* 1) Calculate pruning point incrementally 2) Add IsValidPruningPoint to pruning manager and consensus 3) Use reachability children for selected child iterator * Add request IBD root hash flow * Fix UpdatePruningPointByVirtual and IsValidPruningPoint * Regenerate messages.pb.go * Make the pruning point the earliest chain block with finality interval higher than the previous pruning point * Fix merge errors
