Fix the broker pallet auto-renew benchmarks which have been broken since
#4424, yielding `Weightless` due to some prices being set too low, as
reported in #6474.

Upon further investigation it turned out that the auto-renew
contribution to `rotate_sale` was always failing but the error was
mapped. This is also fixed at the cost of a bit of setup overhead.

Fixes #6474

`InitiateTransfer`, the new instruction introduced in XCMv5, allows
preserving the origin after a cross-chain transfer via the usage of the
`AliasOrigin` instruction. The receiving chain needs to be configured to
allow such this instruction to have its intended effect and not just
throw an error.

In this PR, I add the alias rules specified in the [RFC for origin
preservation](https://github.com/polkadot-fellows/RFCs/blob/main/text/0122-alias-origin-on-asset-transfers.md)
to westend chains so we can test these scenarios in the testnet.

The new scenarios include:
- Sending a cross-chain transfer from one system chain to another and
doing a Transact on the same message (1 hop)
- Sending a reserve asset transfer from one chain to another going
through asset hub and doing Transact on the same message (2 hops)

The updated chains are:
- Relay: added `AliasChildLocation`
- Collectives: added `AliasChildLocation` and
`AliasOriginRootUsingFilter<AssetHubLocation, Everything>`
- People: added `AliasChildLocation` and
`AliasOriginRootUsingFilter<AssetHubLocation, Everything>`
- Coretime: added `AliasChildLocation` and
`AliasOriginRootUsingFilter<AssetHubLocation, Everything>`

AssetHub already has `AliasChildLocation` and doesn't need the other
config item.
BridgeHub is not intended to be used by end users so I didn't add any
config item.
Only added `AliasChildOrigin` to the relay since we intend for it to be
used less.

## Description

With [permissionless lanes
PR#4949](https://github.com/paritytech/polkadot-sdk/pull/4949), the
congestion mechanism based on sending
`Transact(report_bridge_status(is_congested))` from
`pallet-xcm-bridge-hub` to `pallet-xcm-bridge-hub-router` was replaced
with a congestion mechanism that relied on monitoring XCMP queues.
However, this approach could cause issues, such as suspending the entire
XCMP queue instead of isolating the affected bridge. This PR reverts
back to using `report_bridge_status` as before.

Last feature we wanted for V5, changing `SetAssetClaimer` to be just one
of many possible "hints" that you can specify at the beginning of your
program to change its behaviour.

This makes it easier to add new hints in the future and have barriers
accept them.

Closes: https://github.com/paritytech/polkadot-sdk/issues/6585

Removing the `require_weight_at_most` parameter in V5 Transact had only
one problem. Converting a message from V5 to V4 to send to chains that
didn't upgrade yet. The conversion would not know what weight to give to
the Transact, since V4 and below require it.

To fix this, I added back the weight in the form of an `Option<Weight>`
called `fallback_max_weight`. This can be set to `None` if you don't
intend to deal with a chain that hasn't upgraded yet. If you set it to
`Some(_)`, the behaviour is the same. The plan is to totally remove this
in V6 since there will be a good conversion path from V6 to V5.

* Add a bunch of differential tests to ensure that responses from
eth-rpc matches the one from `geth`
- These
[tests](https://github.com/paritytech/polkadot-sdk/blob/pg/fix-geth-diff/substrate/frame/revive/rpc/examples/js/src/geth-diff.test.ts)
are not run in CI for now but can be run locally with
```bash
cd revive/rpc/examples/js
bun test
```

* EVM RPC server will not fail gas_estimation if no gas is specified, I
updated pallet-revive to add an extra `skip_transfer` boolean check to
replicate this behavior in our pallet

* `eth_transact` and `bare_eth_transact` api have been updated to use
`GenericTransaction` directly as this is what is used by
`eth_estimateGas` and `eth_call`

## TODO

- [ ]  Add tests the new `skip_transfer` flag

The `query_weight_to_asset_fee` function was trying to convert versions
by using `try_as`, this function [doesn't convert from a versioned to a
concrete
type](https://github.com/paritytech/polkadot-sdk/blob/0156ca8f/polkadot/xcm/src/lib.rs#L131).
This would cause all calls with a lower version to fail.

The correct function to use is the good old
[try_into](https://github.com/paritytech/polkadot-sdk/blob/0156ca8f

/polkadot/xcm/src/lib.rs#L184).
Now those calls work :)

Step in https://github.com/paritytech/polkadot-sdk/issues/3268

This PR adds the ability for these pallets to specify their source of
the block number. This is useful when these pallets are migrated from
the relay chain to a parachain and vice versa.

This change is backwards compatible:
1. If the `BlockNumberProvider` continues to use the system pallet's
block number
2. When a pallet deployed on the relay chain is moved to a parachain,
but still uses the relay chain's block number

However, we would need migrations if the deployed pallets are upgraded
on an existing parachain, and the `BlockNumberProvider` uses the relay
chain block number.

