Fix: libs, tools: Add -list to certain formatted output message names.
    
    Basically, if the message creates its own list, the name should end in
    -list.  This is a hint to the caller that they do not need to add an
    extra layer of lists.  I've further changed the names of these messages
    to be a little shorter, too.
    
    Note that some messages (the resource variants most obviously) create
    their own list but don't have -list in the name.  Here, the list is more
    for organizational purposes rather than indicating that it contains
    items.
