Amends some staking pallet docs, and deprecation comment, to adjust to
the latest controller deprecation state.
Note, do we need the `README.md` file, which is a duplicate of the
pallet docs? Docs would be easier to maintain, and less ambiguity for
devs to refer to, if we had one source of truth in the generated pallet
docs.
This moves the macro related re-exports to `__private` to make it more
obvious for downstream users that they are using an internal api.

Westend Asset Hub currently failing because the spec name is being
changed next runtime upgrade
(https://gitlab.parity.io/parity/mirrors/polkadot-sdk/-/jobs/4413125).
This also fixes an idempotency issue with a staking pallet migration.
Similar issues will be caught automatically now that we've also updated
to try-runtime-cli v0.5.0 which checks for idempotency issues.
This also enables try-state checks running in the CI.
This PR removes `#[macro_use]` from the service module in each of the

IDK why this annotation was present, maybe from when we had the

The `SkipCheckifFeeless::IDENTIFIER` became transparent (ie was whatever
the inner signed ext was). This PR just makes the `TypeInfo` transparent
too, so that libraries that use said info to decode the data (ie subxt)
can behave identically whether or not the `SkipCheckifFeeless` wrapper
is used or not.

The `lazy_static` package does not work well in `no-std`: it requires
`spin_no_std` feature, which also will propagate into `std` if enabled.
This is not what we want.
This PR provides simple address uri parser which allows to get rid of
_regex_ which was used to parse the address uri, what in turns allows to
remove lazy_static.
Three regular expressions
(`SS58_REGEX`,`SECRET_PHRASE_REGEX`,`JUNCTION_REGEX`) were replaced with
the parser which unifies all of them.
The new parser does not support Unicode, it is ASCII only.

We need this in order to avoid skipping blocks.
- avoid reprocessing the old state when not necessary
Addresses a bug caused by
https://github.com/paritytech/polkadot-sdk/pull/1189. The changes are
still not released yet, so would like to push the fix soon so it can go
together with the release of the above PR.
`fast_unstake` checks if a staker is exposed in an era. However, this fn
is still returning whether the staker is exposed based on the old
storage item. This PR fixes that by looking in both old and new exposure
storages.
Also adds some integrity tests for paged exposures.
Adds a function for querying the last runtime upgrade spec version. This
can be useful for when writing runtime level migrations to ensure that
they are not executed multiple times. An example would be a session key
migration.

The goal of this PR is to migrate Identity deposits from the Relay Chain
to a system parachain.
The problem I want to solve is that `IdentityOf` and `SubsOf` both store
an amount that's held in reserve as a storage deposit. When migrating to
a parachain, we can take a snapshot of the actual `IdentityInfo` and
sub-account mappings, but should migrate (off chain) the `deposit`s to
zero, since the chain (and by extension, accounts) won't have any funds
at genesis.
The good news is that we expect parachain deposits to be significantly
lower (possibly 100x) on the parachain. That is, a deposit of 21 DOT on
the Relay Chain would need 0.21 DOT on a parachain. This PR proposes to
migrate the deposits in the following way:
1. Introduces a new pallet with two extrinsics:
- `reap_identity`: Has a configurable `ReapOrigin`, which would be set
to `EnsureSigned` on the Relay Chain (i.e. callable by anyone) and
`EnsureRoot` on the parachain (we don't want identities reaped from
there).
- `poke_deposit`: Checks what deposit the pallet holds (at genesis,
zero) and attempts to update the amount based on the calculated deposit
for storage data.
2. `reap_identity` clears all storage data for a `target` account and
unreserves their deposit.
3. A `ReapIdentityHandler` teleports the necessary DOT to the parachain
and calls `poke_deposit`. Since the parachain deposit is much lower, and
was just unreserved, we know we have enough.
One awkwardness I ran into was that the XCMv3 instruction set does not
provide a way for the system to teleport assets without a fee being
deducted on reception. Users shouldn't have to pay a fee for the system
to migrate their info to a more efficient location. So I wrote my own
program and did the `InitiateTeleport` accounting on my own to send a
program with `UnpaidExecution`. Have discussed an
`InitiateUnpaidTeleport` instruction with @franciscoaguirre . Obviously
any chain executing this would have to pass a `Barrier` for free
execution.

