When a function returns a null pointer on error and only on error, you
can do
if (!foo(foos, errp)) {
... handle error ...
}
instead of the more cumbersome
Error *err = NULL;
if (!foo(foos, &err)) {
error_propagate(errp, err);
... handle error ...
}
A StringProperty's getter, however, may return null on success! We
then fail to call visit_type_str().
Screwed up in 6a146eb, v1.1.
Fails tests/qom-test in my current, heavily hacked QAPI branch. No
reproducer for master known (but I didn't look hard).
