Fixes: https://github.com/paritytech/polkadot-sdk/issues/5122.

This PR extends the existing single core `benchmark_cpu` to also build a
score of the entire processor by spawning `EXPECTED_NUM_CORES(8)`
threads and averaging their throughput.

This is better than simply checking the number of cores, because also
covers multi-tenant environments where the OS sees a high number of
available CPUs, but because it has to share it with the rest of his
neighbours its total throughput does not satisfy the minimum
requirements.

The dry-run shows in `forwarded_xcms` all the messages in the queues at
the time of calling the API.
Each time the API is called, the result could be different.
You could get messages even if you dry-run something that doesn't send a
message, like a `System::remark`.

This PR fixes this by clearing the message queues before doing the
dry-run, so the only messages left are the ones the users of the API
actually care about.

Here are some changes to the `getting-started.sh` scripts we have
advertised on top of the readme.

### Changes to the script

1. Change `echo` to a more portable `printf`.

On my machine, the script printed a literal `\n` string if run with
`bash`.
If I changed it to `echo -e`, then it printed a literal `-e` if run with
`sh`.

Changed it to `printf` which is more portable.

---

2. Template selection

The script proceeded to clone and build the `minimal` template, which is
not always what we want.
Added a selection prompt where the user can select one of the 3
templates, and choose if it should be built&run or not.
The user can also select no template at all - that way, we have a
starter of a dependencies-installation script.

---

3. Added some missing dependencies for some of the systems.

### A workflow testing the script

I propose a workflow, that will test the script using the
[expect](https://core.tcl-lang.org/expect/index) tool.
For each OS mentioned in the script (macOS, Ubuntu, Debian, Arch,
Fedora, OpenSUSE) we go through the script twice, and after that build
and run the template binary.

I'm using docker containers, so we start from scratch and make sure the
scripts installs all required dependencies - with the exception of
macOS, which I can't run from scratch in a container.

The jobs use a selected combination of OSes, shell interpreters (`bash`
or `sh`), and templates.
There is too much combinations to run them all, but I have [run it
once](https://github.com/paritytech-stg/polkadot-sdk/actions/runs/10509533645)
in staging to make sure all pass.

I'm adding a cron schedule because it can break without any code changes
in this repository (e.g. new `latest` release of a container).

start using better type for address, code_hash, and salt in runtime and
the uapi crate

fix https://github.com/paritytech/polkadot-sdk/issues/5575

PR Doc #5443 broke the link checker because it includes a link to this
private repo:

https://github.com/paritytech/devops/issues/3502

This PR adds the `prdoc` folder to the excluded paths of the link
checker to ensure that historical PR Docs do not break the pipeline.

I think this makes sense over whitelisting the github link because we
probably expect that in a long enough time period, links from old PR
docs will start to break, but I don't think we intend to update those
old PR docs, or start whitelisting lots of urls.

This PR will introduce a `BasicProvingTrie` type, which makes it easy to
construct and prove data in a base-16 merkle trie within the runtime.

Data into the merkle trie only require that they implement `Encode` /
`Decode`.

A FRAME compatible `TrieError` was created and added to `DispatchError`.

Expected usage is to construct the merkle trie with all data offline,
and then place only the merkle root of that trie on-chain.

Also offchain, a user is given a compact merkle proof of some data they
want to prove exists on the blockchain.

Then in the runtime, you can call `verify_single_value_proof` or
`verify_proof` with the root, proof, and the keys and values you want to
verify exists in the merkle trie.

Introduce a dynamic proposal deposit mechanism influenced by the total
number of active proposals, with the option to set the deposit to none.

The potential cost (e.g., balance hold) for proposal submission and
storage is determined by the implementation of the `Consideration`
trait. The footprint is defined as `proposal_count`, representing the
total number of active proposals in the system, excluding the one
currently being proposed. This cost may vary based on the proposal
count. The pallet also offers various types to define a cost strategy
based on the number of proposals.

