Apologies, I've shortcutted the testing by running on MI tests, since "obviously" that
was a MI-only change.

commit 1160d59db83b2a172c980bb7fa5c9dc9961d1b18
Author: Vladimir Prus <vladimir@codesourcery.com>

    Unbreak observer tests.
    
    	gdb/
    	* observer.c (observer_test_first_notification_function)
    	(observer_test_second_notification_function)
    	(observer_test_third_notification_function): Adjust prototype.
    
    	gdb/doc/
    	* observer.texi (test_notification): New observer.
    
    	gdb/testsuite/
    	* gdb.gdb/observer.exp: Use test_notification observer, not
    	normal_stop, everywhere.
    	(test_normal_stop_notifications): Rename to...
    	(test_notifications): ...this.
    	(test_observer_normal_stop): Rename to...
    	(test_observer): ...this.
