5:25 a.m.
From: "Daniel P. Berrange" <berrange(a)redhat.com>
The pattern
GError **error;
....
*err = gvir_error_new(...)
is dangerous because 'err' could be NULL, and it is tedious
to expect everyone to check. Introduce a new set of APIs
for setting errors
gvir_set_error(err, ...)
and convert all callers to this new pattern
