Fixes #3128.

This introduces a new variant for the collation response from the
collator that includes the parent head data. For now, collators won't
send this new variant. We'll need to change the collator side of the
collator protocol to detect all the cores assigned to a para and send
the parent head data in the case when it's more than 1 core.

- [x] validate approach
- [x] check head data hash

Step in https://github.com/paritytech/polkadot-sdk/issues/171

This PR removes `as [disambiguation_path]` syntax from `derive_impl`
usage across the polkadot-sdk as introduced in
https://github.com/paritytech/polkadot-sdk/pull/3505

This change includes new bootnodes for Paseo. 

_This is meant to be a silent PR_

Issues addressed in this PR:
- Improve *Penpal* runtime:
- Properly handled received assets. Previously, it treated `(1, Here)`
as the local native currency, whereas it should be treated as a
`ForeignAsset`. This wasn't a great example of standard Parachain
behaviour, as no Parachain treats the system asset as the local
currency.
- Remove `AllowExplicitUnpaidExecutionFrom` the system. Again, this
wasn't a great example of standard Parachain behaviour.
- Move duplicated
`ForeignAssetFeeAsExistentialDepositMultiplierFeeCharger` to
`assets_common` crate.
- Improve emulated tests:
  - Update *Penpal* tests to new runtime.
- To simplify tests, register the reserve transferred, teleported, and
system assets in *Penpal* and *AssetHub* genesis. This saves us from
having to create the assets repeatedly for each test
- Add missing test case:
`reserve_transfer_assets_from_para_to_system_para`.
  - Cleanup.
- Prevent integration tests crates imports from being re-exported, as
they were polluting the `polkadot-sdk` docs.

There is still a test case missing for reserve transfers:
- Reserve transfer of system asset from *Parachain* to *Parachain*
trough *AssetHub*.
- This is not yet possible with `pallet-xcm` due to the reasons
explained in https://github.com/paritytech/polkadot-sdk/pull/3339

Currently, the staking logic does not prevent a controller from becoming
a stash of *another* ledger (introduced by [removing this
check](https://github.com/paritytech/polkadot-sdk/pull/1484/files#diff-3aa6ceab5aa4e0ab2ed73a7245e0f5b42e0832d8ca5b1ed85d7b2a52fb196524L850)).
Given that the remaining of the code expects that never happens, bonding
a ledger with a stash that is a controller of another ledger may lead to
data inconsistencies and data losses in bonded ledgers. For more
detailed explanation of this issue:
https://hackmd.io/@gpestana/HJoBm2tqo/%2FTPdi28H7Qc2mNUqLSMn15w

In a nutshell, when fetching a ledger with a given controller, we may be
end up getting the wrong ledger which can lead to unexpected ledger
states.

This PR also ensures that `set_controller` does not lead to data
inconsistencies in the staking ledger and bonded storage in the case
when a controller of a stash is a stash of *another* ledger. and
improves the staking `try-runtime` checks to catch potential issues with
the storage preemptively.

In summary, there are two important cases here:

1. **"Sane" double bonded ledger**

When a controller of a ledger is a stash of *another* ledger. In this
case, we have:

```
> Bonded(stash, controller)
(A, B)  // stash A with controller B
(B, C) // B is also a stash of another ledger
(C, D)

> Ledger(controller)
Ledger(B) = L_a (stash = A)
Ledger(C) = L_b (stash = B)
Ledger(D) = L_c (stash = C)
```

In this case, the ledgers can be mutated and all operations are OK.
However, we should not allow `set_controller` to be called if it means
it results in a "corrupt" double bonded ledger (see below).

3. **"Corrupt" double bonded ledger**

```
> Bonded(stash, controller)
(A, B)  // stash A with controller B
(B, B)
(C, D)
```
In this case, B is a stash and controller AND is corrupted, since B is
responsible for 2 ledgers which is not correct and will lead to
inconsistent states. Thus, in this case, in this PR we are preventing
these ledgers from mutating (i.e. operations like bonding extra etc)
until the ledger is brought back to a consistent state.