Two new calls are introduced:
- kill(origin, proposal_hash): the cancellation of a proposal,
accompanied by the burning of the associated cost/consideration ticket.
- release_proposal_cost(origin, proposal_hash): the release of the cost
for a non-active proposal.

Additionally change: 
- benchmarks have been upgraded to benchmarks::v2 for collective pallet;
- `ensure_successful` function added to the `Consideration` under
`runtime-benchmarks` feature.

There are basically three commits in this PR. Since all these commits
essentially have no logical changes, I packed them into one PR. Review
by per-commit is recommended.
- The first commit avoids unnecessarily updating the block gap storage
when the value remains unchanged, as discovered when I worked on
https://github.com/paritytech/polkadot-sdk/issues/5406.
- The second commit is purely about format string style changes but
deletes ~10 lines of code, which slightly helps me look into this file
:P
- The third commit is added to avoid the unnecessary block gap update in
`BlockchainDb`.

When using with `polkadot-parachain`, you usually need to specify the
`relay_chain` and `para_id` fields in the chain spec.

With this PR it can be achieved by specifying newly added `--para-id`
and `--relay-chain` command line args, e.g:
```
chain-spec-builder create -r _runtime.wasm  --para-id 100 --relay-chain xxx default
```

This was implemented by simple _json_ blobs merging.

Additionally unit tests covering basic functionality were added.

Also adds a fix for not overwriting the chain spec with the default
config each time, swallowing not standard fields is also fixed.

# Description

Adds retry logic that makes the RPC relay chain interface more reliable
for the cases of a collator connecting to external RPC servers.

Closes #5514 
Closes #4278

Final solution still debated on #5514 , what this PR addresses might
change (e.g. #4278 might require a more advanced approach).

## Integration

Users that start collators should barely observe differences based on
this logic, since the retry logic applies only in case the collators
fail to connect to the RPC servers. In practice I assume the RPC servers
are already live before starting collators, and the issue isn't visible.

## Review Notes

The added retry logic is for retrying the connection to the RPC servers
(which can be multiple). It is at the level of the
cumulus/client/relay-chain-rpc-interface module, but more specifically
relevant to the RPC clients logic (`ClientManager`). The retry logic is
not configurable, it tries to connect to the RPC client for 5 times,
with an exponential backoff in between each iteration starting with 1
second wait time and ending with 16 seconds. The same logic is applied
in case an existing connection to an RPC is dropped. There is a
`ReconnectingWebsocketWorker` who ensures there is connectivity to at
least on RPC node, and the retry logic makes this stronger by insisting
on trying connections to the RPC servers list for 5 times.

## Testing

- This was tested manually by starting zombienet natively based on
[006-rpc_collator_builds_blocks.toml](https://github.com/paritytech/polkadot-sdk/blob/master/cumulus/zombienet/tests/0006-rpc_collator_builds_blocks.toml)
and observing collators don't fail anymore:

```bash
zombienet -l text --dir zbn-run -f --provider native spawn polkadot-sdk/cumulus/zombienet/tests/0006-rpc_collator_builds_blocks.toml
```

- Added a unit test that exercises the retry logic for a client
connection to a server that comes online in 10 seconds. The retry logic
can wait for as long as 30 seconds, but thought that it is too much for
a unit test. Just being conscious of CI time if it runs this test, but I
am happy to see suggestions around it too. I am not that sure either it
runs in CI, haven't figured it out entirely yet. The test can be
considered an integration test too, but it exercises crate internal
implementation, not the public API.

The https://github.com/paritytech/polkadot-sdk/issues/5512 has surfaced
that we reported a `BestBlock` event for a block not previously reported
via `NewBlock`.

This is because of a race between:
- the stream of events that announces new blocks
- `self.client.info().best_block`

It is possible that `client.info()` contains newer information than the
information polled from the block stream (that may be lagging).

