Log:

Fixes a few problems with AutoExpire QThreads porting in [64d51365568348b91e307cab39b6ef73f8c23be6].

Before the QThread porting the threads were shutdown somewhat promptly by use of a signal. This instead uses the already existing QWaitCondition + a new wakeable Sleep() function for the sleeps in both threads.

Note: The porting got rid of the sleep() cancelling signal and replaced it with a QThread::quit(), which tells QThread::exec() to exit; but we never call that, so this is a no-op. Also, the Sleep() function was supposed to exit early after expire_thread_running was cleared; but this check was replaced with an QThread::isRunning() method invocation, which will always return true even after the expire_thread_run variable is cleared. This old Sleep() early exit wouldn't necessarily have worked anyway since expire_thread_running was not declared volatile so the check could have been optimized away.
