    - **Old:** `StorageMap<K -> Era, V -> Vec<UnappliedSlash>>`  
- **New:** `StorageDoubleMap<K1 -> Era, K2 -> (validator_acc, perbill,
page_index), V -> UnappliedSlash>`

### Events  
- **New:**  
  - `SlashComputed { offence_era, slash_era, offender, page }`  
  - `SlashCancelled { slash_era, slash_key, payout }`  

### Error  
- **Changed:**  
  - `InvalidSlashIndex` → Renamed to `InvalidSlashRecord`  
- **Removed:**  
  - `NotSortedAndUnique`  
- **Added:**  
  - `EraNotStarted`  

### Call  
- **Changed:**  
  - `cancel_deferred_slash(era, slash_indices: Vec<u32>)`  
    → Now takes `Vec<(validator_acc, slash_fraction, page_index)>`  
- **New:**  
- `apply_slash(slash_era, slash_key: (validator_acc, slash_fraction,
page_index))`

### Runtime Config  
- `FullIdentification` is now set to a unit type (`()`) / null identity,
replacing the previous exposure type for all runtimes using
`pallet_session::historical`.

## TODO
- [x] Fixed broken `CancelDeferredSlashes`.
- [x] Ensure on_offence called only with validator account for
identification everywhere.
- [ ] Ensure we never need to read full exposure.
- [x] Tests for multi block processing and application of slash.
- [x] Migrate UnappliedSlashes 
- [x] Bench (crude, needs proper bench as followup)
  - [x] on_offence()
  - [x] process_offence()
  - [x] apply_slash()
 
 
## Followups (tracker
[link](https://github.com/paritytech/polkadot-sdk/issues/7596))
- [ ] OCW task to process offence + apply slashes.
- [ ] Minimum time for governance to cancel deferred slash.
- [ ] Allow root or staking admin to add a custom slash.
- [ ] Test HistoricalSession proof works fine with eras before removing
exposure as full identity.
- [ ] Properly bench offence processing and slashing.
- [ ] Handle Offences::Reports migration when removing validator
exposure as identity.

# Utility Call Fallback

This introduces a new extrinsic: **`if_else`**

Which first attempts to dispatch the `main` call(s). If the `main`
call(s) fail, the `fallback` call(s) is dispatched instead. Both calls
are executed with the same origin.

In the event of a fallback failure the whole call fails with the weights
returned.

## Use Case
Some use cases might involve submitting a `batch` type call in either
main, fallback or both.

## Multi Block Election Pallet

This PR adds the first iteration of the multi-block staking pallet. 

From this point onwards, the staking and its election provider pallets
are being customized to work in AssetHub. While usage in solo-chains is
still possible, it is not longer the main focus of this pallet. For a
safer usage, please fork and user an older version of this pallet.

#### Description 
Currently the transaction which is reported as invalid by a block
builder (or `removed_invalid` by other components) is silently skipped.

This PR improves this behavior. The transaction pool `report_invalid`
function now accepts optional error associated with every reported
transaction, and also the optional block hash which provides hints how
reported transaction shall be handled. The following API change is
proposed:

https://github.com/paritytech/polkadot-sdk/blob/8be5ef3e/substrate/client/transaction-pool/api/src/lib.rs#L297-L318
Depending on error, the transaction pool can decide if transaction shall
be removed from the view only or entirely from the pool. Invalid event
will be dispatched if required.


#### Notes for reviewers

- Actual logic of removing invalid txs is implented in
[`ViewStore::report_invalid`](https://github.com/paritytech/polkadot-sdk/blob/0fad26c4...

Partly addresses https://github.com/paritytech/polkadot-sdk/issues/6157

The benchmarks measuring the impact of contract sizes on calling or
instantiating a contract were bogus because they needed to be written in
assembly in order to tightly control the basic block size.

This fixes the benchmarks for:
- call_with_code_per_byte
- upload_code
- instantiate_with_code

And adds a new benchmark that accounts for the fact that the interpreter
will always compile whole basic blocks:
- basic_block_compilation

After this PR only the weight we assign to instructions need to be
addressed.