--- 

**Changes**:
- Checks if stash is already a controller when calling `Call::bond`
(fixes the regression introduced by [removing this
check](https://github.com/paritytech/polkadot-sdk/pull/1484/files#diff-3aa6ceab5aa4e0ab2ed73a7245e0f5b42e0832d8ca5b1ed85d7b2a52fb196524L850));
- Ensures that all fetching ledgers from storage are done through the
`StakingLedger` API;
- Ensures that -- when fetching a ledger from storage using the
`StakingLedger` API --, a `Error::BadState` is returned if the ledger
bonding is in a bad state. This prevents bad ledgers from mutating (e.g.
`bond_extra`, `set_controller`, etc) its state and avoid further data
inconsistencies.
- Prevents stashes which are controllers or another ledger from calling
`set_controller`, since that may lead to a bad state.
- Adds further try-state runtime checks that check if there are ledgers
in a bad state based on their bonded metadata.

This is printed every 10 minutes, I see no reason why it shouldn't be in
all the logs, it would give us valuable information about what is going
on with node connectivity when validators come-back to us to report
issues.

Revert "FRAME: Create `TransactionExtension` as a replacement for `SignedExtension` (#2280)" (#3665)

This PR reverts #2280 which introduced `TransactionExtension` to replace
`SignedExtension`.

As a result of the discussion
[here](https://github.com/paritytech/polkadot-sdk/pull/3623#issuecomment-1986789700),
the changes will be reverted for now with plans to reintroduce the
concept in the future.

This PR adds a debug log for displaying all the public addresses that
will later be advertised in the DHT record of the authority. The
Authority DHT record will contain the address ++ `/p2p/peerID` (if not
already present).

This log enables us to check if different nodes will advertise in the
DHT record of the authority the same IP address, however with different
peer IDs.

This PR introduces outer-macro approach for `construct_runtime` as
discussed in the linked issue. It looks like the following:
```rust
#[frame_support::runtime]
mod runtime {
	#[runtime::runtime]
        #[runtime::derive(
		RuntimeCall,
		RuntimeEvent,
		RuntimeError,
		RuntimeOrigin,
		RuntimeFreezeReason,
		RuntimeHoldReason,
		RuntimeSlashReason,
		RuntimeLockId,
                RuntimeTask,
	)]
	pub struct Runtime;

	#[runtime::pallet_index(0)]
	pub type System = frame_system;

	#[runtime::pallet_index(1)]
	pub type Timestamp = pallet_timestamp;

	#[runtime::pallet_index(2)]
	pub type Aura = pallet_aura;

	#[runtime::pallet_index(3)]
	pub type Grandpa = pallet_grandpa;

	#[runtime::pallet_index(4)]
	pub type Balances = pallet_balances;

	#[runtime::pallet_index(5)]
	pub type TransactionPayment = pallet_transaction_payment;

	#[runtime::pallet_index(6)]
	pub type Sudo = pallet_sudo;

	// Include the custom logic from the pallet-template in the runtime.
	#[runtime::pallet_index(7)]
	pub type TemplateModule = pallet_template;
}
```

## Features
- `#[runtime::runtime]` attached to a struct defines the main runtime
- `#[runtime::derive]` attached to this struct defines the types
generated by runtime
- `#[runtime::pallet_index]` must be attached to a pallet to define its
index
- `#[runtime::disable_call]` can be optionally attached to a pallet to
disable its calls
- `#[runtime::disable_unsigned]` can be optionally attached to a pallet
to disable unsigned calls
- A pallet instance can be defined as `TemplateModule:
pallet_template<Instance>`
- An optional attribute can be defined as
`#[frame_support::runtime(legacy_ordering)]` to ensure that the order of
hooks is same as the order of pallets (and not based on the
pallet_index). This is to support legacy runtimes and should be avoided
for new ones.

