1676ecd7a6
This commit makes a slight variant of the existing checkConnectBlock function available to external callers. The new exported version checks if the passed block will connect to the end of the current main chain. In order to support this, a few other small modifications have been made to the initial index generation and the existing checkConnectBlock since it previously made some assumptions about the state of genesis block which can no longer be assumed due accepting blocks from callers directly. Also, add a quick test to ensure the new function fails when checking if the genesis block will connect again when it's already inserted.
