Philip Withnall 51acb01f73 gobject: Fix strict aliasing warnings with g_set_object() ... When calling `g_set_object()` for a type derived from `GObject`, GCC 9.2 was giving the following strict aliasing warning: ``` ../../source/malcontent/libmalcontent-ui/user-controls.c:1001:21: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] 1001 | if (g_set_object (&self->user, user)) /opt/gnome/install/include/glib-2.0/gobject/gobject.h:744:33: note: in definition of macro ‘g_set_object’ 744 | (g_set_object) ((GObject **) (object_ptr), (GObject *) (new_object)) \ | ^~~~~~~~~~ ``` This was due to the `(GObject **)` cast. Pass the pointer through a union to squash this warning. We already do some size and type checks of the dereferenced type, which should catch casual errors. The `g_object_ref()` and `g_object_unref()` calls which subsequently happen inside the `g_set_object()` function also do some dynamic type checks. Add a test.
