This PR introduces transactional processing of certain xcm instructions.
For the list of instructions checkout
https://github.com/paritytech/polkadot-sdk/issues/490. The transactional
processing is implemented as an xcm-executor config item. The two
implementations in this PR are `FrameTransactionalProcessor` and `()`.
The `()` implementation does no transactional processing. Each
implementation of the `ProcessTransaction` trait has an
`IS_TRANSACTIONAL` const that tells the XCVM if transactional processing
is actually implemented. If Transactional processing is implemented,
changes to touched registers should also be rolled back to prevent
inconsistencies.

There were several improvements and PRs that didn't apply to all
runtimes, so this PR attempts to align those small differences. In
addition, the PR eliminates unused dependencies across multiple modules.

Relates to PR for `polkadot-fellows`:
https://github.com/polkadot-fellows/runtimes/pull/154

Found the issue while investigating the recent finality stall on Westend
after upgrading to 1.6.0. Approval distribution aggression is supposed
to trade off bandwidth and re-send assignemnts/approvals until enough
approvals are be received by at least 2/3 validators. This is supposed
to be a catch all mechanism when network connectivity goes south or many
validators reboot at the same time.

This fix ensures that we always resend approvals starting with the first
unfinalized block even in the case when it appears approved from the
node's perspective.

This is a rather big change in jsonrpsee, the major things in this bump
are:
- Server backpressure (the subscription impls are modified to deal with
that)
- Allow custom error types / return types (remove jsonrpsee::core::Error
and jsonrpee::core::CallError)
- Bug fixes (graceful shutdown in particular not used by substrate
anyway)
   - Less dependencies for the clients in particular
   - Return type requires Clone in method call responses
   - Moved to tokio channels
   - Async subscription API (not used in this PR)

Major changes in this PR:
- The subscriptions are now bounded and if subscription can't keep up
with the server it is dropped
- CLI: add parameter to configure the jsonrpc server bounded message
buffer (default is 64)
- Add our own subscription helper to deal with the unbounded streams in
substrate

The most important things in this PR to review is the added helpers
functions in `substrate/client/rpc/src/utils.rs` and the rest is pretty
much chore.

Regarding the "bounded buffer limit" it may cause the server to handle
the JSON-RPC calls
slower than before.

The message size limit is bounded by "--rpc-response-size" thus "by
default 10MB * 64 = 640MB"
but the subscription message size is not covered by this limit and could
be capped as well.

Hopefully the last release prior to 1.0, sorry in advance for a big PR

https://github.com/paritytech/polkadot-sdk/issues/627

If an Executor is required in some pallet's config, a mock might be
provided where `Executor = ()`. `()` already implements `ExecuteXcm`,
but not `XcmAssetTransfers`, which is also related. This PR just fixes
that so you can skip having to create a whole xcm configuration, which
is non-trivial right now.

Step towards https://github.com/paritytech/polkadot-sdk/issues/1975

As reported
https://github.com/paritytech/polkadot-sdk/issues/1975#issuecomment-1774534225
I'd like to encapsulate crypto related stuff in a dedicated folder.

Currently all cryptographic primitive wrappers are all sparsed in
`substrate/core` which contains "misc core" stuff.

To simplify the process, as the first step with this PR I propose to
move the cryptographic hashing there.

The `substrate/crypto` folder was already created to contains `ec-utils`
crate.

Notes:
- rename `sp-core-hashing` to `sp-crypto-hashing`
- rename `sp-core-hashing-proc-macro` to `sp-crypto-hashing-proc-macro`
- As the crates name is changed I took the freedom to restart fresh from
version 0.1.0 for both crates

The goal is to move all system chains on Rococo (+ other testnets?) to
use async backing.

This PR aims to channel the backpressure of the PVF host's preparation
and execution queues to the candidate validation subsystem consumers.

Related: #708

@mrcnski

 Done the change on the prepare worker, once the prepare worker
part is good I'll do the same for the execute worker.

This is based on
https://github.com/koute/polkavm/blob/11beebd06276ce9b84f335350138479e714f6caf/crates/polkavm/src/sandbox/linux.rs#L711.

- [x] Add prdoc mentioning the new Secure Validator Mode (optional)
requirement.

This PR makes a small change the the adder parachain's CLI. It allows
the user to specify an output file explicitly when generating the
genesis wasm and head data.

Now we no longer have to rely on redirecting the output to a file at the
shell level. This change is nice because if you have any debugging lines
enabled, shell redirection does not work.

More to the point, this makes the adder parachain's CLI match the
cumulus collator's CLI. And that will allow tools like Zombienet (that
support both cumulus and the adder) to use the positional argument.

- [x] fix broken doc links
- [x] fix codec macro typo
https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/node/core/pvf/common/src/error.rs#L81
(see the comment below)
- [x] refactor `ValidationError`, `PrepareError` and related error types
to use `thiserror` crate

## `codec` issue

`codec` macro was mistakenly applied two times to `Kernel` error (so it
was encoded with 10 instead of 11 and the same as `JobDied`). The PR
changes it to 11 because

- it was an initial goal of the code author
- Kernel is less frequent than JobDied so in case of existing error
encoding it is more probable to have 10 as JobDied than Kernel

See https://github.com/paritytech/parity-scale-codec/issues/555

# Note for reviewer

Most changes are just syntax changes necessary for the new version.
Most important files should be the ones under the `xcm` folder.

