72e4a717bd Fix The GNU ToolChain Authors copyright notice
I (and maybe one or two others) added a (C) to the copyright notice
regardless of the contribution checklist[1] not mentioning it.  Fix all
these instances so that the notice reads as "Copyright The GNU Toolchain
Authors" across the source code.

4cc79c2177 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.
