Migrate staking currency from `traits::LockableCurrency` to
`traits::fungible::holds`.

Resolves part of https://github.com/paritytech/polkadot-sdk/issues/226.

## Changes
### Nomination Pool
TransferStake is now incompatible with fungible migration as old pools
were not meant to have additional ED. Since they are anyways deprecated,
removed its usage from all test runtimes.

### Staking
- Config: `Currency` becomes of type `Fungible` while `OldCurrency` is
the `LockableCurrency` used before.
- Lazy migration of accounts. Any ledger update will create a new hold
with no extra reads/writes. A permissionless extrinsic
`migrate_currency()` releases the old `lock` along with some
housekeeping.
- Staking now requires ED to be left free. It also adds no consumer to
staking accounts.
- If hold cannot be applied to all stake, the un-holdable part is force
withdrawn from the ledger.

### Delegated Staking
The pallet does not add provider for agents anymore.

## Migration stats
### Polkadot
Total accounts that can be migrated: 59564
Accounts failing to migrate: 0
Accounts with stake force withdrawn greater than ED: 59
Total force withdrawal: 29591.26 DOT

### Kusama
Total accounts that can be migrated: 26311
Accounts failing to migrate: 0
Accounts with stake force withdrawn greater than ED: 48
Total force withdrawal: 1036.05 KSM


[Full logs here](https://hackmd.io/@ak0n/BklDuFra0).

## Note about locks (freeze) vs holds
With locks or freezes, staking could use total balance of an account.
But with holds, the account needs to be left with at least Existential
Deposit in free balance. This would also affect nomination pools which
till now has been able to stake all funds contributed to it. An
alternate version of this PR is
https://github.com/paritytech/polkadot-sdk/pull/5658 where staking
pallet does not add any provider, but means pools and delegated-staking
pallet has to provide for these accounts and makes the end to end logic
(of provider and consumer ref) lot less intuitive and prone to bug.

This PR now introduces requirement for stakers to maintain ED in their
free balance. This helps with removing the bug prone incrementing and
decrementing of consumers and providers.

## TODO
- [x] Test: Vesting + governance locked funds can be staked.
- [ ] can `Call::restore_ledger` be removed? @gpestana 
- [x] Ensure unclaimed withdrawals is not affected by no provider for
pool accounts.
- [x] Investigate kusama accounts with balance between 0 and ED.
- [x] Permissionless call to release lock.
- [x] Migration of consumer (dec) and provider (inc) for direct stakers.
- [x] force unstake if hold cannot be applied to all stake.
- [x] Fix try state checks (it thinks nothing is staked for unmigrated
ledgers).
- [x] Bench `migrate_currency`.
- [x] Virtual Staker migration test.
- [x] Ensure total issuance is upto date when minting rewards.

Closes #3149 

## Description

This PR introduces `pallet-asset-rewards`, which allows accounts to be
rewarded for freezing `fungible` tokens. The motivation for creating
this pallet is to allow incentivising LPs.

See the pallet docs for more info about the pallet.

## Runtime changes

The pallet has been added to
- `asset-hub-rococo`
- `asset-hub-westend`

The `NativeAndAssets` `fungibles` Union did not contain `PoolAssets`, so
it has been renamed `NativeAndNonPoolAssets`

A new `fungibles` Union `NativeAndAllAssets` was created to encompass
all assets and the native token.

## TODO
- [x] Emulation tests
- [x] Fill in Freeze logic (blocked
https://github.com/paritytech/polkadot-sdk/issues/3342) and re-run
benchmarks

This PR provides the partial results of the `GetRecord` kademlia query.

This significantly improves the authority discovery records, from ~37
minutes to ~2/3 minutes.
In contrast, libp2p discovers authority records in around ~10 minutes. 

The authority discovery was slow because litep2p provided the records
only after the Kademlia query was completed. A normal Kademlia query
completes in around 40 seconds to a few minutes.
In this PR, partial records are provided as soon as they are discovered
from the network.

### Testing Done

Started a node in Kusama with `--validator` and litep2p backend.
The node discovered 996/1000 authority records in ~ 1 minute 45 seconds.

closes #3967 

## Changes
We now use relay chain slots to measure velocity on chain. Previously we
were storing the current parachain slot. Then in `on_state_proof` of the
`ConsensusHook` we were checking how many blocks were athored in the
current parachain slot. This works well when the parachain slot time and
relay chain slot time is the same. With elastic scaling, we can have
parachain slot times lower than that of the relay chain. In these cases
we want to measure velocity in relation to the relay chain. This PR
adjusts that.


##  Migration
This PR includes a migration. Storage item `SlotInfo` of pallet
`aura-ext` is renamed to `RelaySlotInfo` to better reflect its new
content. A migration has been added that just kills the old storage
item. `RelaySlotInfo` will be `None` initially but its value will be
adjusted after one new relay chain slot arrives.

