Shouldn't say: ancestor = chain.GetHeader(ancestor.ParentHash, ancestor.Number.Uint64()-1)?
Or also ancestor = chain.GetHeader(ancestor.ParentHash, i-1)

This is a rewrite of eip 2935 after it was suggested to simply insert all block hash values at fork time, instead of reading the 256th ancestor and using a complex fallback mechanism.
