Copies the contents for the given tag into the value, possibly merging
multiple values into one if multiple values are associated with the tag.
Use gst_tag_list_get_string_index (list, tag, 0, value) if you want
to retrieve the first string associated with this tag unmodified.
The resulting string in value will be in UTF-8 encoding and should be
freed by the caller using g_free when no longer needed. The
returned string is also guaranteed to be non-NULL and non-empty.
