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.

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.

Fixes https://github.com/paritytech/polkadot-sdk/issues/232

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`

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.

# Description

*Removes the deprecated `trait Store` feature from the code base*

Fixes #222

---------

Co-authored-by: Dónal Murray <[email protected]>

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.

Related: #3326 
CC @muraca

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.

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).

These 2 functions should have been tagged as stable

Unfortunately, the flakiness wasn't fixed by
https://github.com/paritytech/polkadot-sdk/pull/3595. Let's disable the
test in the meanwhile since it is hanging on the CI a lot.

Currently, pool member funds cannot be unbonded if the depositor's stake
is less than `MinNominatorBond`. This usually happens after
`T::MinNominatorBond` is increased.

To fix this, the above mentioned condition is added as a case for
permissionless dispatch of `chill`. After pool is chilled, pool members
can unbond their funds since pool won't be nominating anymore.

Consequently, same check is added to `nominate` call, i.e pool can not
start nominating if it's depositor does not have `MinNominatorBond`

In order to prepare for PolkaVM support I removed the wat support from
our test fixture crate.

- Removed redundant tests (invalid module checks are already inside the
prepare module where they belong
- Converted the gas_sync tests to Rust
- Moved the start function test to the `wasm` module

This PR extends the Initialized event of the chainHead_follow
subscription.

Now, the event provides multiple finalized block hashes. This
information allows clients that are disconnected, and that want to
reconnect, to not lose information about the state of the chain.

At the moment, the spec encourages servers to provide at least 1 minute
of finalized blocks (~10 blocks). The users are responsible for
unpinning these blocks at a later time. This PR tries to report at least
1 finalized block and at most 16 blocks, if they are available.

Changes:
- `QueueFootprint` gets a new field; `ready_pages` that contains the
non-overweight and not yet processed pages.
- `XCMP` queue pallet is change to use the `ready_pages` instead of
`pages` to calculate the channel suspension thresholds.

This should give the XCMP queue pallet a more correct view of when to
suspend channels.

The first step towards
https://github.com/paritytech/polkadot-sdk/issues/3155

Brings all templates under the following structure

```
templates
|   parachain
|   |   polkadot-launch
|   |   runtime              --> parachain-template-runtime
|   |   pallets              --> pallet-parachain-template
|   |   node                 --> parachain-template-node
|   minimal
|   |   runtime              --> minimal-template-runtime
|   |   pallets              --> pallet-minimal-template
|   |   node                 --> minimal-template-node
|   solochain
|   |   runtime              --> solochain-template-runtime
|   |   pallets              --> pallet-template (the naming is not consistent here)
|   |   node                 --> solochain-template-node
```

The only note-worthy changes in this PR are: 

- More `Cargo.toml` fields are forwarded to use the one from the
workspace.
- parachain template now has weights and benchmarks
- adds a shell pallet to the minimal template
- remove a few unused deps 


A list of possible follow-ups: 

- [ ] Unify READMEs, create a parent README for all
- [ ] remove references to `docs.substrate.io` in templates
- [ ] make all templates use `#[derive_impl]`
- [ ] update and unify all licenses
- [ ] Remove polkadot launch, use
https://github.com/paritytech/polkadot-sdk/blob/35349df9/cumulus/zombienet/examples/small_network.toml
instead.

Part of #3326 
This one is easier as all the storage items are public.

Fixes failures like:
https://gitlab.parity.io/parity/mirrors/polkadot-sdk/-/jobs/5436619#L3319

After some discussion with @kogeler

 after the we added the rate-limit
middleware it may slow down
the rpc call timings metrics significantly because it works as follows:

1. The rate limit guard is checked when the call comes and if a slot is
available -> process the call
2. If no free spot is available then the call will be sleeping
`jitter_delay + min_time_rate_guard` then woken up and checked at most
ten times
3. If no spot is available after 10 iterations -> the call is rejected
(this may take tens of seconds)

Thus, this PR adds a label "is_rate_limited" to filter those out on the
metrics "substrate_rpc_calls_time" and "substrate_rpc_calls_finished".

I had to merge two middleware layers Metrics and RateLimit to avoid
shared state in a hacky way.