# Description 

Added XCMv4.

## Removed `Multi` prefix
The following types have been renamed:
- MultiLocation -> Location
- MultiAsset -> Asset
- MultiAssets -> Assets
- InteriorMultiLocation -> InteriorLocation
- MultiAssetFilter -> AssetFilter
- VersionedMultiAsset -> VersionedAsset
- WildMultiAsset -> WildAsset
- VersionedMultiLocation -> VersionedLocation

In order to fix a name conflict, the `Assets` in `xcm-executor` were
renamed to `HoldingAssets`, as they represent assets in holding.

## Removed `Abstract` asset id

It was not being used anywhere and this simplifies the code.

Now assets are just constructed as follows:

```rust
let asset: Asset = (AssetId(Location::new(1, Here)), 100u128).into();
```

No need for specifying `Concrete` anymore.

## Outcome is now a named fields struct

Instead of

```rust
pub enum Outcome {
  Complete(Weight),
  Incomplete(Weight, Error),
  Error(Error),
}
```

we now have

```rust
pub enum Outcome {
  Complete { used: Weight },
  Incomplete { used: Weight, error: Error },
  Error { error: Error },
}
```

## Added Reanchorable trait

Now both locations and assets implement this trait, making it easier to
reanchor both.

## New syntax for building locations and junctions

Now junctions are built using the following methods:

```rust
let location = Location {
    parents: 1,
    interior: [Parachain(1000), PalletInstance(50), GeneralIndex(1984)].into()
};
```

or

```rust
let location = Location::new(1, [Parachain(1000), PalletInstance(50), GeneralIndex(1984)]);
```

And they are matched like so:

```rust
match location.unpack() {
  (1, [Parachain(id)]) => ...
  (0, Here) => ...,
  (1, [_]) => ...,
}
```

This syntax is mandatory in v4, and has been also implemented for v2 and
v3 for easier migration.

This was needed to make all sizes smaller.

# TODO
- [x] Scaffold v4
- [x] Port github.com/paritytech/polkadot/pull/7236
- [x] Remove `Multi` prefix
- [x] Remove `Abstract` asset id

## Why we need it
To provide another level of understanding to why polkadot's subsystems
may perform slower than expected. Cache misses occur when processing
large amounts of data, such as during availability recovery.

## Why Cachegrind
Cachegrind has many drawbacks: it is slow, it uses its own cache
simulation, which is very basic. But unlike `perf`, which is a great
tool, Cachegrind can run in a virtual machine. This means we can easily
run it in remote installations and even use it in CI/CD to catch
possible regressions.

Why Cachegrind and not Callgrind, another part of Valgrind? It is simply
empirically proven that profiling runs faster with Cachegrind.

## First results
First results have been obtained while testing of the approach. Here is
an example.

```

$ cat cachegrind_report.txt

```

The CLI output shows that 1.4% of the L1 data cache missed, which is not
so bad, given that the last-level cache had that data most of the time
missing only 0.3%. Instruction data of the L1 has 0.00% misses of the
time. Looking at an output file with `cg_annotate` shows that most of
the misses occur during reed-solomon, which is expected.

This version includes
- Performance improvements.
- Minor fixes.

Extract `WarpSync` (and `StateSync` as part of warp sync) from
`ChainSync` as independent syncing strategy called by `SyncingEngine`.
Introduce `SyncingStrategy` enum as a proxy between `SyncingEngine` and
specific syncing strategies.

## Limitations
Gap sync is kept in `ChainSync` for now because it shares the same set
of peers as block syncing implementation in `ChainSync`. Extraction of a
common context responsible for peer management in syncing strategies
able to run in parallel is planned for a follow-up PR.

## Further improvements
A possibility of conversion of `SyncingStartegy` into a trait should be
evaluated. The main stopper for this is that different strategies need
to communicate different actions to `SyncingEngine` and respond to
different events / provide different APIs (e.g., requesting
justifications is only possible via `ChainSync` and not through
`WarpSync`; `SendWarpProofRequest` action is only relevant to
`WarpSync`, etc.)

A recent referendum failed because the parachain's sovereign account had
enough funds for the deposit (the runtime at the time required a
deposit) but not enough left over for the existential deposit, which
must remain free.

