This PR has small addition to the db package version. As `cargodeb`
takes the version from the `*.toml` file, this PR adds an extra flag to
the `cargodeb` command so that the version of the deb package matches
the `polkadot` node version.

Fixes https://github.com/paritytech/polkadot-sdk/issues/5530

This PR introduces the removal of backing jobs that have been back
pressured for longer than `allowedAncestryLen`, as these candidates are
no longer viable.

It is reasonable to expect a result for a backing job execution within
`allowedAncestryLen` blocks. Therefore, we set the job TTL as a relay
block number and synchronize the validation host by sending activated
leaves.

This PR ensures that external addresses with different PeerIDs are not
propagated to the higher layer of the network code.

While at it, this ensures that libp2p only adds the `/p2p/peerid` part
to the discovered address if it does not contain it already.

# Description

This is a continuation of
https://github.com/paritytech/polkadot-sdk/pull/5666 that finally fixes
https://github.com/paritytech/polkadot-sdk/issues/5333.

This should allow developers to create custom syncing strategies or even
the whole syncing engine if they so desire. It also moved syncing engine
creation and addition of corresponding protocol outside
`build_network_advanced` method, which is something Bastian expressed as
desired in
https://github.com/paritytech/polkadot-sdk/issues/5#issuecomment-1700816458

Here I replaced strategy-specific types and methods in `SyncingStrategy`
trait with generic ones. Specifically `SyncingAction` is now used by all
strategies instead of strategy-specific types with conversions.
`StrategyKey` was an enum with a fixed set of options and now replaced
with an opaque type that strategies create privately and send to upper
layers as an opaque type. Requests and responses are now handled in a
generic way regardless of the strategy, which reduced and simplified
strategy API.

`PolkadotSyncingStrategy` now lives in its dedicated module (had to edit
.gitignore for this) like other strategies.

`build_network_advanced` takes generic `SyncingService` as an argument
alongside with a few other low-level types (that can probably be
extracted in the future as well) without any notion of specifics of the
way syncing is actually done. All the protocol and tasks are created
outside and not a part of the network anymore. It still adds a bunch of
protocols like for light client and some others that should eventually
be restructured making `build_network_advanced` just building generic
network and not application-specific protocols handling.

## Integration

Just like https://github.com/paritytech/polkadot-sdk/pull/5666
introduced `build_polkadot_syncing_strategy`, this PR introduces
`build_default_block_downloader`, but for convenience and to avoid
typical boilerplate a simpler high-level function
`build_default_syncing_engine` is added that will take care of creating
typical block downloader, syncing strategy and syncing engine, which is
what most users will be using going forward. `build_network` towards the
end of the PR was renamed to `build_network_advanced` and
`build_network`'s API was reverted to
pre-https://github.com/paritytech/polkadot-sdk/pull/5666, so most users
will not see much of a difference during upgrade unless they opt-in to
use new API.

## Review Notes

For `StrategyKey` I was thinking about using something like private type
and then storing `TypeId` inside instead of a static string in it, let
me know if that would preferred.

The biggest change happened to requests that different strategies make
and how their responses are handled. The most annoying thing here is
that block response decoding, in contrast to all other responses, is
dependent on request. This meant request had to be sent throughout the
system. While originally `Response` was `Vec<u8>`, I didn't want to
re-encode/decode request and response just to fit into that API, so I
ended up with `Box<dyn Any + Send>`. This allows responses to be truly
generic and each strategy will know how to downcast it back to the
concrete type when handling the response.

Import queue refactoring was needed to move `SyncingEngine` construction
out of `build_network` that awkwardly implemented for `SyncingService`,
but due to `&mut self` wasn't usable on `Arc<SyncingService>` for no
good reason. `Arc<SyncingService>` itself is of course useless, but
refactoring to replace it with just `SyncingService` was unfortunately
rejected in https://github.com/paritytech/polkadot-sdk/pull/5454

As usual I recommend to review this PR as a series of commits instead of
as the final diff, it'll make more sense that way.

