Native child windows on Symbian can cause composition artifacts on S^3
because they own a visible RWindow instance, but the RWindow
technically has no content because child windows paint their content to
their parent's backing store. In the event that a native child widget
completely obscures a top level, the composition engine does not
understand that the child is "empty" and should clear the UI surface
to let the top level "shine through". The result is that articacts can
remain on the UI surface after a transition from a WSERV drawing app to
a Qt (EGL rendering) app.
To fix this issue, we call CWindowGc::Clear() when the native child
widget receives an "expose" event. This clears the UI surface content
and ensures the top level is visible even though it is technically
below another RWindow.

If we're unable to read the first frame, we shouldn't return an end

indefinitely when the playCounter is set to -1 (infinite).

Further observation shows that spin times slightly over the average wait time
produce the best results. This change keeps a heavily weighted average
of the wait times under 1.5ms (1.5 times the max spin threshold), and adjusts
the spin time to be 150% of the average wait time.
Introduce spin time adjustments when spin locking works, and adjust to
between 150% of the average wait time and the maximum threshold.

The maximum spin time threshold is now 1000000ns, or 1ms. Spinning for longer

Change the adaptive spinning code to be elapsed time based instead of
iteration based. The new approach will quickly reduce the amount of
allowed spinning time when it detects that lock contention is resolved
by waiting instead of spinning. We get better results by dynamically
adjusting for elapsed running time instead of trying to fine tune
iteration counts that won't work for all CPU types, speeds, etc.
From observation, lock performance suffers if the spin time is higher
than the minimum wait time. Because of this, QMutex never increases the
spin time, it only reduces the spin time to the minimum observed wait time.
For very long wait times, we disable spinning completely (and always resolve
contention by waiting).
Use QThread::yieldCurrentThread() when spinning on a contended mutex. Comment
from the code: be a good citizen... yielding lets something else run if
there is something to run, but may also relieve memory pressure if not.

Use futex(2) to implement QMutexPrivate::wait() and ::wakeup(). This
makes QMutex perform more or less identically the same as
pthread_mutex_t when contended.
We have to use the contender count in a different way due to the way
that futex() waiting works. Waiting on a futex atomically checks that
the value has not changed from the expected value and then puts the
thread to sleep. So, on Linux, the contender QAtomicInt will only ever
be one of three values: 0 for unlocked, 1 for locked, 2 for contended.
This does mean that there is a slight chance for unfairness due to the
fetch-and-store to zero in the wakeUp() function, but unfortunately this
cannot be avoid as the code is now.

Allow sub-millisecond resolution on systems where it is possible. On UNIX,
with monotonic clock support we get full nanosecond resolution, microsecond
otherwise. On Windows we convert the performance counters to nanoseconds if
availble, otherwise we only have millisecond resolution. On Mac, the mach time
is converted to nanoseconds. On Symbian, we have microsecond resolution.
