* Remove the limit on the amount of hashes returned from antiPastHashesBetween. * Guard against requests with a non-existing block hash. * Move missing-block-hash guards to consensus.go. * Ban a peer that doesn't send us all the requested headers during IBD. * Extract blockHeap.ToSlice. * Re-request headers in requestHeaders if we didn't receive the highHash.
