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 ADR
(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.
