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>,
+ >,
```

See #1345, <https://github.com/paritytech/substrate/pull/14207>.
This adds all the necessary mixnet components, and puts them together in
the "kitchen-sink" node/runtime. The components added are:
- A pallet (`frame/mixnet`). This is responsible for determining the
current mixnet session and phase, and the mixnodes to use in each
session. It provides a function that validators can call to register a
mixnode for the next session. The logic of this pallet is very similar
to that of the `im-online` pallet.
- A service (`client/mixnet`). This implements the core mixnet logic,
building on the `mixnet` crate. The service communicates with other
nodes using notifications sent over the "mixnet" protocol.
- An RPC interface. This currently only supports sending transactions
over the mixnet.

* More extensible multiaddress format
* update name
* Don't depend on indices to define multiaddress type
* Use MultiAddress in Node Template too!
* reduce traits, fix build
* support multiple `StaticLookup`
* bump tx version
* feedback
* Add ‘transaction_version’ to the signed transaction
This allows hardware wallets to know which transactions they can safely
sign. To reduce transaction size, I reduced it to a ‘u8’ from a ‘u32’.
Fixes#5951.
* Restore transaction_version to a u32
* Fix comments
`transaction_version` is not part of a tx, but is still signed.

code.
