Given your comments on vararg naming elsewhere in the series, I'm also
thinking this is a good chance to fix this to be named
qobject_from_vjsonf() (making it obvious it is the va_list form of
formatted json, and similar to printf/vprintf or my
qtest_startf/qtest_vstartf in my v7 preliminary cleanup series).
