Implement this to subscribe to events generated in validation.
Each CValidationInterface() subscriber will receive event callbacks in the order in which the events were generated by validation. Furthermore, each ValidationInterface() subscriber may assume that callbacks effectively run in a single thread with single-threaded memory consistency. That is, for a given ValidationInterface() instantiation, each callback will complete before the next one is invoked. This means, for example when a block is connected that the UpdatedBlockTip() callback may depend on an operation performed in the BlockConnected() callback without worrying about explicit synchronization. No ordering should be assumed across ValidationInterface() subscribers.

Protected destructor so that instances can only be deleted by derived classes.
If that restriction is no longer desired, this should be made public and virtual.

Notifies listeners of a block validation result.
If the provided BlockValidationState IsValid, the provided block is guaranteed to be the current best block at the time the callback was generated (not necessarily now)

Provides a vector of transactions evicted from the mempool as a result.

Notifies listeners of the new active block chain on-disk.
Prior to this callback, any updates are not guaranteed to persist on disk (ie clients need to handle shutdown/restart safety by being able to understand when some updates were lost due to unclean shutdown).
When this callback is invoked, the validation changes done by any prior callback are guaranteed to exist on disk and survive a restart, including an unclean shutdown.
Provides a locator describing the best chain, which is likely useful for storing current state on disk in client DBs.
Called on a background thread.
Reimplemented in BaseIndex.

Notifies listeners of a transaction leaving mempool.
This notification fires for transactions that are removed from the mempool for the following reasons:
This does not fire for transactions that are removed from the mempool because they have been included in a block. Any client that is interested in transactions removed from the mempool for inclusion in a block can learn about those transactions from the BlockConnected notification.
Transactions that are removed from the mempool because they conflict with a transaction in the new block will have TransactionRemovedFromMempool events fired before the BlockConnected event is fired. If multiple blocks are connected in one step, then the ordering could be:

Notifies listeners when the block chain tip advances.
When multiple blocks are connected at once, UpdatedBlockTip will be called on the final tip but may not be called on every intermediate tip. If the latter behavior is desired, subscribe to BlockConnected() instead.
