This PR contains improved test cases that rely on the governance
location as preparation for AHM to capture the state as it is.
It introduces `execute_as_governance_call`, which can be configured with
various governance location setups instead of the hard-coded
`Location::parent()`.

Additionally, it adds a test for `authorize_upgrade` to all SP testnets.


## TODO
- [x] rewrite all tests using
`RuntimeHelper::<Runtime>::execute_as_governance` (because it is using
hard-coded `Location::parent()`) to use
`RuntimeHelper::<Runtime>::execute_as_governance_call`

## Follow-up
- [ ] add similar test for westend-runtime
- [ ] add test that ensure xcm-executor adds `ClearOrigin` before all
side-effect sent to different chain

There were already previous efforts to remove the contracts-rococo
chain, see #5471, which was done as a response to this comment
https://github.com/paritytech/polkadot-sdk/pull/5288#discussion_r1711157476.

This PR intends to fix the parts that were overlooked back then, and
remove all traces of contracts-rococo as it is intended to be replaced
by a new testnet including pallet-revive.

removed run-relay references removed in PR #7549

`sc-cli` brings rocksdb dependency into frame-benchmarking-cli when used
with `default-features = false`.
This PR makes rocksdb deps optional that sc-cli brings in some of the
crates. I think I covered all the crates that depend on sc-cli but
please let me know if I missed any.

Fixes: https://github.com/paritytech/polkadot-sdk/issues/3793

# Description

Fixes #7413

## Integration

This PR updates the `DryRunApi`. The signature of the `dry_run_call` is
changed, and the XCM version of the return values of `dry_run_xcm` now
follows the version of the input XCM program.

## Review Notes

* **The `DryRunApi` is modified**
* **Added the `Router::clear_messages` to `dry_run_xcm` common
implementation**
* **Fixed the xcmp-queue's Router's clear_messages: channels details'
first_index and last_index are reset when clearing**
* **The MIN_XCM_VERSION is added**
* The common implementation in the `pallet-xcm` is modified accordingly
* The `DryRunApi` tests are modified to account for testing old XCM
versions
* The implementation from the `pallet-xcm` is used where it was not used
(including the `DryRunApi` tests)
* All the runtime implementations are modified according to the Runtime
API change

# Description

Adds support for the upcoming Ethereum Electra upgrade, while
maintaining backwards compatibility for the current Deneb fork.

## Integration

Relayers should be updated to send updated Electra consensus data
structures.

## Review Notes

The [Ethereum Electra hard-fork
consensus](https://github.com/ethereum/consensus-specs/blob/dev/specs/electra/light-client/sync-protocol.md)
changes affecting the Ethereum light client are mainly isolated to the
[Generalized
Indexes](https://github.com/protolambda/eth2.0-ssz/blob/master/specs/navigation/generalized_indices.md)
of data structures changing. Before Electra, these values were hardcoded
in config. For Electra, these values change and needed to the updated.
Methods were added to return the correct g-index for the current fork
version.

Data structures used by the Ethereum client did not change in this
hard-fork. The BeaconState container has been updated with additional
changes, but because the on-chain code does not reference the
BeaconState directly (only indirectly through merkle proofs), it is not
a concern. Off-chain relayers use the BeaconState to generate proofs,
and so the relayer code has been updated accordingly.

Various pallet-revive improvements

- add check for precompiles addresses,
So we can easily identify which one are being called and not supported
yet

- fixes debug_call for revert call
If a call revert we still want to get the traces for that call, that
matches geth behaviors, diff tests will be added to the test suite for
this

- fixes traces for staticcall
The call type was not always being reported properly.

Ref https://github.com/paritytech/ci_cd/issues/1107

We mainly need that so that we can finally compile the `pallet_revive`
fixtures on stable. I did my best to keep the commits focused on one
thing to make review easier.

All the changes are needed because rustc introduced more warnings or is
more strict about existing ones. Most of the stuff could just be fixed
and the commits should be pretty self explanatory. However, there are a
few this that are notable:

## `non_local_definitions `

A lot of runtimes to write `impl` blocks inside functions. This makes
sense to reduce the amount of conditional compilation. I guess I could
have moved them into a module instead. But I think allowing it here
makes sense to avoid the code churn.

## `unexpected_cfgs`

The FRAME macros emit code that references various features like `std`,
`runtime-benchmarks` or `try-runtime`. If a create that uses those
macros does not have those features we get this warning. Those were
mostly when defining a `mock` runtime. I opted for silencing the warning
in this case rather than adding not needed features.

For the benchmarking ui tests I opted for adding the `runtime-benchmark`
feature to the `Cargo.toml`.

## Failing UI test

I am bumping the `trybuild` version and regenerating the ui tests. The
old version seems to be incompatible. This requires us to pass
`deny_warnings` in `CARGO_ENCODED_RUSTFLAGS` as `RUSTFLAGS` is ignored
in the new version.

## Removing toolchain file from the pallet revive fixtures

This is no longer needed since the latest stable will compile them fine
using the `RUSTC_BOOTSTRAP=1`.

Add the sudo pallet to coretime-westend, allowing use in
development/testing. Previously the coretime-rococo runtime was used in
situations like this, but since Rococo is now gone this can be used
instead.

No sudo key is added to Westend storage with this PR, since it's likely
that any updates will continue to be done over XCM. If this is something
that is wanted the key can be set via XCM.

