Increments the global transaction ID and returns the new value.

Initializes the node

Inserts a slot for one additional record

Inserts a slot at the position |slot|. |node_count| is the number of used slots (this is managed by the caller)

Inserts a key/record pair in a txn node; if cursor is not NULL it will be attached to the new txn_op structure