To mitigate this, instead of relying on the client's info use the last
finalized block to emit a new event.

There are two cases when a new best block event is emitted:
- The best block is in the pruned list and is reported immediately
- The best block is not a descendant of the last finalized block 

Closes: https://github.com/paritytech/polkadot-sdk/issues/5512

Before we only supported CREATE2 semantics for contract address

This PR switches the runtime to the new receipts format (vstaging
primitives). I've implemented `From` to convert from new primitives to
`v7` primitives and used them in the node runtime api client
implementation. Until we implement the support in the node, it will
continue e to use the v7 primitives but the runtime apis already use the
new primitives.


An expected downside of RFC103 is decoding V2 receipts shows garbage
values if the input is V1:

Created a new @paritytech/smart-contracts team that is now referenced in
the review bot config and CODEOWNERS file. Also excluded the new pallet
in the other review bot rules.

Relates to:
https://github.com/paritytech/parity-bridges-common/issues/2451
Closes: https://github.com/paritytech/parity-bridges-common/issues/2500

## Summary

Now, the bridging pallet supports only static lanes, which means lanes
that are hard-coded in the runtime files. This PR fixes that and adds
support for dynamic, also known as permissionless, lanes. This means
that allowed origins (relay chain, sibling parachains) can open and
close bridges (through BridgeHubs) with another bridged (substrate-like)
consensus using just `xcm::Transact` and `OriginKind::Xcm`.

_This PR is based on the migrated code from the Bridges V2
[branch](https://github.com/paritytech/polkadot-sdk/pull/4427) from the
old `parity-bridges-common`
[repo](https://github.com/paritytech/parity-bridges-common/tree/bridges-v2)._

## Explanation

Please read
[bridges/modules/xcm-bridge-hub/src/lib.rs](https://github.com/paritytech/polkadot-sdk/blob/149b0ac2

/bridges/modules/xcm-bridge-hub/src/lib.rs#L17-L136)
to understand how managing bridges works. The basic concepts around
`BridgeId` and `LaneId` are also explained there.


## TODO

- [x] search and fix for comment: `// TODO:(bridges-v2) - most of that
stuff was introduced with free header execution:
https://github.com/paritytech/polkadot-sdk/pull/4102` - more info in the

- [x] regenerate all relevant weights for BH/AH runtimes
- [ ] regenerate default weights for bridging pallets e.g.
`modules/messages/src/weights.rs`
- [ ] add benchmarks for `xcm-bridge-hub` pallet

**testing:**
- [ ] add xcm-emulator tests for Rococo/Penpal to Westend/Penpal with
full opening channel and sending/receiving `xcm::Transact`

**migrations:**
- [x] add migrations for BridgeHubRococo/Westend
https://github.com/paritytech/parity-bridges-common/issues/2794 (to be
reusable for P/K bridge)
  - [x] check also storage migration, if needed for pallets
  - [ ] migration for XCM type (optional)
  - [x] migration for static lanes to the dynamic (reuse for fellows)

- [ ] check congestion around `LocalXcmChannelManager` and
`OutboundLanesCongestedSignals` impls -

There is a race condition when a validator sends its heads to the
collator, but the collator doesn't yet know these heads. Before it is
aware of these heads by importing the block(s), any collation registered
on the collator is not announced to the validators. The collations
aren't advertised, because the collator doesn't know yet that these
heads of the validator are descendants of the collations relay parent.

The solution is to store these unknown heads of the validators and to
handle them when the collator updates its own view.

This improves `sc-service` API by not requiring the whole
`&Configuration`, using specific configuration options instead.
`RpcConfiguration` was also extracted from `Configuration` to group all
RPC options together.

We don't use Substrate's CLI and would rather not use `Configuration`
either, but some key public functions require it even though they
ignored most of the fields anyway.

