Re-applying #2302 after increasing the `MaxPageSize`.  

Remove `without_storage_info` from the XCMP queue pallet. Part of
https://github.com/paritytech/polkadot-sdk/issues/323

Changes:
- Limit the number of messages and signals a HRMP channel can have at
most.
- Limit the number of HRML channels.

A No-OP migration is put in place to ensure that all `BoundedVec`s still
decode and not truncate after upgrade. The storage version is thereby
bumped to 5 to have our tooling remind us to deploy that migration.

## Integration

If you see this error in your try-runtime-cli:  
```pre
Max message size for channel is too large. This means that the V5 migration can be front-run and an
attacker could place a large message just right before the migration to make other messages un-decodable.
Please either increase `MaxPageSize` or decrease the `max_message_size` for this channel. Channel max:
102400, MaxPageSize: 65535
```

Then increase the `MaxPageSize` of the `cumulus_pallet_xcmp...

As per #3326, removes pallet::getter usage from the bounties and
child-bounties pallets. The syntax `StorageItem::<T, I>::get()` should
be used instead.

Changes to one pallet involved changes in the other, so I figured it'd
be best to combine these two.

`cumulus-pallet-dmp-queue` is not needed anymore since
https://github.com/paritytech/polkadot-sdk/pull/1246.

The only logic that remains in the pallet is a lazy migration in the
[`on_idle`](https://github.com/paritytech/polkadot-sdk/blob/8d62c13b

/cumulus/pallets/dmp-queue/src/lib.rs#L158)
hook.

Fix after https://github.com/paritytech/polkadot-sdk/pull/4449

# Context

XCM docs are currently an md book hosted with github pages:
https://paritytech.github.io/xcm-docs/.
While that's fine, it's not in line with the work being done in the
polkadot-sdk docs.

# Main addition

This PR aims to fix that by bringing the docs back to this repo.
This does not have all the information currently present in the mdbook
xcm-docs but aims to be a good chunk of it and fully replace it over
time.

I also added the sections `guides` and `cookbook` which will be very
useful for users wanting to get into XCM.
For now I only added one example to the cookbook, but have ideas for
guides and more examples.
Having this docs be in rust docs is very useful for the cookbook.

# TODO

- [x] Use `FungibleAdapter`
- [x] Improve and relocate mock message queue
- [x] Fix license issue. Why does docs/sdk/ not have this problem? (Just
added the licenses)

# Next steps

- More examples in the cookbook
- End-to-end XCM guide with zombienet testing

Dear team, hello, 

Please consider this request to add bootnode endpoints to the chainspecs
of `coretime-westend` and `coretime-kusama`.

These bootnodes are operated by the Infrastructure Builders Programme as
part of the commitments of their members.

All these endpoints have been tested according to the procedure
indicated
[here](https://wiki.ibp.network/docs/consumers/bootnodes#testing-a-bootnode).

Additionally, please also consider some maintenance changes to
Gatotech's bootnode endpoint in several other chains.

Many thanks!!

Best regrds!

This is for adding onfinality polkadot bootnode. Please correct me if
this is not the right place for adding a new bootnode

This is the second PR in preparation for
https://github.com/paritytech/polkadot-sdk/issues/454.

## Also see
- **Precursor** https://github.com/paritytech/polkadot-sdk/pull/3889.
- **Follow up** https://github.com/paritytech/polkadot-sdk/pull/3905.

Overall changes are documented here (lot more visual 

):
https://hackmd.io/@ak0n/454-np-governance

## Changes
### Delegation Interface
Provides delegation primitives for staking. 

Introduces two new roles:
- Agent: These are accounts who receive delegation from other accounts
(delegators) and stakes on behalf of them. The funds are held in
delegator accounts.
- Delegator: Accounts who delegate their funds to an agent authorising
them to use it for staking.

Supports
- A way for delegators to add or withdraw delegation to an agent.
- A way for an agent to slash a delegator during a slashing event.

### Pallet Delegated Staking
- Implements `DelegationInterface`.
- Lazy slashing: Any slashes to an Agent is posted in a ledger but not
immediately slashed. The agent can call
`DelegationInterface::delegator_slash` to slash the member and clear the
corresponding slash from its ledger.
- Consumes `StakingInterface` to provide `CoreStaking` features. In
reality, this will be `pallet-staking`.
- Ensures bookkeeping for agent and delegator are correct but leaves the
management of reward and slash logic upto the consumer of this pallet.
- While it does not expose any calls yet, it is written with the intent
of exposing these primitives via extrinsics.

## TODO
- [x] Improve unit tests in the pallet.
- [x] Separate slash reward perbill for rewarding the slash reporters?
- [x] Review if we should add more events.

This PR changes the fork calculation and pruning algorithm to enable
future block header pruning. It's required because the previous
algorithm relied on the block header persistence. It follows the
[related
discussion](https://github.com/paritytech/polkadot-sdk/issues/1570)

The previous code contained this comment describing the situation:
```
	/// Note a block height finalized, displacing all leaves with number less than the finalized
	/// block's.
	///
	/// Although it would be more technically correct to also prune out leaves at the
	/// same number as the finalized block, but with different hashes, the current behavior
	/// is simpler and our assumptions about how finalization works means that those leaves
	/// will be pruned soon afterwards anyway.
	pub fn finalize_height(&mut self, number: N) -> FinalizationOutcome<H, N> {
```

The previous algorithm relied on the existing block headers to prune
forks later and to enable block header pruning we need to clear all
obsolete forks right after the block finalization to not depend on the
related block headers in the future.

A small step towards
https://forum.polkadot.network/t/polkadot-parachain-omni-node-gathering-ideas-and-feedback/7823
and #4352.