This PR includes:  
- Refactored integrity tests to support standalone deployment of
`pallet-bridge-messages`.
- Refactored the `open_and_close_bridge_works` test case to support
multiple scenarios, such as:
  1. A local chain opening a bridge.  
  2. Sibling parachains opening a bridge.  
  3. The relay chain opening a bridge.  
- Previously, we added instance support for `pallet-bridge-relayer` but
overlooked updating the `DeliveryConfirmationPaymentsAdapter`.

Closes #2082

change send xcm to use `xcm::executor::FeeManager` to determine if the
sender should be charged.

I had to change the `FeeManager` of the penpal config to ensure the same
test behaviour as before. For the other tests, I'm using the
`FeeManager` from the `xcm::executor::FeeManager` as this one is used to
check if the fee can be waived on the charge fees method.

Remove `sp_runtime::RuntimeString` and replace with `Cow<'static, str>` or `String` depending on use case (#5693)

# Description

As described in https://github.com/paritytech/polkadot-sdk/issues/4001
`RuntimeVersion` was not encoded consistently using serde. Turned out it
was a remnant of old times and no longer actually needed. As such I
removed it completely in this PR and replaced with `Cow<'static, str>`
for spec/impl names and `String` for error cases.

Fixes https://github.com/paritytech/polkadot-sdk/issues/4001.

## Integration

For downstream projects the upgrade will primarily consist of following
two changes:
```diff
#[sp_version::runtime_version]
pub const VERSION: RuntimeVersion = RuntimeVersion {
-	spec_name: create_runtime_str!("statemine"),
-	impl_name: create_runtime_str!("statemine"),
+	spec_name: alloc::borrow::Cow::Borrowed("statemine"),
+	impl_name: alloc::borrow::Cow::Borrowed("statemine"),
```

		fn dispatch_benchmark(
			config: frame_benchmarking::BenchmarkConfig

Remove references of now defunct Wococo network.

The XCM `NetworkId::Wococo` will also be removed with [XCMv5
PR](https://github.com/paritytech/polkadot-sdk/pull/4826)

Replace `GlobalConsensusEthereumConvertsFor` with
`EthereumLocationsConverterFor` that allows `Location` to `AccountId`
conversion for the Ethereum network root as before, but also for
Ethereum contracts and accounts.

The new converter only matches explicit `parents: 2` Ethereum locations,
meaning it should be used only on/by parachains.

This PR removes the `transfer` syscall and changes balance transfers to
make the existential deposit (ED) fully transparent for contracts.

The `transfer` API is removed since there is no corresponding EVM opcode
and transferring via a call introduces barely any overhead.

We make the ED transparent to contracts by transferring the ED from the
call origin to nonexistent accounts. Without this change, transfers to
nonexistant accounts will transfer the supplied value minus the ED from
the contracts viewpoint, and consequentially fail if the supplied value
lies below the ED. Changing this behavior removes the need for contract
code to handle this rather annoying corner case and aligns better with
the EVM. The EVM charges a similar deposit from the gas meter, so
transferring the ED from the call origin is practically the same as the
call origin pays for gas.

The goal of this PR is to have the treasury 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.

This PR refactors `pallet-identity` to decouple usernames from
identities.

Main changes in this PR:
- Separate usernames from identities in storage, allowing for correct
deposit accounting
- Introduce the option for username authorities to put up a deposit to
issue a username
- Allow authorities to remove usernames by declaring the intent to do
so, then removing the username after the grace period expires
- Refactor the authority storage to be keyed by suffix rather than owner
account.
- Introduce the concept of a system provider for a username, different
from a governance allocation, allowing for usernames set by the system
and not a specific authority
- Implement multi-block migration to enable all of the changes described
above

zombienet testing

`ForeignCreatorsSovereignAccountOf` is used by `ForeignCreators` filter
to convert location to `AccountId`, _after_ `ForeignCreators::IsForeign`
filter passes for an (asset, location) pair.

The `IsForeign` filter is the actual differentiator, so if a location
passes it, we should support converting it to an `AccountId`.

As such, this commit replaces `ForeignCreatorsSovereignAccountOf`
converter with the more general `LocationToAccountId` converter.

Fixes #5576

This allows contracts to be used with an AccountId32 through normal
extrinsics and not only through the eth compat layer. It works by adding
a new extrinsic `map_account` that lets people register their
AccountId32.

This PR backports regular version bumps and prdocs reordering from the
current stable release back to master

Fixed in Polkadot and Kusama in
https://github.com/polkadot-fellows/runtimes/pull/434 and this PR just
adds to testnets.

We can handle a maximum of 28 assignments inside one XCM, while it's
possible to have 80 (if a region is interlaced 79 times).
This can be chunked on the coretime chain side but currently the
scheduler on the relay makes assumptions that means we can't send more
than one chunk for a given core.

This just truncates the additional assignments until we can extend the
relay to support this. This means that the first 27 assignments are
taken, the final 28th is used to pad with idle to complete the mask (the
relay also assumes that every schedule is complete). Any other
assignments are dropped.
