Yah, rather than copying qmp_qom_list() I think a proper interface
would've been warranted.

Perhaps an object_link_foreach() that mirrors object_child_foreach()?
For maybe just a more generic object_foreach() with a type mask?

Another approach would be to re-use or genericize qmp_qom_list() but
that seems like extra allocations/cleanup that aren't really
necessary outside of QMP/QAPI return values.
