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

`EventsMetricsCollector`](https://github.com/paritytech/polkadot-sdk/blob/8a53992e/substrate/client/transaction-pool/src/fork_aware_txpool/metrics.rs#L353-L358)
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)
using a `HashMap` of
[`TransactionEventMetricsData`](https://github.com/paritytech/polkadot-sdk/blob/8a53992e/substrate/client/transaction-pool/src/fork_aware_txpool/metrics.rs#L424-L435)

[compute
timings](https://github.com/paritytech/polkadot-sdk/blob/8a53992e/substrate/client/transaction-pool/src/fork_aware_txpool/metrics.rs#L489-L495).
Transaction-related items are removed when transaction's final status is
[reported](https://github.com/paritytech/polkadot-sdk/blob/8a53992e/substrate/client/transaction-pool/src/fork_aware_txpool/metrics.rs#L496).
- Transaction submission timestamp is reusing the timestamp of
`TimedTransactionSource` kept in mempool. It is reported to
`EventsMetricsCollector` in
[`submit_at`](https://github.com/paritytech/polkadot-sdk/blob/8a53992e/substrate/client/transaction-pool/src/fork_aware_txpool/fork_aware_txpool.rs#L735)
and
[`submit_and_watch`](https://github.com/paritytech/polkadot-sdk/blob/8a53992e/substrate/client/transaction-pool/src/fork_aware_txpool/fork_aware_txpool.rs#L836)
methods of `ForkAwareTxPool`.
- Transaction updates are reported to `EventsMetricsCollector` from
`MultiViewListener`
[task](https://github.com/paritytech/polkadot-sdk/blob/8a53992e/substrate/client/transaction-pool/src/fork_aware_txpool/multi_view_listener.rs#L494).
This allows to gather metrics for _watched_ and _non-watched_
transactions (what enables metrics on non-rpc-enabled collators).
- New metric

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...

Let's burry out the old `RUSTC_BOOTSTRAP` hack. This is required when
you don't use `rustup` which automatically switches to the nightly
toolchain when it detects nightly CLI args.

Recently there were some requests to build and deploy a binary, for
example `polkadot`, in the `release` or `production` profile to do some
testing.
So far we had only a
[release](https://github.com/paritytech/polkadot-sdk/blob/master/.github/workflows/release-20_build-rc.yml)
pipeline that could do it in the GitHub but to use it, there was a lot
of extra overhead needed.
This pipeline should simplify this case and give a possibility to build
a binary in desired profile from any branch for the testing purposes.
Something similar to what we have for runtimes in the [srtool
repo](https://github.com/paritytech/srtool/actions/workflows/manual.yml)
It won't be used in any release activities though.

There is a small issue on restart, where if finality is lagging across
session boundary and the validator restarts, then the validator won't be
able to contribute anymore with assginments/approvals and gossiping for
the blocks from the previous session, because after restart it builds
the Topology only for the new session, so without a topology it won't be
able to distribute assignments and approvals because everything in
`approval-distribution` is gated on having a topology for the block.

The fix is to also keep track of the last finalized block and its
session and if it is different from the list of encountered sessions,
build its topology and send it to the rest of subsystems.

- Closes https://github.com/paritytech/license-scanner/issues/44
- Silent because only comments are changed in the crates.

## What's inside

First, we change the file traversal mechanism from shell globbing to
walking through files which happens inside the `license-scanner` - so it
has knowledge about directory structure and can correlate files with
corresponding Cargo manifest.

Next, added `MIT-0` and `Unlicense` to the allowed list of licenses.
`Unlicense` appears only once across {Substrate,Cumulus,Polkadot} - in
`penpal-runtime`.

Finally, updated headers in files that do not match the corresponding
manifest license.