## Integration

Downstream projects need to benchmark the weight for the remove_lease()

## Review Notes

Mentorship is requested to ensure this is implemented correctly.

The lease is removed from state using the TaskId as a key. Is this
sufficient. Does the extrinsic need to do anything else?

Relates to: https://github.com/paritytech/polkadot-sdk/issues/7274

## Description

The PR enhances the `pallet-bridge-rewards` by making it generic over
the `RewardKind` type (previously hardcoded as `RewardsAccountParams`).
This modification allows the pallet to support multiple reward types
(e.g., P/K bridge, Snowbridge), increasing its flexibility and
applicability across various bridge scenarios.

Other pallets can register rewards using `bp_relayers::RewardLedger`,
which is implemented by the rewards pallet. The runtime can then be
configured with different mechanisms for paying/claiming rewards via
`bp_relayers::PaymentProcedure` (e.g., see the `pub struct
BridgeRewardPayer;` implementation for BridgeHubWestend).

## Follow-up  
The removed balances/rewards statistics from the complex relay (no
longer used) will eventually be reintroduced or fixed in the standalone
relayers via
https://github.com/paritytech/parity-bridges-common/issues/3004#issuecomment-2401634589.

XCM: Deny barrier checks for nested XCMs with specific instructions to be executed on the local chain (#7200)

Resolves (partially):
https://github.com/paritytech/polkadot-sdk/issues/7148
Depends on: https://github.com/paritytech/polkadot-sdk/pull/7169

# Description

This PR addresses partially #7148 (Problem 2) and ensures the proper
checking of nested local instructions. It introduces a new barrier -
`DenyRecursively` - to provide more refined control over instruction
denial. The main change is the replacement of `DenyThenTry<Deny, Allow>`
with `DenyThenTry<DenyRecursively<Deny>, Allow>` which handles both
top-level and nested local instructions by applying allow condition
after denial.

For context and additional information, please refer to [_Problem 2 -
Barrier vs nested XCM
validation_](https://github.com/paritytech/polkadot-sdk/issues/7148).

# TODO
- [x] Evaluate PoC, more details at #7351:
    - **DenyNestedXcmInstructions**: Keep it as it is and be explicit:
        1. Name the Deny barriers for the top level.
2. Name the Deny barrier for nested with `DenyInstructionsWithXcm`.
- **DenyThenTry<DenyInstructionsWithXcm<Deny>, Allow>**: Alternatively,
hard-code those three instructions in `DenyThenTry`, so we wouldn’t need
`DenyInstructionsWithXcm`. However, this approach wouldn’t be as
general.
- **DenyInstructionsWithXcmFor**: Another possibility is to check
`DenyInstructionsWithXcm::Inner` for the actual `message`, so we don’t
need duplication for top-level and nested (not sure, maybe be explicit
is good thing) - see _Problem2 - example_. Instead of this:
   ```

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`.

Returning an iterator in `TracksInfo::tracks()` instead of a static
slice allows for more flexible implementations of `TracksInfo` that can
use the chain storage without compromising a lot on the
performance/memory penalty if we were to return an owned `Vec` instead.

# 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.

Resolves #6000

## 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

This PR ensure that only valid syntax is uses inside the `Cargo.toml`. 

## Integration

Not sure if worth backporting. Came across this when trying to package
`try-runtime-cli`.

## Review Notes

It should be obvious that this is not valid syntax. I am not able to add
labels and doubt this requires a prdoc.

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.

Follow up from
https://github.com/paritytech/polkadot-sdk/pull/6362#issuecomment-2629744365

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

- 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.

Apply some fixes to properly estimate ethereum tx fees:

- Set the `extension_weight` on the dispatch_info to properly calculate
the fee with pallet_transaction_payment
- Expose the gas_price through Runtime API, just in case we decide to
tweak the value in future updates, it should be read from the chain
rather than be a shared constant exposed by the crate
- add a `evm_gas_to_fee` utility function to properly convert gas to
substrate fee
- Fix some minor gas encoding for edge cases

# Description

Copy pasted the `parachain-template-node` offchain worker setup to
omni-node-lib for both aura and manual seal nodes.

Closes #7447 

## Integration

Enabled offchain workers for both `polkadot-omni-node` and
`polkadot-parachain` nodes. This would allow executing offchain logic in
the runtime and considering it on the node side.

This PR will make omni-node dev-mode once again compatible with older
runtimes.

The changes introduced in
https://github.com/paritytech/polkadot-sdk/pull/6825 changed constraints
that are enforced in the runtime. For normal chains this should work
fine, since we have real parameters there, like relay chain slots and
parachain slots.

For these manual seal parameters we need to respect the constraints,
while faking all the parameters. This PR should fix manual seal in
omni-node to work with runtime build before and after
https://github.com/paritytech/polkadot-sdk/pull/6825 (I tested that).

In the future, we should look into improving the parameterization here,
possibly by introducing proper aura pre-digests so that the parachain
slot moves forward. This will require quite a bit of refactoring on the
manual seal node side however. Issue:
https://github.com/paritytech/polkadot-sdk/issues/7453

Also, the dev chain spec in parachain template is updated. This makes it
work with stable2412-1 and master omni-node. Once the changes here are
backported and in a release, all combinations will work again.

fixes https://github.com/paritytech/polkadot-sdk/issues/7341
