librt: add test (bug 28213)
This test implements following logic: 1) Create POSIX message queue. Register a notification with mq_notify (using NULL attributes). Then immediately unregister the notification with mq_notify. Helper thread in a vulnerable version of glibc should cause NULL pointer dereference after these steps. 2) Once again, register the same notification. Try to send a dummy message. Test is considered successfulif the dummy message is successfully received by the callback function.