Many parachains use `camelCase` and/or `PascalCase`ing for their chain
spec extension. Sometimes the only reason polkadot-parachain cannot sync
them is because it cannot parse the chain spec extension. This PR
relaxes the requirement for the extension to be camel case.

Github currently [doesn't support creating
subfolders](https://github.com/orgs/community/discussions/18055) in
`.github/workflows` folder. PR unifies naming in this folder. The idea
is that all files ideally should have naming
`<stage>-<short_descriptive_name>.yml`. The stage names are taken from
gitlab and needed only for logical division.
Changes in actions:
 - `check-licences` runs on self-hosted runners
- `check-workspace` and `check-markdown` are moved to `checks-quick.yml`
 - `test-linux-stable-int` moved to a new file `tests-linux-stable.yml`
- `fmt-check.yml` file is removed, formatting is checked in
`checks-quick.yml`

`*-host` and `*-port` are obsolete and we'll hopefully remove them in
the future (already WIP for Rococo <> Westend relayer)

Support async backing in `--dev` mode

This PR improve the relay mock `MockValidationDataInherentDataProvider`
to mach expectations of async backing runtimes.

* Add para_head in the mock relay proof
* Add relay slot in the mock relay proof 

fix https://github.com/paritytech/polkadot-sdk/issues/4437

This PR bumps `proc-macro-crate` to the latest version.

In order to test a runtime from
https://github.com/polkadot-fellows/runtimes/ with the latest version of
polkadot-sdk one needs to use `cargo vendor` to extract all runtime
dependencies, patch them by hand and then build the runtime.

However at the moment 'vendored' builds fail due to
https://github.com/bkchr/proc-macro-crate/issues/48. To fix this
`proc-macro-crate` should be updated to version `3.0.1` or higher.

Reworks prospective-parachains so that we allow a number of unconnected
candidates (for which we don't know the parent candidate yet). Needed
for elastic scaling:
https://github.com/paritytech/polkadot-sdk/issues/3541. Without this,
candidate B will not be validated and backed until candidate A (its
parent) is validated and a backing statement reaches the validator.

Due to the high complexity of the subsystem, I rewrote parts of it so
that we don't concern ourselves with candidates which form cycles or
which form parachain forks. We now have "Fragment chains" instead of
"Fragment trees". This greatly simplifies some of the code and is a
compromise we can make. We just need to make sure that cycle-producing
parachains don't brick the relay chain and that fork-producing
parachains can still make some progress (on one core at least). The only
forks that are allowed are those on the relay chain, obviously.

Unconnected candidates are kept in the `CandidateStorage` and whenever a
new candidate is introduced, we try to repopulate the chain with as many
candidates as we can.

Also fixes https://github.com/paritytech/polkadot-sdk/issues/3219

Guide changes will be done as part of:
https://github.com/paritytech/polkadot-sdk/issues/3699

TODOs:

- [x] see if we can replace the `Cow` over the candidate commitments
with an `Arc` over the entire `ProspectiveCandidate`. It's only being
overwritten in unit tests. We can work around that.
- [x] finish fragment_chain unit tests
- [x] add more prospective-parachains subsystem tests
- [x] test with zombienet what happens if a parachain is creating cycles
(it should not brick the relay chain).
- [x] test with zombienet a parachain that is creating forks. it should
keep producing blocks from time to time (one bad collator should not DOS
the parachain, even if throughput decreases)
- [x] add some more logs and metrics
- [x] add prdoc and remove the "silent" label

Currently the `CheckWeight` `SignedExtension` was tracking the size of
the proof and the extrinsic length separately. But in reality we need
one more check that ensures we don't hit the PoV limit with both
combined.

The rest of the logic remains unchanged. One scenario where the changes
make a difference is when we enter this branch:

https://github.com/paritytech/polkadot-sdk/blob/f34d8e3c

/substrate/frame/system/src/extensions/check_weight.rs#L185-L198

This was previously allowing to some extrinsics that is exceeding the
block limit but are withing the reserved area of `BlockWeights`. This
will now be caught by the later check I introduced. I think the new
behaviour makes sense, since the proof size dimension is designed for
parachains and they don't want to go over the limit and get rejected.


In the long run we should maybe get rid of `RuntimeBlockLength`
alltogether, however that would require a deprecation process and can
come at a later point.

Library `substrate-frame-cli` seems unused.

Last non-dependabot update to the folder was over [two years
ago](https://github.com/paritytech/polkadot-sdk/commits/master/substrate/utils/frame/frame-utilities-cli).

#### Problem
`take()` consumes only 1 read worth of weight in
`single-block-migrations` example, while `take()`
[is](https://github.com/paritytech/polkadot-sdk/blob/master/substrate/frame/support/src/storage/unhashed.rs#L63)
`get() + kill()`, i.e should be 1 read + 1 write. I think this could
mislead developers who follow this example to write their migrations

The block header is required to derive inherents for a relay chain next
block, this is useful in testing environments.

As per #3326, removes pallet::getter usage from the pallet
authority-discovery. The syntax `StorageItem::<T, I>::get()` should be
used instead.

A part of #3326 

Removes all #[pallet::getter] usage from the contracts mock network
pallet. As the storage values were pub(super), read-only visibility was
lost external to the crate upon the removal of the macros. I have
implemented custom getters as a replacement, keeping the api the same.

If we care very much about consistency of the
storagevalue::<T>::get() syntax, the other option would be to set
the storage values to pub. Though I find preserving data authority
better myself.

@muraca

The fact that this takes two sessions to come into effect is not
obvious. Just added some docs to explain that.

Also tidied up uses of "broker chain" -> "coretime chain"

Closes #1961

Disable logging of rustls to get rid off the following log lines:
```
Sending fatal alert BadCertificate
```

Upstream also removed them: https://github.com/rustls/rustls/pull/1278
