Fix a race condition with QtDBus blocking for replies.
If an auxiliary thread tried to block on waiting for a reply, and at
the same time the main thread handled the reply, there's room for a
race condition. So ensure only one thread is stopped at
dbus_pending_call_block().
The other thread(s) will be waiting on the QWaitCondition.
It's not a race condition for the main thread to process (and finish
processing) the reply while the auxiliary thread hasn't even started
to wait. The code will ensure that the reply is properly seen.