add details in `--dev` flag to tell that it disables local peer
discovery
### Context
When adding automated end-to-end tests, we replaced `--dev` by
```
`--chain=dev`, `--force-authoring`, `--rpc-cors=all`, `--alice`, and `--tmp` flags
```
as stated in the command line documentation. But the tests started
failing due to the nodes connecting to each other.
### Fix
This PR includes additional command line documentation to explain more
in detail what `--dev` flag inludes.
BEEFY ECDSA signatures are on keccak has of the messages. As such we can
not simply call
`EcdsaBlsPair::verify(signature.as_inner_ref(), msg,
self.as_inner_ref())`
because that invokes ecdsa default verification which perfoms blake2
hash which we don't want.
This bring up the second issue makes: This makes `sign` and `verify`
function in `pair_crypto` useless, at least for BEEFY use case.
Moreover, there is no obvious clean way to generate the signature given
that pair_crypto does not exposes `sign_prehashed`. You could in theory
query the keystore for the pair (could you?), invoke `to_raw` and
re-generate each sub-pair and sign using each. But that sounds extremely
anticlimactic and will be frow upon by auditors . So I appreciate any
alternative suggestion.

Fixes https://github.com/paritytech/polkadot-sdk/issues/1725
This PR adds the following changes:
1. An attribute `pallet::feeless_if` that can be optionally attached to
a call like so:
```rust
#[pallet::feeless_if(|_origin: &OriginFor<T>, something: &u32| -> bool {
*something == 0
})]
pub fn do_something(origin: OriginFor<T>, something: u32) -> DispatchResult {
....
}
```
The closure passed accepts references to arguments as specified in the
call fn. It returns a boolean that denotes the conditions required for
this call to be "feeless".
2. A signed extension `SkipCheckIfFeeless<T: SignedExtension>` that
wraps a transaction payment processor such as
`pallet_transaction_payment::ChargeTransactionPayment`. It checks for
all calls annotated with `pallet::feeless_if` to see if the conditions
are met. If so, the wrapped signed extension is not called, essentially
making the call feeless.
In order to use this, you can simply replace your existing signed
extension that manages transaction payment like so:
```diff
- pallet_transaction_payment::ChargeTransactionPayment<Runtime>,
+ pallet_skip_feeless_payment::SkipCheckIfFeeless<
+ Runtime,
+ pallet_transaction_payment::ChargeTransactionPayment<Runtime>,
+ >,
```

Remove the `GRANDPA_AUTHORITIES_KEY` key and its usage. Apparently this
was used in the early days to communicate the grandpa authorities to the
node. However, we have now a runtime api that does this for us. So, this

managed storage item.

Optimizes the `rerun-if-changed` logic by ignoring `dev-dependencies`
and also not outputting paths. Because outputting paths could lead to
include unwanted crates in the rerun checks.
All `ChainSync` actions that `SyncingEngine` should perform are unified
under one `ChainSyncAction`. Processing of these actions put into a
single place after `select!` in `SyncingEngine::run` instead of multiple
places where calling `ChainSync` methods.
A utility function I consider quite useful to declare string literals
that are backed by an array.

