As per some IRC conversations, at this point I think we need to
duplicate the structures.  In the future we may change to some other
scheme for handling strings but for now this is it.  The lvm_str_list
has been in lvm2app.h for a while now and other functions use it.

Actually doxygen handles this strangely so I'm fixing this as well as a
lot of the other doxygen tags as a result of the documentation updates.
Another patch will be soon coming.


Thanks for the feedback.
