It would be nice to have a gst_tag_list_is_empty(). Currently the only way to
find out whether a tag list is empty is to cast it to a structure and use
gst_structure_n_fields() directly, which is not only unintuitive but also not
really 100% correct since the derivation from GstStructure is not guaranteed or
mentioned anywhere.

Patch to follow.
