* Implement basic equivocations detection loop (#2367) * FinalityProofsBuf adjustments - store a Vec<FinalityProof> - transform prune `buf_limit` to Option * FinalityProof: add target_header_hash() * Target client: implement best_synced_header_hash() * Implement first version of the equivocations detection loop * Address code review comments * Leftover * polkadot-staging adjustments
