Remove hardcoded maximum for lists

[FOSSLGYS]

List class has a maximum limit on the data to be supported. Remove the maximum.

Does the list have a maximum? I see in the list class there is a listData array that is sized at MAX_ENTRIES (500). Is this the hardcoded maximum you are referring to? I think this has not actually imposed a maximum on the list because the only time listData is added to is when setNextData is called, but setNextData is not called on the list class. Are there other constraints that would cause the list to have an upperbound?
