`LiveAsset` is an error to be returned when an asset is not supposed to
be live.
And `AssetNotLive` is an error to be returned when an asset is supposed
to be live, I don't think frozen qualifies as live.

The first test proves that parachains who were migrated over on a legacy
lease can renew without downtime.

The exception is if their lease expires in period 0 - aka within
`region_length` timeslices after `start_sales` is called. The second
test is designed such that it passes if the issue exists and should be
fixed.
This will require an intervention on Kusama to add these renewals to
storage as it is too tight to schedule a runtime upgrade before the
start_sales call. All leases will still have at least two full regions
of coretime.

Changes:
- Add pallet-parameters to Rococo to configure the NIS and preimage
pallet.
- Fix names of expanded dynamic params. Apparently, `to_class_case`
removes suffix `s`, and `Nis` becomes `Ni` 😑

`to_pascal_case`.

This PR introduces `BlockHashProvider` into `pallet_mmr::Config`
This type is used to get `block_hash` for a given `block_number` rather
than directly using `frame_system::Pallet::block_hash`

The `DefaultBlockHashProvider` uses `frame_system::Pallet::block_hash`
to get the `block_hash`

Closes: #4062

Small adjustments which should make understanding what is going on much
easier for future readers.

Initialization is a bit messy, the very least we should do is adding
documentation to make it harder to use wrongly.

I was thinking about calling `request_core_count` right from
`start_sales`, but as explained in the docs, this is not necessarily
what you want.

Current benchmarking macro returns a closure with the captured
benchmarked code.
This can cause issues when the benchmarked code has complex lifetime
requirements.

This PR updates the existing macro by injecting the recording parameter
and invoking the start / stop method around the benchmarked block
instead of returning a closure

One other added benefit is that you can write this kind of code now as
well:

```rust
let v;
#[block]
{ v = func.call(); }
dbg!(v); // or assert something on v
```

Fix some broken legacy definitions of pallet_contracts_uapi storage host
functions

Cumulus test-parachain node and test runtime were still using relay
chain consensus and 12s blocktimes. With async backing around the corner
on the major chains we should switch our tests too.

Also needed to nicely test the changes coming to collators in #3168.

### Changes Overview
- Followed the [migration
guide](https://wiki.polkadot.network/docs/maintain-guides-async-backing)
for async backing for the cumulus-test-runtime
- Adjusted the cumulus-test-service to use the correct import-queue,
lookahead collator etc.
- The block validation function now uses the Aura Ext Executor so that
the seal of the block is validated
- Previous point requires that we seal block before calling into
`validate_block`, I introduced a helper function for that
- Test client adjusted to provide a slot to the relay chain proof and
the aura pre-digest

Update the Contracts API to use `WeightMeter`, as it simplifies the code
and makes it easier to reason about, rather than taking a mutable weight
or returning a tuple with the weight consumed

This MR contains two major changes and some maintenance cleanup.  

## 1. Free Standing Pallet Benchmark Runner

Closes https://github.com/paritytech/polkadot-sdk/issues/3045, depends
on your runtime exposing the `GenesisBuilderApi` (like
https://github.com/paritytech/polkadot-sdk/pull/1492).

Introduces a new binary crate: `frame-omni-bencher`.  
It allows to directly benchmark a WASM blob - without needing a node or
chain spec.

This makes it much easier to generate pallet weights and should allow us
to remove bloaty code from the node.
It should work for all FRAME runtimes that dont use 3rd party host calls
or non `BlakeTwo256` block hashing (basically all polkadot parachains
should work).

It is 100% backwards compatible with the old CLI args, when the `v1`
compatibility command is used. This is done to allow for forwards
compatible addition of new commands.