## Todo
- [x] Update the latest syntax in kitchensink and tests
- [x] Update UI tests
- [x] Docs

## Extension
- Abstract away the Executive similar to
https://github.com/paritytech/substrate/pull/14742
- Optionally avoid the need to specify all runtime types (TBD)

This functionality is required for #1984.

This PR enables
[`sp-keyring`](https://github.com/paritytech/polkadot-sdk/blob/21d36b7b/substrate/primitives/keyring/src/sr25519.rs#L31-L40)
in `no-std` environments, allowing to generate the public key (e.g.
`AccountKeyring::Alice.public().to_ss58check()`), which can be later
used in the any of built-in [_runtime-genesis-config_
variant](https://github.com/paritytech/polkadot-sdk/blob/21d36b7b/polkadot/node/service/src/chain_spec.rs#L1066-L1073).


The proposal is as follows:
- expose [`core::Pair`
trait](https://github.com/paritytech/polkadot-sdk/blob/d6f15306

/substrate/primitives/core/src/crypto.rs#L832)
in `no-std`,
- `full_crypto` feature enables `sign` method,
- `std` feature enables `generate_with_phrase` and `generate` methods
(randomness is required),
- All other functionality, currently gated by `full_crypto` will be
available unconditionally (`no-std`):
-- `from_string`
-- `from_string_with_seed`
-- `from seed`
-- `from_seed_slice`
-- `from_phrase`
-- `derive`
-- `verify`

Depends on https://github.com/rust-bitcoin/rust-bip39/pull/57

Sometimes we see nodes printing this warning:
```
cannot query the runtime API version: Api called for an unknown Block: State already discarded for
```

The log is harmless, but let's print the api we got this for, so that we
can track its call site and truly confirm it is harmless or fix it.

This PR adds a new PolkaVM-based executor to Substrate.

- The executor can now be used to actually run a PolkaVM-based runtime,
and successfully produces blocks.
- The executor is always compiled-in, but is disabled by default.
- The `SUBSTRATE_ENABLE_POLKAVM` environment variable must be set to `1`
to enable the executor, in which case the node will accept both WASM and
PolkaVM program blobs (otherwise it'll default to WASM-only). This is
deliberately undocumented and not explicitly exposed anywhere (e.g. in
the command line arguments, or in the API) to disincentivize anyone from
enabling it in production. If/when we'll move this into production usage
I'll remove the environment variable and do it "properly".
- I did not use our legacy runtime allocator for the PolkaVM executor,
so currently every allocation inside of the runtime will leak guest
memory until that particular instance is destroyed. The idea here is
that I will work on the https://github.com/polkadot-fellows/RFCs/pull/4
which will remove the need for the legacy allocator under WASM, and that
will also allow us to use a proper non-leaking allocator under PolkaVM.
- I also did some minor cleanups of the WASM executor and deleted some
dead code.

No prdocs included since this is not intended to be an end-user feature,
but an unofficial experiment, and shouldn't affect any current
production user. Once this is production-ready a full Polkadot
Fellowship RFC will be necessary anyway.

Fixes some typos, outdated comments and test asserts. Also uses safe
math and `defensive` for arithmetic operations.

As I've been dancing around this pallet for quite some time anyway, I
decided to remove getters at once. There were only a few leftovers in
tests.

This fixes the behaviour of `Linear` which is the default implementation
of the `AdaptPrice` trait in the broker pallet. Previously if cores were
offered but not sold in only one sale, the price would be set to zero
and due to the logic being purely multiplicative, the price would stay
at 0 indefinitely.

This could be further paired with a configurable minimum in the broker
pallet itself, which will be a future PR.

This affects the Rococo and Westend Coretime chains, but Kusama has a
different implementation so this isn't required for the Kusama launch. I
actually thought I opened this a while ago.

