* Add stub for checkDoubleSpends

* Revert "Rename isHighPriority to neverExpires"

This reverts commit b2da9a4a00c02fb380d2518cf54fa16257bd8423.

* Implement removeTransaction, remove sanity checks

* Implemented mempoolUTXOSet.checkDoubleSpends

* Implemented removeOrphan

* Implement removeOrphan

* Implement maybeAddOrphan and AddOrphan

* Implement validateTransaction functions

* Implement fillInputs

* Implement ValidateAndInsertTransaction

* Implement HandleNewBlockTransactions

* Implement missing mempool interface methods

* Add comments to exported functions

* Implement RevalidateHighPriorityTransactions

* Rewire kaspad to use new mempool, and fix compilation errors

* Update rebroadcast logic to use new structure

* Handle non-standard transaction errors properly

* Add mutex to mempool

* bugfix: GetTransaction panics when ok is false

* properly calculate targetBlocksPerSecond in config.go

* Fix various lint errors and tests

* Fix expected text in test for duplicate transactions

* Skip the coinbase transaction in HandleNewBlockTransactions

* Unorphan the correct transactions

* Call ValidateTransactionAndPopulateWithConsensusData on unorphanTransaction

* Re-apply policy_test as check_transactions_standard_test

* removeTransaction: Remove redeemers in orphan pool as well

* Remove redundant check for uint64 < 0

* Export and rename isDust -> IsTransactionOutputDust to allow usage by rothschild

* Add allowOrphan to SubmitTransaction RPC request

* Remove all implementation from mempool.go

* tidy go mod

* Don't pass acceptedOrphans to handleNewBlockTransactions

* Use t.Errorf in stead of t.Fatalf

* Remove minimum relay fee from TestDust, as it's no longer configurable

* Add separate VirtualDAASCore method for faster retrieval where it's repeated multiple times

* Broadcast all transactions that were accepted

* Don't re-use GetVirtualDAAScore in GetVirtualInfo - this causes a deadlock

* Use real transaction count, and not Orphan

* Get mempool config from outside, incorporating values received from cli

* Use MinRelayFee and MaxOrphanTxs from global kaspad config

* Add explanation for the seemingly redundant check for transaction version in checkTransactionStandard

* Update some comment

* Convert creation of acceptedTransactions to a single line

* Move mempoolUTXOSet out of checkDoubleSpends

* Add test for attempt to insert double spend into mempool

* fillInputs: Skip check for coinbase - it's always false in mempool

* Clarify comment about removeRedeemers when removing random orphan

* Don't remove high-priority transactions in limitTransactionCount

* Use mempool.removeTransaction in limitTransactionCount

* Add mutex comment to handleNewBlockTransactions

* Return error from limitTransactionCount

* Pluralize the map types

* mempoolUTXOSet.removeTransaction: Don't restore utxo if it was not created in mempool

* Don't evacuate from orphanPool high-priority transactions

* Disallow double-spends in orphan pool

* Don't use exported (and locking) methods from inside mempool

* Check for double spends in mempool during revalidateTransaction

* Add checkOrphanDuplicate

* Add TestHighPriorityTransactions

* Fix off-by-one error in limitTransactionCount

* Add TestRevalidateHighPriorityTransactions

* Remove checkDoubleSpends from revalidateTransaction

* Fix TestRevalidateHighPriorityTransactions

* Move check for MaximumOrphanCount to beggining of maybeAddOrphan

* Rename all map type to singulateToSingularMap

* limitOrphanPool only after the orphan was added

* TestDoubleSpendInMempool: use createChildTxWhenParentTxWasAddedByConsensus instead of createTransactionWithUTXOEntry

* Fix some comments

* Have separate min/max transaction versions for mempool

* Add comment on defaultMaximumOrphanTransactionCount to keep it small as long as we have recursion

* Fix comment

* Rename: createChildTxWhenParentTxWasAddedByConsensus -> createChildTxWhereParentTxWasAddedByConsensus

* Handle error from createChildTxWhereParentTxWasAddedByConsensus

* Rename createChildTxWhereParentTxWasAddedByConsensus -> createChildAndParentTxsAndAddParentToConsensus
