This PR provides the infrastructure for the pov-reclaim mechanism
discussed in #209. The goal is to provide the current proof size to the
runtime so it can be used to reclaim storage weight.

## New Host Function
- A new host function is provided
[here](https://github.com/skunert/polkadot-sdk/blob/5b317fda

/cumulus/primitives/pov-reclaim/src/lib.rs#L23).
It returns the size of the current proof size to the runtime. If
recording is not enabled, it returns 0.

## Implementation Overview
- Implement option to enable proof recording during import in the
client. This is currently enabled for `polkadot-parachain`,
`parachain-template` and the cumulus test node.
- Make the proof recorder ready for no-std. It was previously only
enabled for std environments, but we need to record the proof size in
`validate_block` too.
- Provide a recorder implementation that only the records the size of
incoming nodes and does not store the nodes itself.
- Fix benchmarks that were broken by async backing changes
- Provide new externalities extension that is registered by default if
proof recording is enabled.
- I think we should discuss the naming, pov-reclaim was more intuitive
to me, but we could also go with clawback like in the issue.

## Impact of proof recording during import
With proof recording: 6.3058 Kelem/s
Without proof recording: 6.3427 Kelem/s

The measured impact on the importing performance is quite low on my
machine using the block import benchmark. With proof recording I am
seeing a performance hit of 0.585%.

This PR introduces the new crate `developer_hub` into the polkadot-sdk
repo. The vision for the developer-hub crate is detailed in [this
document](https://docs.google.com/document/d/1XLLkFNE8v8HLvZpI2rzsa8N2IN1FcKntc8q-Sc4xBAk/edit?usp=sharing).

Other than adding the new crate, it also does the following: 

* Remove the `substrate` crate, as there is now a unique umbrella crate
for multiple things in `developer_hub::polkadot_sdk`.
* (backport candidate) A minor change to `frame-support` macros that
allows `T::RuntimeOrigin` to also be acceptable as the origin type.
* (backport candidate) A minor change to `frame-system` that allows us
to deposit events at genesis because now the real genesis config is
generated via wasm, and we can safely assume `cfg!(feature = "std")`
means only testing. related to #62.
* (backport candidate) Introduces a small `read_events_for_pallet` to
`frame_system` for easier event reading in tests.
* From https://github.com/paritytech/polkadot-sdk-docs/issues/31, it
takes action on improving the `pallet::call` docs.
* From https://github.com/paritytech/polkadot-sdk-docs/issues/31, it
takes action on improving the `UncheckedExtrinsic` docs.

## Way Forward

First, a version of this is deployed temporarily
[here](https://blog.kianenigma.nl/polkadot-sdk/developer_hub/index.html).
I will keep it up to date on a daily basis.

### This Pull Request

I see two ways forward: 

1. We acknowledge that everything in `developer-hub` is going to be WIP,
and merge this asap. We should not yet use links to this crate anywhere.
2. We make this be the feature branch, make PRs against this, and either
gradually backport it, or only merge to master once it is done.

I am personally in favor of option 1. If we stick to option 2, we need a
better way to deploy a staging version of this to gh-pages.

### Issue Tracking

The main issues related to the future of `developer_hub` are: 

- https://github.com/paritytech/polkadot-sdk-docs/issues/31
- https://github.com/paritytech/polkadot-sdk-docs/issues/4
- https://github.com/paritytech/polkadot-sdk-docs/issues/26

- https://github.com/paritytech/polkadot-sdk-docs/issues/36


### After This Pull Request

- [ ] create a redirect for
https://paritytech.github.io/polkadot-sdk/master/substrate/
- [x] analytics 
- [ ] link checker
- [ ] the matter of publishing, and how all of these relative links for
when we do, that is still an open question. There is section on this in
the landing page.
- [ ] updated https://paritytech.github.io/

Add metrics for notification handles so substream events are correctly
reported to Prometheus

Upgraded to version 2.3.0 which includes:
- paritytech/review-bot#103
- paritytech/review-bot#102

see #2189

This PR does the following:
- Bring the user api functions into a new pallet-contracts-uapi (They
are currently defined in ink!
[here])(https://github.com/paritytech/ink/blob/master/crates/env/src/engine/on_chain/ext.rs)
- Add older api versions and unstable to the user api trait.
- Remove pallet-contracts-primitives and bring the types it defined in
uapi / pallet-contracts
- Add the infrastructure to build fixtures from Rust files and test it
works by replacing `dummy.wat` and `call.wat`
- Move all the doc from wasm/runtime.rs to pallet-contracts-uapi.

