syncer: avoid attacked by older AgreementResult when syncing (#471)
One possible attack for syncer is:
- byzantine nodes periodically broadcast some very
old types.AgreementResults.
- If some syncer receive those
types.AgreementResult, they might synced
directly while still fall behind other nodes.
A quick workaround is ignore
types.AgreementResults older than the chain tip
when creating the syncer.Consensus instance.