The current logic does not require a deposit for channels with system
chains, and the current tests check that none is taken. This new test
simply ensures that even without any balance in a parachain's sovereign
account, opening a channel with a system chain will be successful.

changelog</a>.</em></p>
<blockquote>
<ul>
<li>
<p>2.0.0</p>
<ul>
<li>
<p><strong>MSRV</strong>: Rust 1.64.0 or later is now required.</p>
</li>
<li>
<p>The <code>&quot;std&quot;</code> feature is no longer auto-detected.
It is included in the
default feature set, or else can be enabled like any other Cargo
feature.</p>
</li>
<li>
<p>The <code>&quot;serde-1&quot;</code> feature has been removed,
leaving just the optional
<code>&quot;serde&quot;</code> dependency to be enabled like a feature
itself.</p>
</li>
<li>
<p><code>IndexMap::get_index_mut</code> now returns
<code>Option&lt;(&amp;K, &amp;mut V)&gt;</code>, changing
the key part from <code>&amp;mut K</code> to <code>&amp;K</code>. There
is also a new alternative
<code>MutableKeys::get_index_mut2</code> to access the former
behavior.</p>
</li>
<li>
<p>The new <code>map::Slice&lt;K, V&gt;</code> and
<code>set::Slice&lt;T&gt;</code> offer a linear view of maps
and sets, behaving a lot like normal <code>[(K, V)]</code> and
<code>[T]</code> slices. Notably,
comparison traits like <code>Eq</code> only consider items in order,
rather than hash
lookups, and slices even implement <code>Hash</code>.</p>
</li>
<li>
<p><code>IndexMap</code> and <code>IndexSet</code> now have
<code>sort_by_cached_key</code> and
<code>par_sort_by_cached_key</code> methods which perform stable sorts
in place
using a key extraction function.</p>
</li>
<li>
<p><code>IndexMap</code> and <code>IndexSet</code> now have
<code>reserve_exact</code>, <code>try_reserve</code>, and
<code>try_reserve_exact</code> methods that correspond to the same
methods on <code>Vec</code>.
However, exactness only applies to the direct capacity for items, while
the
raw hash table still follows its own rules for capacity and load
factor.</p>
</li>
<li>
<p>The <code>Equivalent</code> trait is now re-exported from the
<code>equivalent</code> crate,
intended as a common base to allow types to work with multiple map
types.</p>
</li>
<li>
<p>The <code>hashbrown</code> dependency has been updated to version
0.14.</p>
</li>
<li>
<p>The <code>serde_seq</code> module has been moved from the crate root
to below the
<code>map</code> module.</p>
</li>
</ul>

Considering the complexity of
https://github.com/paritytech/polkadot-sdk/pull/2871 and the discussion
therein, as well as the further complexity introduced by the hardening
in https://github.com/paritytech/polkadot-sdk/pull/2742, as well as the
eventual replacement of wasmtime by PolkaVM, it seems best to remove
this persistence as it is creating more problems than it solves.

## Related

Closes https://github.com/paritytech/polkadot-sdk/issues/2863

Previously, it was only possible to retry the same request on a
different protocol name that had the exact same binary payloads.

Introduce a way of trying a different request on a different protocol if
the first one fails with Unsupported protocol.

This helps with adding new req-response versions in polkadot while
preserving compatibility with unupgraded nodes.

The way req-response protocols were bumped previously was that they were
bundled with some other notifications protocol upgrade, like for async
backing (but that is more complicated, especially if the feature does
not require any changes to a notifications protocol). Will be needed for
implementing https://github.com/polkadot-fellows/RFCs/pull/47

TODO:
- [x]  add tests
- [x] add guidance docs in polkadot about req-response protocol
versioning

This removes the need to unnecessarily provide a very specific data
structure `DatabaseSource` and removes huge `sc-client-db` dependency
from storage monitor. It is now possible to use storage monitor with any
path.

P.S. I still strongly dislike that it pulls `clap` dependency for such a
small feature, but many other crates do as well, so nothing special
here.

This PR allows _username authorities_ to issue unique usernames that
correspond with an account. It also provides two-way lookup, that is
from `AccountId` to a single, "primary" `Username` (alongside
`Registration`) and multiple unique `Username`s to an `AccountId`.

Key features:

- Username Authorities added (and removed) via privileged origin.
- Authorities have a `suffix` and an `allocation`. They can grant up to
`allocation` usernames. Their `suffix` will be appended to the usernames
that they issue. A suffix may be up to 7 characters long.
- Users can ask an authority to grant them a username. This will take
the form `myusername.suffix`. The entire name (including suffix) must be
less than or equal to 32 alphanumeric characters.
- Users can approve a username for themselves in one of two ways (that
is, authorities cannot grant them arbitrarily):
- Pre-sign the entire username (including suffix) with a secret key that
corresponds to their `AccountId` (for keyed accounts, obviously); or
- Accept the username after it has been granted by an authority (it will
be queued until accepted) (for non-keyed accounts like pure proxies or
multisigs).
- The system does not require any funds or deposits. Users without an
identity will be given a default one (presumably all fields set to
`None`). If they update this info, they will need to place the normal
storage deposit.
- If a user does not have any username, their first one will be set as
`Primary`, and their `AccountId` will map to that one. If they get
subsequent usernames, they can choose which one to be their primary via
`set_primary_username`.
- There are some state cleanup functions to remove expired usernames
that have not been accepted and dangling usernames whose owners have
called `clear_identity`.

TODO:

- [x] Add migration to runtimes
- [x] Probably do off-chain migration into People Chain genesis
- [x] Address a few TODO questions in code (please review)
