* Runtime API versioning
Related to issue #11577
Add support for multiple versions of a Runtime API. The purpose is to
have one main version of the API, which is considered stable and
multiple unstable (aka staging) ones.
How it works
===========
Some methods of the API trait can be tagged with `#[api_version(N)]`
attribute where N is version number bigger than the main one. Let's call
them **staging methods** for brevity.
The implementor of the API decides which version to implement.
Example (from https://github.com/paritytech/substrate/issues/11577#issuecomment-1145347025):
```
decl_runtime_apis! {
#{api_version(10)]
trait Test {
fn something() -> Vec<u8>;
#[api_version(11)]
fn new_cool_function() -> u32;
}
}
```
```
impl_runtime_apis! {
#[api_version(11)]
impl Test for Runtime {
fn something() -> Vec<u8> { vec![1, 2, 3] }
fn new_cool_function() -> u32 {
10
}
}
}
```
Version safety checks (currently not implemented)
=================================================
By default in the API trait all staging methods has got default
implementation calling `unimplemented!()`. This is a problem because if
the developer wants to implement version 11 in the example above and
forgets to add `fn new_cool_function()` in `impl_runtime_apis!` the
runtime will crash when the function is executed.
Ideally a compilation error should be generated in such cases.
TODOs
=====
Things not working well at the moment:
[ ] Version safety check
[ ] Integration tests of `primitives/api` are messed up a bit. More
specifically `primitives/api/test/tests/decl_and_impl.rs`
[ ] Integration test covering the new functionality.
[ ] Some duplicated code

* Address simple review comments
* client/beefy: don't accept vote for older rounds
* client/beefy: clean up and reorg the worker struct
* client/beefy: first step towards Full BEEFY
The first step from Lean->Full BEEFY is to have the worker
enforce uninterrupted line of BEEFY finalized mandatory blocks.
There is one mandatory block per session (the first block in the
session). As such, votes processing and votes generation now
enforces that all mandatory blocks are finalized in strict
monotonically increasing sequence and no block 'N' will be worked
on if there is any GRANDPA finalized but BEEFY non-final mandatory
block 'M', where 'M < N'.
Implementation details:
- Introduced 'VoterOracle' to separate the voting decisions logic,
and track new/pending sessions.
- New sessions get queued up with the worker operating either:
1. up-to-date - all mandatory blocks leading up to current GRANDPA
finalized: queue has ONE element, the 'current session' where
`mandatory_done == true`,
2. lagging behind GRANDPA: queue has [1, N] elements, where all
`mandatory_done == false`.
In this state, everytime a session gets its mandatory block
BEEFY finalized, the session is popped off the queue,
eventually getting to operating mode `1. up-to-date`.
- Votes get triaged and those that fall withing the `VoterOracle`
allowed window get processed, the others get dropped if stale,
or buffered for later processing (when they reach the window).
- Worker general code was also updated to fall in one of two roles:
1. react to external events and change internal 'state',
2. generate events/votes based on internal 'state'.

* simplify leaf_node_index_to_leaf_index
summing the (shifted) differences in peak positions adds up to the (shifted) final position, so

* dead fish: this also doesn't work
The idea was to keep a rolling window of `(parent_hash, pos)` leaf
entries in the offchain db, with the window matching the one
that provides `block_num -> block_hash` mappings in `frame_system`.
Once a leaf exits the window it would be "canonicalized" by switching
its offchain db key from `(parent_hash, pos)` to simple `pos`.
This doesn't work however because there's no way to get leaf contents
from offchain db while in runtime context.. so no way to get+clear+set
leaf to change its key in offchain db.
Ideas:
1. move the "canonicalization" logic to offchain worker
2. enhance IndexingApi with "offchain::move(old_key, new_key)"
This is weird, but correct, deterministic and safe AFAICT, so
it could be exposed to runtime.

* pallet-beefy: add Config::OnNewValidatorSet type
Add a hook to pallet-beefy for doing specific work when
BEEFY validator set changes.
For example, this can be used by pallet-beefy-mmr to cache
a lightweight MMR root over validators and make it available
to light clients.
* pallet-beefy-mmr: implement OnNewValidatorSet
Implement pallet-beefy::OnNewValidatorSet to be notified of BEEFY
validator set changes. Use the notifications to compute and cache
a light weight 'BEEFY authority set' which is an MMR root over
BEEFY validator set plus some extra info.
Previously, pallet-beefy-mmr was interogating pallet-beefy about
validator set id on every block to find out when it needs to recompute
the authority set.
By using the event-driven approach in this commit, we also save one
extra state interogation per block.
* pallet-beefy-mmr: add new authority_set() API
Expose current and next BEEFY authority sets through runtime API.
These can be directly used by light clients to avoid having them
compute them themselves based on BEEFY validator sets.
