Semi-abstract description of an interface. Each service GInterface that
has properties must have one of these attached to it via
tp_svc_interface_set_dbus_properties_info() in its base_init function;
service GInterfaces that do not have properties may have one of these
with no properties.
This structure must either be statically allocated, or duplicated and never
freed, so it always remains valid.
In addition to the documented members, there are two private pointers
for future expansion, which must always be initialized to %NULL.