### Overview 

Introduces similar checker struct to `CheckTraitDecls` in
`decl_runtime_apis!` - `CheckTraitImpls`. Overrides
`visit::visit_type_path` to detect usage of `Self` as a type argument
within the scope of `impl_runtime_apis!`.

**Note**: only prevents the usage of `Self` as a type argument in an
angle bracket `<>`, as it is the only use case that fails to compile.
For example, the code
[below](https://github.com/paritytech/polkadot-sdk/blob/master/cumulus/parachains/runtimes/bridge-hubs/bridge-hub-westend/src/lib.rs#L1002)
compiles fine:

```rs
impl BridgeMessagesConfig<WithBridgeHubRococoMessagesInstance> for Runtime {
  fn is_relayer_rewarded(relayer: &Self::AccountId) -> bool {
	  let bench_lane_id = <Self as BridgeMessagesConfig<WithBridgeHubRococoMessagesInstance>>::bench_lane_id();
	  // ...
```

### Result

Given a block of code like this:

```rs
impl_runtime_apis! {
	impl apis::Core<Block> for Runtime {
		fn initialize_block(header: &HeaderFor<Self>) -> ExtrinsicInclusionMode {
			let _: HeaderFor<Self> = header.clone();
			RuntimeExecutive::initialize_block(header)
		}
		// ...
         }
// ...
```

<details open>

<summary>Output:</summary>

```bash
$ cargo build --release -p minimal-template-node
  error: `Self` can not be used as type argument in the scope of `impl_runtime_apis!`. Use `Runtime` instead.

A quick fix to the step that generates a temporary token used in the
pipeline

# Description

Prior to this PR, the metadata for runtime APIs was entirely based on
that generated by `decl_runtime_apis`. It therefore didn't take into
account that `impl_runtime_apis` might implement older versions of APIs
than what has been declared.

This PR filters the returned runtime API metadata to only include
methods actually implemented, and also avoids including methods labelled
with `changed_in` (which the previous code was atempting to do already
but not successfully, owing to the attr being removed prior to the
check).

We also change all version related things to be `u32`s (rather than
VERSION being `u32` and `api_version`s being `u64`) for consistency /
ease of comparison.

A test is added which works with both the `enable-staging-api` feature
in api/tests enabled or disabled, to check all of this.

The tests used the same paths. When run on CI, each test is run in its
own process and thus, this "serial_test" crate wasn't used. The tests
are now using their own thread local tempdir, which ensures that the
tests are working when running in parallel in the same program or when
being run individually.

Previously, when receiving the `SetReservedPeers { reserved }` all peers
not in the `reserved` set were removed.

This is incorrect, the intention of `SetReservedPeers` is to change the
active set of reserved peers and disconnect previously reserved peers
not in the new set.

While at it, have added a few other improvements to make the peerset
more robust:
- `SetReservedPeers`: does not disconnect all peers
- `SetReservedPeers`: if a reserved peer is no longer reserved, the
peerset tries to move the peers to the regular set if the slots allow
this move. This ensures the (now regular) peer counts towards slot
allocation.
- every 1 seconds: If we don't have enough connect peers, add the
reserved peers to the list that the peerstore ignores. Reserved peers
are already connected and the peerstore might return otherwise a
reserved peer

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"),
```
```diff
		fn dispatch_benchmark(
			config: frame_benchmarking::BenchmarkConfig
-		) -> Res...

I've broken this test with
https://github.com/paritytech/polkadot-sdk/pull/5883 and this is the
fix.

The benchmark is now updated to use proper core index and session index
for the generated candidates.

For marking `Check SemVer` required

Resolves https://github.com/paritytech/polkadot-sdk/issues/5930

`spend_local` from `treasury` pallet and associated types are
deprecated. `spend_local` was being used before with native currency in
the treasury.

This PR provides a documentation on how to migrate to the `spend` call
instead.

### Migration

#### For users who were using only `spend_local` before

To replace `spend_local` functionality configure `Paymaster` pallet
configuration to be `PayFromAccount` and configure `AssetKind` to be
`()` and use `spend` call instead.
This way `spend` call will function as deprecated `spend_local`.

Example:
```
impl pallet_treasury::Config for Runtime {
    ..
    type AssetKind = ();
    type Paymaster = PayFromAccount<Self::Currency, TreasuryAccount>;
    // convert balance 1:1 ratio with native currency
    type BalanceConverter = UnityAssetBalanceConversion;
    ..
}
```

#### For users who were already using `spend` with all other assets,
except the native asset

Use `NativeOrWithId` type for `AssetKind` and have a `UnionOf` for
native and non-native assets, then use that with `PayAssetFromAccount`.

Example from `kitchensink-runtime`:
```
// Union of native currency and assets
pub type NativeAndAssets =
    UnionOf<Balances, Assets, NativeFromLeft, NativeOrWithId<u32>, AccountId>;

