Fix for more leaks in NATable
Fix for more leaks in NATable

Added code to delete more elements in NATable destructor. This
fixes leaks when NATable is destroyed.

Changed the NATable Cache Management to use allocated size rather
than the total size.

This also enables seabase/TEST020 to pass in debug mode.
