* Make AncestryProof type more flexible
* Only import single finalized header instead of a chain
* Fix unchecked header import tests
* Add option for limiting ancestry proof size
* Update finality verifier Config in runtimes
* Update some documentation
* Fix Clippy warning
* Allow AncestryChecker to return proof size
Stops us from abusing the `Size` trait
* Remove Size impl for Vec<T>
* Remove size contraints for ancestry proofs
With different proof types its unclear how to "size" should be interpreted,
so we remove this requirement all together to avoid confusion.
* Add Finality Verifier pallet to runtimes
* Implement simple ancestry checker
* Use the new checker in runtimes
* Remove unused import warning
* Bump max allowed ancestry proof size
* Add a few optimization suggestions when verifying ancestry
* Use session length as upper bound for ancestry proof size
* Remove unused time units
* Add skeleton for `pallet-finality-verifier`
* Sketch out implementation for importing finality proofs
* Get pallet compiling
* Introduce skeleton for mock runtime
* Start using real Grandpa types in finality pallet
* Redefine types in header chain primitives crate
* Implement HeaderChain for Substrate bridge pallet
* Plug Substrate Bridge Pallet into verifier mock
* Fix compilation of `header-chain` primitives
* Start writing to base pallet storage
* Add first "cross-pallet" test
* Move keyring primitives used in tests to shared crate
* Stop pulling `std` deps into `no_std` builds
* Revert "Stop pulling `std` deps into `no_std` builds"
This reverts commit f74dd660652f98b7336936d1534a4e63cc9169a5.
* Revert "Move keyring primitives used in tests to shared crate"
This reverts commit b774fa730b2cdc40545afff308a66b0840266001.
* Use new SS58Prefix type in mock
* Start using `bp-test-utils` in finality pallet
* Start using real justification code
* Get a test working with real justification verification
* Add basic tests for invalid proofs
* Get rid of AncestryProof config type
* Add error types to transaction outcome
* Bound number of headers allowed in a single ancestry proof
* Disallow invalid authority sets
* Remove unused items
* Add some documentation
* Get rid of Clippy warnings
* Rename BaseHeaderChain to TransactionVerifier
* Remove unused code