This will be done in a follow up:
- convert the rest of the test from .wat to rust
- bring risc-v uapi up to date with wasm
- finalize the uapi host fns, making sure everything is codegen from the
source host fns in pallet-contracts

Use `LOG_TARGET/LOG_TARGET_PIN` in logs.

This PR backports the error codes from the spec.

This relies on two specs for defining the error codes:
- Our rpc-spec-v2 https://github.com/paritytech/json-rpc-interface-spec.
- JSON-RPC spec https://www.jsonrpc.org/specification#error_object.

To better describe the error codes, they are divided into two separate
modules `rpc_spec_v2` and `json_rpc_spec` respectively.

The `InvalidSubscriptionID` and `FetchBlockHeader` are merged into the
JSON-RPC spec `INTERNAL_ERROR`.
While the other error codes are adjusted from spec.

Errors that are currently in use:
- -32801 block hash not reported by chainHead_follow or block hash has
been unpinned
- -32802 chainHead_follow started with withRuntime == false
- -32803 chainHead_follow did not generate an
operationWaitingForContinue event

The following are errors defined in the [JSON-RPC
spec](https://www.jsonrpc.org/specification#error_object):
- -32602 The provided parameter isn't one of the expected values, has
different format or is missing
- -32603 Internal server error

Good day,

This PR requests the inclusion of two bootnode entries for Polkadot,
Kusama and Westend as part of LuckyFriday's IBP application. The nodes
are hosted on self-owned hardware in a co-located facility. We've
undertaken connectivity tests ourselves and also from members of the
IBP.

The test commands used are as follows:

```
polkadot --chain westend --base-path /tmp/node --name "Boot" --reserved-only --reserved-nodes "/dns/ibp-boot-westend.luckyfriday.io/tcp/30334/wss/p2p/12D3KooWDg1YEytdwFFNWroFj6gio4YFsMB3miSbHKgdpJteUMB9" --no-hardware-benchmarks

Since `sp-state-machine` and `GenesisConfigBuilderRuntimeCaller` always
set `use_native` to be false.
We should remove this param and make `NativeElseWasmExecutor` behave
like its name.
It could make the above components use the correct execution strategy.

Maybe polkadot do not need about `NativeElseWasmExecutor` anymore. But
it is still needed by other chains and it's useful for debugging.

Since the Polkadot and Kusama runtimes are no longer in the repo, the
relevant systems parachains runtimes also need to be removed. More
context [here](https://github.com/paritytech/polkadot-sdk/issues/603)
and [here](https://github.com/paritytech/polkadot-sdk/pull/1731).

Removes the following:
- `asset-hub-kusama` and `asset-hub-polkadot`
- `bridge-hub-kusama` and `bridge-hub-polkadot`
- `collectives-polkadot`
- `glutton-kusama`

Partially solves #603 and adds to #1731.

This PR removes `NativeElseWasmExecutor` usage from substrate node.
Instead [`WasmExecutor<(sp_io::SubstrateHostFunctions,
sp_statement_store::runtime_api::HostFunctions)>`](https://github.com/paritytech/polkadot-sdk/blob/49a41ab3

/substrate/bin/node/executor/src/lib.rs#L26)

Remove deprecated `AllPalletsXY` types.

They have been deprecated for nearly 1.5 years now, I think its fine to
remove them.
If anyone feels like we should first put a date on the deprecation as
stated in the deprecation guideline, feel free to speak up. To me it
looks like this has been forgotten and can be directly removed.

This commit introduces a new concept called `NotificationService` which
allows Polkadot protocols to communicate with the underlying
notification protocol implementation directly, without routing events
through `NetworkWorker`. This implies that each protocol has its own
service which it uses to communicate with remote peers and that each
`NotificationService` is unique with respect to the underlying
notification protocol, meaning `NotificationService` for the transaction
protocol can only be used to send and receive transaction-related
notifications.

The `NotificationService` concept introduces two additional benefits:
  * allow protocols to start using custom handshakes
  * allow protocols to accept/reject inbound peers

Previously the validation of inbound connections was solely the
responsibility of `ProtocolController`. This caused issues with light
peers and `SyncingEngine` as `ProtocolController` would accept more
peers than `SyncingEngine` could accept which caused peers to have
differing views of their own states. `SyncingEngine` would reject excess
peers but these rejections were not properly communicated to those peers
causing them to assume that they were accepted.

With `NotificationService`, the local handshake is not sent to remote
peer if peer is rejected which allows it to detect that it was rejected.

This commit also deprecates the use of `NetworkEventStream` for all
notification-related events and going forward only DHT events are
provided through `NetworkEventStream`. If protocols wish to follow each
other's events, they must introduce additional abtractions, as is done
for GRANDPA and transactions protocols by following the syncing protocol
through `SyncEventStream`.

The test was a bit flaky on CI. 

There was a race condition in the pov-recovery system. If the timing is
bad, it can happen that a block waits for a parent that is already
queued for import. The check if a block has children waiting happens
when we insert into the import queue. So we need to do an additional
check once we receive the import notification for the parent block.

Second issue is that `alice` was missing `--in-peers 0` and `--out-peers
0`, so alice was sometimes still fetching block via sync and the
assertion on the logs in zombienet would fail.

There is another potential issue that I saw once locally. We have a
failing pov-recovery queue that fails from time to time to check that
the retry mechanism does what it should. We now make sure that the same
candidate is never failed twice, so the tests become more predictable.

This was never used and we probably don't need it anyway.

Sets `frame_system::LastRuntimeUpgrade` after running try-runtime
migrations to better emulate real behavior.

This fixes an issue where migrations using the spec version to determine
whether to execute can incorrectly fail idempotency checks.

@s0me0ne-unkn0wn noticed this issue with the session key migration
introduced in https://github.com/paritytech/polkadot-sdk/pull/2265.

Currently the polkadot node will backoff from block authoring if
finality starts lagging. This PR disables this mechanism on production
networks (polkadot and kusama) and adds a flags to optionally force
enabling it.

We're going to bridge Polkadot Bridge Hub with [Polkadot Bulletin
chain](https://github.com/zdave-parity/polkadot-bulletin-chain) soon
(and Rococo Bridge Hub with 1:1 copy of Polkadot Bulletin chain even
sooner), so we need a variant for that chain in `NetworkId`. As
suggested, I'm adding a new variant for it to the `NetworkId` (we may
have used `ByGenesis(_)`, but decision was made to have a dedicated
variant for that).

Addresses #409.

This request has been raised by multiple community members - the ability
for the nomination pool root role to configure permissionless commission
claiming:

> Would it be possible to have a claim_commission_other extrinsic for
claiming commission of nomination pools permissionless?

This PR does not quite introduce this additional call, but amends
`do_claim_commission` to check a new `claim_permission` field in the
`Commission` struct, configured by an enum:

```
enum CommissionClaimPermission {
   Permissionless,
   Account(AccountId),
}
```
This can be optionally set in a bonded pool's
`commission.claim_permission` field:

```
struct BondedPool {
   commission: {
      <snip>
      claim_permission: Option<CommissionClaimPermission<T::AccountId>>,
   },
   <snip>
}
```

This is a new field and requires a migration to add it to existing
pools. This will be `None` on pool creation, falling back to the `root`
role having sole access to claim commission if it is not set; this is
the behaviour as it is today. Once set, the field _can_ be set to `None`
again.

#### Changes
- [x] Add `commision.claim_permission` field.
- [x] Add `can_claim_commission` and amend `do_claim_commission`.
- [x] Add `set_commission_claim_permission` call.
- [x] Test to cover new configs and call.
- [x] Add and amend benchmarks.
- [x] Generate new weights + slot into call
`set_commission_claim_permission`.
- [x] Add migration to introduce `commission.claim_permission`, bump
storage version.
- [x] Update Westend weights.
- [x] Migration working.

README instructions fixes to be compatible with the `polkadot-prepare`
and `polkadot-execute` binary split.

Incorporate suggestion from release team to get this workflow working.

edit: worked on this test GH release:
https://github.com/paritytech/polkadot-sdk/releases/tag/liam-debug-ghw.
let's try it.

The `chill_other` call is the only staking call that explicitly requires
`controller` in its signature. This PR changes the controller arg to be
the stash instead, with `StakingLedger` then fetching the controller
from storage.

This is not a breaking change per se - the call types do not change, but
is noteworthy as UIs will now want to pass the stash account into
`chill_other` calls, & metadata will reflect this.

Note: This is very low impact. `chill_other` has [hardly ever been
used](https://polkadot.subscan.io/extrinsic?address=&module=staking&call=chill_other&result=all&signedChecked=signed%20only&startDate=&endDate=&startBlock=&timeType=date&version=9431&endBlock=)
on Polkadot - notwithstanding the one called 11 days ago at block
18177457 that was a part of test I did, the last call was made 493 days
ago. Only 2 calls have ever been successful.

compiled in a way that is compatible with our executor, however this
doesn't affect Rust's standard library crates (`std`, `core` and
`alloc`) which are by default precompiled and still can make use of
these extra features.

So in this PR we force the compiler to also compile the standard library
crates for us to make sure that they also only use the MVP features.

I've added the `WASM_BUILD_STD` environment variable which can be used
to disable this behavior if set to `0`.

Unfortunately this *will* slow down the compile times when building
runtimes, but there isn't much that we can do about that.
