[PULL,09/15] qmp-output-visitor: Favor new visit_free() function

Commit Message

Markus Armbruster July 6, 2016, 9:14 a.m. UTC

From: Eric Blake <[e-mail]>

Now that we have a polymorphic visit_free(), we no longer need
qmp_output_visitor_cleanup(); however, we still need to
expose the subtype for qmp_output_get_qobject().