These changes are required so that the bridgehub system runtimes can
more easily be configured with multiple message processors
Example usage:
```rust
use frame_support::traits::QueuePausedQuery;
impl pallet_message_queue::Config for Runtime {
type QueuePausedQuery = (A, B, C)
}
When warp syncing we import the target block with all its state.
However, we didn't store the `LAST_PRUNED` block which would then lead
to `pruning` to forget about the imported block after a restart of the
node. We just set `LAST_PRUNED` to the parent block of the warp sync
target block to fix this issue.
Genesis building in runtime may involve calling some custom host
functions. This PR allows to pass `HostFunctions` into the `ChainSpec`
struct, which in turn are passed to `WasmExecutor`. The `ChainSpec` now
has extended host functions type parameter:
```
pub struct ChainSpec<G, E = NoExtension, EHF = ()>
```
which will be combined with the default set
(`sp_io::SubstrateHostFunctions`) in an instance of `WasmExecutor` used
to build the genesis config.

The trie cache implementation was ignoring the `storage_root` when
setting up the value cache. The problem with this is that the value
cache works using `storage_keys` and these keys are not unique across
different tries. A block can actually have different tries (main trie
and multiple child tries). This pull request fixes the issue by not
ignoring the `storage_root` and returning an unique `value_cache` per
`storage_root`. It also adds a test for the seen bug and improves
documentation that this doesn't happen again.
Changes:
- Adds a new call `remove_key` to the sudo pallet to permanently remove
the sudo key.
- Remove some clones and general maintenance

Closes https://github.com/paritytech/polkadot-sdk/issues/109
### Problem
Quoting from the above issue:
> When adding a pallet to chain after genesis we currently don't set the
StorageVersion. So, when calling on_chain_storage_version it returns 0
while the pallet is maybe already at storage version 9 when it was added
to the chain. This could lead to issues when running migrations.
### Solution
- Create a new trait `BeforeAllRuntimeMigrations` with a single method
`fn before_all_runtime_migrations() -> Weight` trait with a noop default
implementation
- Modify `Executive` to call
`BeforeAllRuntimeMigrations::before_all_runtime_migrations` for all
pallets before running any other hooks
- Implement `BeforeAllRuntimeMigrations` in the pallet proc macro to
initialize the on-chain version to the current pallet version if the
pallet has no storage set (indicating it has been recently added to the
runtime and needs to have its version initialised).
### Other changes in this PR
- Abstracted repeated boilerplate to access the `pallet_name` in the
pallet expand proc macro.
### FAQ
#### Why create a new hook instead of adding this logic to the pallet
`pre_upgrade`?
`Executive` currently runs `COnRuntimeUpgrade` (custom migrations)
before `AllPalletsWithSystem` migrations. We need versions to be
initialized before the `COnRuntimeUpgrade` migrations are run, because
`COnRuntimeUpgrade` migrations may use the on-chain version for critical
logic. e.g. `VersionedRuntimeUpgrade` uses it to decide whether or not
to execute.
We cannot reorder `COnRuntimeUpgrade` and `AllPalletsWithSystem` so
`AllPalletsWithSystem` runs first, because `AllPalletsWithSystem` have
some logic in their `post_upgrade` hooks to verify that the on-chain
version and current pallet version match. A common use case of
`COnRuntimeUpgrade` migrations is to perform a migration which will
result in the versions matching, so if they were reordered these
`post_upgrade` checks would fail.
#### Why init the on-chain version for pallets without a current storage
version?
We must init the on-chain version for pallets even if they don't have a
defined storage version so if there is a future version bump, the
on-chain version is not automatically set to that new version without a
proper migration.
e.g. bad scenario:
1. A pallet with no 'current version' is added to the runtime
2. Later, the pallet is upgraded with the 'current version' getting set
to 1 and a migration is added to Executive Migrations to migrate the
storage from 0 to 1
a. Runtime upgrade occurs
b. `before_all` hook initializes the on-chain version to 1
c. `on_runtime_upgrade` of the migration executes, and sees the on-chain
version is already 1 therefore think storage is already migrated and
does not execute the storage migration
Now, on-chain version is 1 but storage is still at version 0.
By always initializing the on-chain version when the pallet is added to
the runtime we avoid that scenario.

@kianenigma
Add infrastructure needed to have a Pallet::decode_entire_state(), which
makes sure all "typed" storage items defined in the pallet are
decode-able.
This is not enforced in any way at the moment. Teams who wish to
integrate/use this in the try-runtime feature flag should add
frame_support::storage::migration::EnsureStateDecodes as the LAST ITEM
of the runtime's custom migrations, and pass it to frame-executive. This
will make it usable in try-runtime on-runtime-upgrade.
This now catches cases like
https://github.com/paritytech/polkadot-sdk/pull/1969:
```pre
ERROR runtime::executive] failed to decode the value at key: Failed to decode value at key: 0x94eadf0156a8ad5156507773d0471e4ab8ebad86f546c7e0b135a4212aace339.
