qobject: qobject_from_jsonv() is dangerous, hide it away
qobject_from_jsonv() takes ownership of %p arguments. On failure, we
can't generally know whether we failed before or after %p, so
ownership becomes indeterminate. To avoid leaks, callers passing %p
must terminate on error, e.g. by passing &error_abort. Trap for the
unwary; document and give the function internal linkage.
