This requires PR #1229.
This modifies the code that determines the most recently known checkpoint to take advantage of recent changes which make the entire block index available in memory by only storing a reference to the specific node in the index that represents the latest known checkpoint.
Previously, the entire block was stored and new checkpoints required loading it from the database.
This is work towards #1145.
