* Use selectedParent instead of selectedTip for non-selectedTip blocks in restoreSingleBlockStatus * Cache the selectedParent for re-use in a resolveSingleBlockStatus chain * Implement and use reverseUTXOSet * Reverse blocks in correct order * Support resolveBlockStatus without separate stagingAreas for usage of testConsensus * Handle the case where the tip of the resolved block is not the next selectedTip * Unify isResolveTip * Some minor fixes and cleanup * Add full finality window re-org test to stability-slow * rename: useSeparateStagingAreasPerBlock -> useSeparateStagingAreaPerBlock * Better logs in resolveSingleBlockStatus * A few retouches to reverseUTXODiffs * TEMPORARY COMMIT: EXTRAT ALL DIFFFROMS TO SEPARATE METHODS * TEMPORARY COMMIT: REMOVE DIFFICULTY CHECKS IN DEVNET * Don't pre-allocate in utxo-algebra, since the numbers are not known ahead-of-time * Add some logs to reverseUTXODiffs * Revert "TEMPORARY COMMIT: REMOVE DIFFICULTY CHECKS IN DEVNET" This reverts commit c0af9dc6ade78a914c970e11bc63c34605565f57. * Revert "TEMPORARY COMMIT: EXTRAT ALL DIFFFROMS TO SEPARATE METHODS" This reverts commit 4fcca1b48c3a1183598833a355b9bfaf169edba1. * Remove redundant paranthesis * Revise some logs messages * Rename:oneBlockBeforeCurrentUTXOSet -> lastResolvedBlockUTXOSet * Don't break if the block was resolved as invalid * rename unverifiedBlocks to recentlyVerifiedBlcks in reverseUTXODiffs * Add errors.New to the panic, for a stack trace * Reverse the UTXODiffs after the main block has been commited * Use the correct value for previousUTXODiff * Add test for ReverseUTXODiff * Fix some names and comments * Update TestReverseUTXODiffs to use consensus.Config * Fix comments mentioning 'oneBlockBeforeTip'
