This commit adds a new set providing storage for two IP addresses and two ports. The most common use case for this is matching a source IP+port to a destination IP+port. Ranges of ports are supported using the logic that every port in range A (the second argument) will have an entry created for all values in range B (the fourth argument) For example: ipset add 1.1.1.1,11-12,2.2.2.2,13-14 Will result in: * 1.1.1.1,11,2.2.2.2,13 * 1.1.1.1,11,2.2.2.2,14 * 1.1.1.1,12,2.2.2.2,13 * 1.1.1.1,12,2.2.2.2,14 Tests have been added to verify the functionality.
