In order to add new IWPM_NL attributes, the enums for the IWPM commands attributes are refactored such that a new attribute can be added without breaking ABI version 3. Instead of sharing nl attribute enums for both request and response messages, we create separate enums for each IWPM message request and reply. This allows us to extend any given IWPM message by adding new attributes for just that message. These new enums are created, though, in a way to avoid breaking ABI version 3.