impl pallet_treasury::Config for Runtime {
    ..
    type AssetKind = NativeOrWithId<u32>;
    type Paymaster = PayAssetFromAccount<NativeAndAssets, TreasuryAccount>;
    type BalanceConverter = AssetRate;
    ..
}

// AssetRate pallet configuration
impl pallet_asset_rate::Config for Runtime {
    ..
    type Currency = Balances;
    type AssetKind = NativeOrWithId<u32>;
    ..
}
```

closes https://github.com/paritytech/polkadot-sdk/issues/5791.

This is not strictly necessary but serves as a defensive check.

The staking pallet exposes
[apis](https://paritytech.github.io/polkadot-sdk/master/sp_staking/trait.StakingUnchecked.html#tymethod.virtual_bond)
that other runtime pallets (pallet-delegated-staking) can use to create
virtual stakers. However, there’s no way for pallet-staking to ensure
that the staker is truly keyless. If the caller (this is a trusted
caller so this would only happen due to a bug) registers an account with
a private key as a virtual_staker, these accounts could later interact
directly with pallet-staking dispatchables (such as
[bond_extra](https://paritytech.github.io/polkadot-sdk/master/pallet_staking/dispatchables/fn.bond_extra.html))
and bypass any locking mechanism. The check above ensures this scenario
can never occur by performing an integrity check.

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's main goal is to add public listen addresses to the DHT
authorities records. This change improves the discoverability of
validators that did not provide the `--public-addresses` flag.

This PR populates the authority DHT records with public listen addresses
if any.

The change effectively ensures that addresses are added to the DHT
record in following order:
 1. Public addresses provided by CLI `--public-addresses`
 2. Maximum of 4 public (global) listen addresses (if any)
3. Any external addresses discovered from the network (ie from
`/identify` protocol)


While at it, this PR adds the following constraints on the number of
addresses:
- Total number of addresses cached is bounded at 16 (increased from 10).
- A maximum number of 32 addresses are published to DHT records
(previously unbounded).
  - A maximum of 4 global listen addresses are utilized.
      
This PR also removes the following warning:
`WARNING: No public address specified, validator node may not be
reachable.`

### Next Steps
- [ ] deploy and monitor in versi network

Resolves issue https://github.com/paritytech/polkadot-sdk/issues/5928

Adds `approve_bounty_with_curator` call to the `bounties` pallet to
combine functions of `approve_bounty` and `propose_curator` into one
call. Also adds a new status `ApprovedWithCurator` required to
distinguish if bounty was approved with curator when skipping through
`Funded` status and moving to `CuratorProposed` status.

If `unassign_curator` is called after `approve_bounty_with_curator` the
process will fall back to the old flow of calling `propose_curator`
separately.

The logline in question doesn't indeed present any interest for a node
operator (I mean, there is not much he can do about that warning), but
in a heavy transaction load situation, when each of 5000 transactions in
txpool produces a warning, it's really annoying. Still, it's useful for
a developer, so I propose to log it at the `debug` level.