`RpcConfiguration` is very helpful not just for consolidation of the
fields, but also to finally make RPC optional for our use case, while
Substrate still runs RPC server on localhost even if listening address
is explicitly set to `None`, which is annoying (and I suspect there is a
reason for it, so didn't want to change the default just yet).

While this is a breaking change, most developers will not notice it if
they use higher-level APIs.

# Context

Fees can already be paid in other assets locally thanks to the Trader
implementations we have.
This doesn't work when sending messages because delivery fees go through
a different mechanism altogether.
The idea is to fix this leveraging the `AssetExchanger` config item
that's able to turn the asset the user wants to pay fees in into the
asset the router expects for delivery fees.

# Main addition

An adapter was needed to use `pallet-asset-conversion` for exchanging
assets in XCM.
This was created in
https://github.com/paritytech/polkadot-sdk/pull/5130.

The XCM executor was modified to use `AssetExchanger` (when available)
to swap assets to pay for delivery fees.

## Limitations

We can only pay for delivery fees in different assets in intermediate
hops. We can't pay in different assets locally. The first hop will
always need the native token of the chain (or whatever is specified in
the `XcmRouter`).
This is a byproduct of using the `BuyExecution` instruction to know
which asset should be used for delivery fee payment.
Since this instruction is not present when executing an XCM locally, we
are left with this limitation.
To illustrate this limitation, I'll show two scenarios. All chains
involved have pools.

### Scenario 1

Parachain A --> Parachain B

Here, parachain A can use any asset in a pool with its native asset to
pay for local execution fees.
However, as of now we can't use those for local delivery fees.
This means transfers from A to B need some amount of A's native token to
pay for delivery fees.

### Scenario 2

Parachain A --> Parachain C --> Parachain B

Here, Parachain C's remote delivery fees can be paid with any asset in a
pool with its native asset.
This allows a reserve asset transfer between A and B with C as the
reserve to only need A's native token at the starting hop.
After that, it could all be pool assets.

## Future work

The fact that delivery fees go through a totally different mechanism
results in a lot of bugs and pain points.
Unfortunately, this is not so easy to solve in a backwards compatible
manner.
Delivery fees will be integrated into the language in future XCM
versions, following
https://github.com/polkadot-fellows/xcm-format/pull/53.

Old PR: https://github.com/paritytech/polkadot-sdk/pull/4375.

# Prerequisite 
This is part of the work to further optimize the approval subsystems, if
you want to understand the full context start with reading
https://github.com/paritytech/polkadot-sdk/pull/4849#issue-2364261568,

# Description
This PR contain changes, so that the crypto checks are performed by the
approval-distribution subsystem instead of the approval-voting one. The
benefit for these, is twofold:
1. Approval-distribution won't have to wait every single time for the
approval-voting to finish its job, so the work gets to be pipelined
between approval-distribution and approval-voting.

2. By running in parallel multiple instances of approval-distribution as
described here
https://github.com/paritytech/polkadot-sdk/pull/4849#issue-2364261568,
this significant body of work gets to run in parallel.

## Changes:
1. When approval-voting send `ApprovalDistributionMessage::NewBlocks` it
needs to pass the core_index and candidate_hash of the candidates.
2. ApprovalDistribution needs to use `RuntimeInfo` to be able to fetch
the SessionInfo from the runtime.
3. Move `approval-voting` logic that checks VRF assignment into
`approval-distribution`
4. Move `approval-voting` logic that checks vote is correctly signed
into `approval-distribution`
5. Plumb `approval-distribution` and `approval-voting` tests to support
the new logic.

## Benefits
Even without parallelisation the gains are significant, for example on
my machine if we run approval subsystem bench for 500 validators and 100
cores and trigger all 89 tranches of assignments and approvals, the
system won't fall behind anymore because of late processing of messages.
```
Before change
Chain selection approved  after 11500 ms hash=0x0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a

After change

Chain selection approved  after 5500 ms hash=0x0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a
```

## TODO:
- [x] Run on versi.
- [x] Update parachain host documentation.
