Gets the ordered list of values from this.
The list and its contents are owned by this, and must not be freed.
For example, for an <code>ADR</code> (postal address) attribute, this will return the components of the postal address.
This may be called on a single-valued attribute (i.e. one for which is_single_valued returns true) and will return a one-element list in that case. Alternatively, use get_value in such cases.
