When the thread that got woken up by release() is supposed to release()
to wake up another thread, we were deadlocking. This happened because we
cleared the bit indicating that there was contention when the first
release(). Instead of storing a single bit, we now store the number of
threads waiting.

The issue was introduced by eaee1209f0, so
it affected only 5.9.2.
[ChangeLog][QtCore][QSemaphore] Fixed a regression that would make
tryAcquire() not to wait forever if the timeout was a negative
value. Note: new code is advised to only use -1 to indicate "forever",
as some other functions taking timeout periods do not accept other
values.

When one of the QCOMPAREs in Consumer::run() fails, the consumer
returns early, leaving the producer deadlocked in a QSemaphore's
acquire() call. Change these to tryAcquire() with a large timeout,
so the producer, too, eventually leaves run().

This is a simple RAII class that makes semaphore releasing
reliable in the face of exceptions and early returns.
This code originates from KDTools' KDSemaphoreReleaser[1], but
has been extensively reworked to support C++11 move semantics.

The test tries to acquire a semaphore that isn't ready, so it will
timeout. The test is working properly.
The only problem is that 10 ms is too strict. For a wide variety of
reasons, especially since the Qt CI system runs multiple tests in
parallel, the program may not run again in that 10 ms window.

Timers are not entirely precise; if we ask for a timeout of
10000 milliseconds, we might time out in 9999 instead.
Also, we know the expected elapsed time in each case, so do a fuzzy
comparison against that time.
Previously the test was verifying that the elapsed time was greater than
or equal to the timeout in the case where a timeout was expected, which
means the test would not detect bugs which incorrectly caused the
timeout to occur later than it should.
