* Makefile.am testifaceinit.c: Add a detailed test case
for interface initialization, testing the ability to
add interfaces during class initialization and the ordering
of interface base_init, class init, and interface_init.
(Expected to fail at the moment.)

|
|
* - TestIface1 is added before the class is initialized
|
|
* - TestIface2 is added in base_object_baes_init()

* - TestIface4 is added in test_object_class_init()
|

* - TestIface5 is added in test_object_test_iface1_init()
|
|
* - TestIface6 is added after the class is initialized