Currently redesigning candidate data structures, noticed that this one
seems dead.

This PR add extra checks for the input fields in the GHA which does the
docker image build and publishing.

This documentation guide to address an incorrect exchange rate for a
non-withdrawable pool.

## Context

Implementing `HolderOf(collection_id)` we have observed a fancy glitch
where pallet deposits event with incorrect values

### Test case 

[Observe following
extrinsic](https://assethub-polkadot.subscan.io/extrinsic/0xdc72321b7674aa209c2f194ed49bd6bd12708af103f98b5b9196e0132dcba777)

To mint in collection `51` user needs to be `HolderOf(50)`.
Therefore current user is owner of item `394` `witness_data {
owned_item: 394 }`

All checking is done correctly, storage is updated correctly

However the event which is emitted does not make semantic sense as we
updated storage for `50-394` not for `51-114`

## The fix 

This PR fixes that depositing `PalletAttributeSet` emits correct values.

This PR replaces the usage of
[secp256k](https://crates.io/crates/secp256k1) crate with
[k256](https://crates.io/crates/k256) in `core::crypto::ecdsa` for
`non-std` environments as outcome of discussion in #3448.

`secp256k1` is used in `std`, meaning that we should not affect host
performance with this PR.
`k256` is enabled in runtimes (`no-std`), and is required to proceed
with #2044.

If desirable, in future we can switch to `k256` also for `std`. That
would require some performance evaluation (e.g. for EVM chains as per
https://github.com/paritytech/polkadot-sdk/issues/3448#issuecomment-1976780391).

Looking at rococo-asset-hub
https://github.com/paritytech/polkadot-sdk/issues/3519 there seems to be
a lot of instances where collator did not advertise their collations,
while there are multiple problems there, one of it is that we are
connecting and disconnecting to our assigned validators every block,
because on reconnect_timeout every 4s we call connect_to_validators and
that will produce 0 validators when all went well, so set_reseverd_peers
called from validator discovery will disconnect all our peers.
More details here:
https://github.com/paritytech/polkadot-sdk/issues/3519#issuecomment-1972667343

Now, this shouldn't be a problem, but it stacks with an existing bug in
our network stack where if disconnect from a peer the peer might not
notice it, so it won't detect the reconnect either and it won't send us
the necessary view updates, so we won't advertise the collation to it
more details here:

https://github.com/paritytech/polkadot-sdk/issues/3519#issuecomment-1972958276

To avoid hitting this condition that often, let's keep the peers in the
reserved set for the entire duration we are allocated to a backing
group. Backing group sizes(1 rococo, 3 kusama, 5 polkadot) are really
small, so this shouldn't lead to that many connections. Additionally,
the validators would disconnect us any way if we don't advertise
anything for 4 blocks.

## TODO
- [x] More testing.
- [x] Confirm on rococo that this is improving the situation. (It
doesn't but just because other things are going wrong there).

ApiVersion should have been bumped with
https://github.com/paritytech/polkadot-sdk/pull/3606
this does that and add a test so we don't forget to do that everytime

This is a refactoring, no changes to the logic are included (if you find
some, report :D).

## Change Overview
In https://github.com/paritytech/polkadot-sdk/issues/2455, dependency on
actual runtimes was removed for the system parachains. This means that
the trait bounds we have on various `start_node_xy` do not check
anything anymore, since they all point to the same runtime. Exception is
asset-hub-polkadot which uses a different key type.

This PR unifies the different nodes as much as possible.
`start_node_impl` is doing the heavy lifting and has been made a bit
more flexible to support the rpc extension instantiation that was there
before.

The generics for `Runtime` and `AuraId` have been removed where
possible. The fake runtime is imported as `FakeRuntime` to make it very
clear to readers that it is not the generic parameter.

Multiple nodes where using the same import queue/start_consensus
closure, they have been unified.
