* Calculate GHOSTDAG, reachability etc for each level * Don't preallocate cache for dag stores except level 0 and reduce the number of connections in the integration test to 32 * Reduce the number of connections in the integration test to 16 * Increase page file * BuildPruningPointProof * BuildPruningPointProof * Add PruningProofManager * Implement ApplyPruningPointProof * Add prefix and fix blockAtDepth and fill headersByLevel * Some bug fixes * Include all relevant blocks for each level in the proof * Fix syncAndValidatePruningPointProof to return the right block hash * Fix block window * Fix isAncestorOfPruningPoint * Ban for rule errors on pruning proof * Find common ancestor for blockAtDepthMAtNextLevel * Use pruning proof in TestValidateAndInsertImportedPruningPoint * stage status and finality point for proof blocks * Uncomment golint * Change test timeouts * Calculate merge set for ApplyPruningPointProof * Increase test timeout * Add better caching for daa window store * Return to default timeout * Add ErrPruningProofMissesBlocksBelowPruningPoint * Add errDAAWindowBlockNotFound * Force connection loop next iteration on connection manager stop * Revert to Test64IncomingConnections * Remove BlockAtDepth from DAGTraversalManager * numBullies->16 * Set page file size to 8gb * Increase p2p max message size * Test64IncomingConnections->Test16IncomingConnections * Add comment for PruningProofM * Add comment in `func (c *ConnectionManager) Stop()` * Rename isAncestorOfPruningPoint->isAncestorOfSelectedTip * Revert page file to 16gb * Improve ExpectedHeaderPruningPoint perf * Fix comment * Revert "Improve ExpectedHeaderPruningPoint perf" This reverts commit bca1080e7140c78d510f51bbea858ae280c2f38e. * Don't test windows