# Description

Currently, the `#[benchmarks]` macro always add `<T:Config>` to the
expanded code even if a where clause is used. Using a where clause which
also includes a trait bound for the generic `T` is triggering [this
clippy
warning](https://rust-lang.github.io/rust-clippy/master/index.html#multiple_bound_locations)
from Rust 1.78 onwards. We've found that
[here](https://github.com/freeverseio/laos/blob/main/pallets/precompiles-benchmark/src/precompiles/vesting/benchmarking.rs#L126-L132)
in LAOS, as we need to include `T: pallet_vesting::Config` in the where
clause, here's the outcome:

```rust
error: bound is defined in more than one place
   --> pallets/precompiles-benchmark/src/precompiles/vesting/benchmarking.rs:130:1

When trying to reproduce bugs we sometimes need to deploy code that
wouldn't pass validation. This PR adds a new environment variable
`REVIVE_SKIP_VALIDATION` that when set will skip all validation except
the contract blob size limit.

Please note that this only applies to when the pallet is compiled for
`std` and hence will never be part of on-chain.

Changes:
- Expose a `force_set_head` function from the `MessageQueue` pallet via
a new trait: `ForceSetHead`. This can be used to force the MQ pallet to
process this queue next.
- The change only exposes an internal function through a trait, no audit
is required.

## Context

For the Asset Hub Migration (AHM) we need a mechanism to prioritize the
inbound upward messages and the inbound downward messages on the AH. To
achieve this, a minimal (and no breaking) change is done to the MQ
pallet in the form of adding the `force_set_head` function.

An example use of how to achieve prioritization is then demonstrated in
`integration_test.rs::AhmPrioritizer`. Normally, all queues are
scheduled round-robin like this:

`| Relay | Para(1) | Para(2) | ... | Relay | ... `

The prioritizer listens to changes to its queue and triggers if either:
- The queue processed in the last block (to keep the general round-robin
scheduling)
- The queue did not process since `n` blocks (to prevent starvation if
there are too many other queues)

In either situation, it schedules the queue for a streak of three
consecutive blocks, such that it would become:

`| Relay | Relay | Relay | Para(1) | Para(2) | ... | Relay | Relay |
Relay | ... `

It basically transforms the round-robin into an elongated round robin.
Although different strategies can be injected into the pallet at
runtime, this one seems to strike a good balance between general service
level and prioritization.

#### Overview

This PR introduces a new mechanism to capture and report metrics related
to timings of transaction lifecycle events, which are currently not
available. By exposing these timings, we aim to augment transaction-pool
reliability dashboards and extend existing Grafana boards.

A new `unknown_from_block_import_txs` metric is also introduced. It
provides the number of transactions in imported block which are not
known to the node's transaction pool. It allows to monitor alignment of
transaction pools across the nodes in the network.

#### Notes for reviewers
- **[Per-event

which allows to capture both submission timestamps and transaction
status updates. An asynchronous
[`EventsMetricsCollectorTask`](https://github.com/paritytech/polkadot-sdk/blob/8a53992e/substrate/client/transaction-pool/src/fork_aware_txpool/metrics.rs#L503-L526)
processes the metrics-related messages sent by the
`EventsMetricsCollector` and reports the timings of transaction statuses
updates to Prometheus. This task implements event[
de-duplication](https://github.com/paritytech/polkadot-sdk/blob/8a53992e/substrate/client/transaction-pool/src/fork_aware_txpool/metrics.rs#L458)

The goal of this PR is to have the scheduler pallet work on a parachain
which does not produce blocks on a regular schedule, thus can use the
relay chain as a block provider.

Because blocks are not produced regularly, we cannot make the assumption
that block number increases monotonically, and thus have new logic to
handle multiple spend periods passing between blocks.

Requirement: 

instead of using the hard coded system block number. We add an
associated type BlockNumberProvider

# Description

Fixes #7039

The Preservation of transfer method of fungible and fungibles adapters
is changed from Preserve to Expendable. So the behavior of the
TransferAsset will be consistent with the WithdrawAsset function, as in
[fungible](https://github.com/paritytech/polkadot-sdk/blob/f3ab3854

/polkadot/xcm/xcm-builder/src/fungible_adapter.rs#L217)
and [fungibles](https://github.com/paritytech/polkadot-sdk/issues/url)
adapter.

This pull request includes changes to the `fungible_adapter.rs` and
`fungibles_adapter.rs` files in the `polkadot/xcm/xcm-builder`
directory. The main change involves modifying the transfer method to use
the `Expendable` strategy instead of the `Preserve` strategy.

Changes to transfer strategy:

# Description

Resolves #5777

Previously `wasm-builder` used hacks such as `-Zbuild-std` (required
`rust-src` component) and `RUSTC_BOOTSTRAP=1` to build WASM runtime
without WASM features: `sign-ext`, `multivalue` and `reference-types`,
but since Rust 1.84 (will be stable on 9 January, 2025) the situation
has improved as there is new
[`wasm32v1-none`](https://doc.rust-lang.org/beta/rustc/platform-support/wasm32v1-none.html)
target that disables all "post-MVP" WASM features except
`mutable-globals`.

Previously, your `rust-toolchain.toml` looked like this:

```toml
[toolchain]
channel = "stable"
components = ["rust-src"]
targets = ["wasm32-unknown-unknown"]
profile = "default"
```

It should now be updated to something like this:

```toml
[toolchain]
channel = "stable"
targets = ["wasm32v1-none"]
profile = "default"
```

To build the runtime:

```bash
cargo build --package minimal-template-runtime --release
```

## Integration

If you are using Rust 1.84 and above, then install the `wasm32v1-none`
target instead of `wasm32-unknown-unknown` as shown above. You can also
remove the unnecessary `rust-src` component.

Also note the slight differences in conditional compilation:
- `wasm32-unknown-unknown`: `#[cfg(all(target_family = "wasm", target_os
= "unknown"))]`
- `wasm32v1-none`: `#[cfg(all(target_family = "wasm", target_os =
"none"))]`

Avoid using `target_os = "unknown"` in `#[cfg(...)]` or
`#[cfg_attr(...)]` and instead use `target_family = "wasm"` or
`target_arch = "wasm32"` in the runtime code.

## Review Notes

Wasm builder requires the following prerequisites for building the WASM
binary:
- Rust >= 1.68 and Rust < 1.84:
  - `wasm32-unknown-unknown` target
  - `rust-src` component
- Rust >= 1.84:
  - `wasm32v1-none` target
- no more `-Zbuild-std` and `RUSTC_BOOTSTRAP=1` hacks and `rust-src`
component requirements!