### Example (full example in the Rust docs)

```sh

This PR adds a check that `max_timeslices > 0` and errors if not. It
also adds a test for this behaviour and cleans up some misleading docs.

The runtime now can provide a number of predefined presets of
`RuntimeGenesisConfig` struct. This presets are intended to be used in
different deployments, e.g.: `local`, `staging`, etc, and should be
included into the corresponding chain-specs.

Having `GenesisConfig` presets in runtime allows to fully decouple node
from runtime types (the problem is described in #1984).

**Summary of changes:**
- The `GenesisBuilder` API was adjusted to enable this functionality
(and provide better naming - #150):
   ```rust
    fn preset_names() -> Vec<PresetId>;
fn get_preset(id: Option<PresetId>) -> Option<serde_json::Value>;
//`None` means default
    fn build_state(value: serde_json::Value);
    pub struct PresetId(Vec<u8>);
   ```

- **Breaking change**: Old `create_default_config` method was removed,
`build_config` was renamed to `build_state`. As a consequence a node
won't be able to interact with genesis config for older runtimes. The
cleanup was made for sake of API simplicity. Also IMO maintaining
compatibility with old API is not so crucial.
- Reference implementation was provided for `substrate-test-runtime` and
`rococo` runtimes. For rococo new
[`genesis_configs_presets`](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/polkadot/runtime/rococo/src/genesis_config_presets.rs#L530)
module was added and is used in `GenesisBuilder`
[_presets-related_](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/polkadot/runtime/rococo/src/lib.rs#L2462-L2485)
methods.

- The `chain-spec-builder` util was also improved and allows to
([_doc_](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/substrate/bin/utils/chain-spec-builder/src/lib.rs#L19)):
   - list presets provided by given runtime (`list-presets`),
- display preset or default config provided by the runtime
(`display-preset`),
   - build chain-spec using named preset (`create ... named-preset`),


- The `ChainSpecBuilder` is extended with
[`with_genesis_config_preset_name`](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/substrate/client/chain-spec/src/chain_spec.rs#L447)
method which allows to build chain-spec using named preset provided by
the runtime. Sample usage on the node side
[here](https://github.com/paritytech/polkadot-sdk/blob/2caffaae

/polkadot/node/service/src/chain_spec.rs#L404).

Implementation of #1984.

## Basic example showcasing a migration using the MBM framework

This PR has been built on top of
https://github.com/paritytech/polkadot-sdk/pull/1781 and adds two new
example crates to the `examples` pallet

### Changes Made:

Closes https://github.com/paritytech/polkadot-sdk/issues/2977

The issue appears to stem from the `aquamarine` crate failing to render
diagrams in re-exported crates.

e.g. as raised
[here](https://github.com/paritytech/polkadot-sdk/issues/2977), diagrams
would render at `frame_support::traits::Hooks` but not the re-exported
doc `frame::traits::Hooks`, even if I added `aquamarine` as a `frame`
crate dependency.

To resolve this, I followed advice in
https://github.com/mersinvald/aquamarine/issues/20 to instead render
mermaid diagrams directly using JS by adding an `after-content.js`.

migrations: prevent accidentally using unversioned migrations instead of `VersionedMigration` (#3835)

closes #1324 

#### Problem
Currently, it is possible to accidentally use inner unversioned
migration instead of `VersionedMigration` since both implement
`OnRuntimeUpgrade`.

#### Solution

With this change, we make it clear that value of `Inner` is not intended
to be used directly. It is achieved by bounding `Inner` to new trait
`UncheckedOnRuntimeUpgrade`, which has the same interface (except
`unchecked_` prefix) as `OnRuntimeUpgrade`.

#### `try-runtime` functions

Since developers can implement `try-runtime` for `Inner` value in
`VersionedMigration` and have custom logic for it, I added the same
`try-runtime` functions to `UncheckedOnRuntimeUpgrade`. I looked for a
ways to not duplicate functions, but couldn't find anything that doesn't
significantly change the codebase. So I would appreciate If you have any
suggestions to improve this

Working towards migrating the `parity-bridges-common` repo inside
`polkadot-sdk`. This PR upgrades some dependencies in order to align
them with the versions used in `parity-bridges-common`

Related to
https://github.com/paritytech/parity-bridges-common/issues/2538

derive-syn-parse v0.2.0 came out recently which (finally) adds support
for syn 2x.

Upgrading to this will remove many of the places where syn 1x was still
compiling alongside syn 2x in the polkadot-sdk workspace.

This also upgrades `docify` to 0.2.8 which is the version that upgrades
derive-syn-pasre to 0.2.0.

Additionally, this consolidates the `docify` versions in the repo to all
use the latest, and in one case upgrades to the 0.2x syntax where 0.1.x
was still being used.

Related Issue https://github.com/paritytech/polkadot-sdk/issues/3398

This PR makes permissionless withdrawing the default option, giving any
network participant access to claim pool rewards on member's behalf. Of
course, members can still opt out of this by setting a `Permissioned`
claim permission.

Permissionless claiming has been a part of the nomination pool pallet
for around 9 months now, with very limited uptake (~4% of total pool
members). 1.6% of pool members are using `PermissionlessAll`, strongly
suggesting it is not wanted - it is too ambiguous and doesn't provide
guidance to claimers.

Stakers expect rewards to be claimed on their behalf by default - I have
expanded upon this in detail within the [accompanying issue's
discussion](https://github.com/paritytech/polkadot-sdk/issues/3398).
Other protocols have this behaviour, whereby staking rewards are
received without the staker having to take any action. From this
perspective, permissionless claiming is not intuitive for pool members.
As evidence of this, over 150,000 DOT is currently unclaimed on
Polkadot, and is growing at a non-linear rate.