Add an option to persist EVM transaction hash to a SQL db.
This should make it possible to run a full archive ETH RPC node
(assuming the substrate node is also a full archive node)

Some queries such as eth_getTransactionByHash,
eth_getBlockTransactionCountByHash, and other need to work with a
transaction hash indexes, which are not stored in Substrate and need to
be stored by the eth-rpc proxy.

The refactoring break down the Client into a `BlockInfoProvider` and
`ReceiptProvider`
- BlockInfoProvider does not need any persistence data, as we can fetch
all block info from the source substrate chain
- ReceiptProvider comes in two flavor, 
  - An in memory cache implementation - This is the one we had so far.
- A DB implementation - This one persist rows with the block_hash, the
transaction_index and the transaction_hash, so that we can later fetch
the block and extrinsic for that receipt and reconstruct the ReceiptInfo
object.

# Description

Migrating salary pallet to use umbrella crate. It is a follow-up from
https://github.com/paritytech/polkadot-sdk/pull/7025
Why did I create this new branch? 
I did this, so that the unnecessary cargo fmt changes from the previous
branch are discarded and hence opened this new PR.



## Review Notes

This PR migrates pallet-salary to use the umbrella crate.

Added change: Explanation requested for why `TestExternalities` was
replaced by `TestState` as testing_prelude already includes it
`pub use sp_io::TestExternalities as TestState;`

Migrate pallet-node-authorization to use umbrella crate. Part of #6504 

## Review Notes

* This PR migrates pallet-node-authorization to use the umbrella crate.
* Some imports like below have not been added to any prelude as they
have very limited usage across the various pallets.
```rust
use sp_core::OpaquePeerId as PeerId;
```
* Added a commonly used runtime trait for testing in the
`testing_prelude` in `substrate/frame/src/lib.rs`:
```rust
pub use sp_runtime::traits::BadOrigin;
```
* `weights.rs` uses the `weights_prelude` like:
```rust
use frame::weights_prelude::*;
```
* `tests.rs` and `mock.rs` use the `testing_prelude`:
```rust
use frame::testing_prelude::*;
```
* `lib.rs` uses the main `prelude` like:
```rust
use frame::prelude::*;
```
* For testing: Checked that local build works and tests run
successfully.

# Description

This PR removes usage of deprecated `sp-std` from Substrate. (following
PR of #5010)

## Integration

This PR doesn't remove re-exported `sp_std` from any crates yet, so
downstream projects using re-exported `sp_std` will not be affected.

## Review Notes

The existing code using `sp-std` is refactored to use `alloc` and `core`
directly. The key-value maps are instantiated from a vector of tuples
directly instead of using `sp_std::map!` macro.

`sp_std::Writer` is a helper type to use `Vec<u8>` with
`core::fmt::Write` trait. This PR copied it into `sp-runtime`, because
all crates using `sp_std::Writer` (including `sp-runtime` itself,
`frame-support`, etc.) depend on `sp-runtime`.

If this PR is merged, I would write following PRs to remove remaining
usage of `sp-std` from `bridges` and `cumulus`.

Implement cumulus StorageWeightReclaim as wrapping transaction extension + frame system ReclaimWeight (#6140)

(rebasing of https://github.com/paritytech/polkadot-sdk/pull/5234)

## Issues:

* Transaction extensions have weights and refund weight. So the
reclaiming of unused weight must happen last in the transaction
extension pipeline. Currently it is inside `CheckWeight`.

size of logic happening prior to itself.

## Done:

which attempts to do some reclaim must use this storage to avoid double
reclaim.
* a new function `reclaim_weight` in frame-system pallet: info and post
info in arguments, read the already reclaimed weight, calculate the new
unused weight from info and post info. do the more accurate reclaim if
higher.

Migrate pallet-mixnet to use umbrella crate whilst adding a few types
and traits in the frame prelude that are used by other pallets as well.

## Review Notes

* This PR migrates `pallet-mixnet` to use the umbrella crate. 
* Note that some imports like `use
sp_application_crypto::RuntimeAppPublic;` and imports from
`sp_mixnet::types::` have not been migrated to the umbrella crate as
they are not used in any / many other places and are relevant only to
the `pallet-mixnet`.
* Transaction related helpers to submit transactions from `frame-system`
have been added to the main `prelude` as they have usage across various
pallets.
```Rust
	pub use frame_system::offchain::*;
```
* Exporting `arithmetic` module in the main `prelude` since this is used
a lot throughout various pallets.
* Nightly formatting has been applied using `cargo fmt`
* Benchmarking dependencies have been removed from`palet-mixnet` as
there is no benchmarking.rs present for `pallet-mixnet`. For the same
reason, `"pallet-mixnet?/runtime-benchmarks"` has been removed from
`umbrella/Cargo.toml`.

