* Get rid of insertMode * Rename AddBlockToVirtual->AddBlock * When F is not in the future of P, enforce finality with P and not with F. * Don't allow blocks with invalid parents or with missing block body * Check finality violation before checking block status * Implement CalculateIndependentPruningPoint * Move checkBlockStatus to validateBlock * Add ValidateBlock to block processor interface * Adjust SetPruningPoint to the new IBD flow * Add pruning store to CSM's constructor * Flip wrong condition on AddHeaderTip * Fix func (hts *headerSelectedTipStore) Has * Fix block stage order * Call to ValidateBodyInContext from validatePostProofOfWork * Enable overrideDAGParams * Update log * Rename SetPruningPoint to ValidateAndInsertPruningPoint and move most of its logic inside block processor * Rename hasValidatedHeader->hasValidatedOnlyHeader * Fix typo * Name return values for fetchMissingUTXOSet * Add comment * Return ErrMissingParents when block body is missing * Add logs and comments * Fix merge error * Fix pruning point calculation to be by virtual selected parent * Replace CalculateIndependentPruningPoint to CalculatePruningPointByHeaderSelectedTip * Fix isAwaitingUTXOSet to check pruning point by headers * Change isAwaitingUTXOSet indication * Remove IsBlockInHeaderPruningPointFuture from BlockInfo * Fix LowestChainBlockAboveOrEqualToBlueScore * Add validateNewPruningPointTransactions * Add validateNewPruningAgainstPastUTXO * Rename set_pruning_utxo_set.go to update_pruning_utxo_set.go * Check missing block body hashes by missing block instead of status * Validate pruning point against past UTXO with the pruning point as block hash * Remove virtualHeaderHash * Fix comment * Fix imports