# Description

Fixes https://github.com/paritytech/polkadot-sdk/issues/5996

https://github.com/libp2p/rust-libp2p/releases/tag/libp2p-v0.53.0
https://github.com/libp2p/rust-libp2p/blob/master/CHANGELOG.md

## Integration

Nothing special is needed, just note that `yamux_window_size` is no
longer applicable to libp2p (litep2p seems to still have it though).

## Review Notes

There are a few simplifications and improvements done in libp2p 0.53
regarding swarm interface, I'll list a few key/applicable here.

https://github.com/libp2p/rust-libp2p/pull/4788 removed
`write_length_prefixed` function, so I inlined its code instead.

https://github.com/libp2p/rust-libp2p/pull/4120 introduced new
`libp2p::SwarmBuilder` instead of now deprecated
`libp2p::swarm::SwarmBuilder`, the transition is straightforward and
quite ergonomic (can be seen in tests).

https://github.com/libp2p/rust-libp2p/pull/4581 is the most annoying
change I have seen that basically makes many enums `#[non_exhaustive]`.
I mapped some, but those that couldn't be mapped I dealt with by
printing log messages once they are hit (the best solution I could come
up with, at least with stable Rust).

https://github.com/libp2p/rust-libp2p/issues/4306 makes connection close
as soon as there are no handler using it, so I had to replace
`KeepAlive::Until` with an explicit future that flips internal boolean
after timeout, achieving the old behavior, though it should ideally be
removed completely at some point.

`yamux_window_size` is no longer used by libp2p thanks to
https://github.com/libp2p/rust-libp2p/pull/4970 and generally Yamux
should have a higher performance now.

I have resolved and cleaned up all deprecations related to libp2p except
`BandwidthSinks`. Libp2p deprecated it (though it is still present in
0.54.1, which is why I didn't handle it just yet). Ideally Substrate
would finally [switch to the official Prometheus
client](https://github.com/paritytech/substrate/issues/12699), in which
case we'd get metrics for free. Otherwise a bit of code will need to be
copy-pasted to maintain current behavior with `BandwidthSinks` gone,
which I left a TODO about.

The biggest change in 0.54.0 is
https://github.com/libp2p/rust-libp2p/pull/4568 that changed transport
APIs and enabled unconditional potential port reuse, which can lead to
very confusing errors if running two Substrate nodes on the same machine
without changing listening port explicitly.

Overall nothing scary here, but testing is always appreciated.

Bump `polkavm` to 0.18.0, and update `sc-polkavm-executor` to be
compatible with the API changes. In addition, bump also `polkavm-derive`
and `polkavm-linker` in order to make sure that the all parts of the
Polkadot SDK use the exact same ABI for `.polkavm` binaries.

Purely relying on RV32E/RV64E ABI is not possible, as PolkaVM uses a
RISCV-V alike ISA, which is derived from RV32E/RV64E but it is still its
own microarchitecture, i.e. not fully binary compatible.

Additionally, the release includes several improvements to the
`identify` protocol, replacing `FuturesUnordered` with `FuturesStream`
for better performance.

### Fixed

- mdns/fix: Failed to register opened substream
([#301](https://github.com/paritytech/litep2p/pull/301))

### Changed

- identify: Replace FuturesUnordered with FuturesStream
([#302](https://github.com/paritytech/litep2p/pull/302))
- chore: Update hickory-resolver to version 0.24.2
([#304](https://github.com/paritytech/litep2p/pull/304))
- ci: Ensure cargo-machete is working with rust version from CI

# Description

Get runtime's metadata, parse it and verify pallets list for a pallet
named `ParachainSystem` (for now), and block number to be the same for
both node and runtime. Ideally we'll add other pallets checks too, at
least a small set of pallets we think right away as mandatory for
parachain compatibility.
Closes: #5565 

## Integration

Runtime devs must be made aware that to be fully compatible with Omni
Node, certain naming conventions should be respected when defining
pallets (e.g we verify parachain-system pallet existence by searching
for a pallet with `name` `ParachainSystem` in runtime's metadata). Not
finding such a pallet will not influence the functionality yet, but by
doing these checks we could provide useful feedback for runtimes that
are clearly not implementing what's required for full parachain
compatibility with Omni Node.

## Review Notes

- [x] parachain system check
- [x] check frame_system's metadata to ensure the block number in there
is the same as the one in the node side
- [x] add tests for the previous checking logic
- [x] update omni node polkadot-sdk docs to make these conventions
visible.
- [ ] add more pallets checks?

order to unify the dependencies I did the following:

1. Switch to the `alloy-core` umbrella crate so that we have less
individual dependencies to update.
2. Bump the latest version and fixup the resulting compile errors.

`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.

an issue with detecting runtime apis when they were implemented in a
