A fuzzer run caused the operands of this multiplication to be 512 and
5000000, resulting in a product about 20% too large for int32_t. So
change this from a 16x32->32 to a 16x32->64 multiplication. Since we
right shift by 2 at the end, the end result will still fit in int32_t.
I also had to fix a few follow-on add/sub overflows found by the same
fuzzer input once the multiplication was fixed. I chose to saturate
these, since it wasn't just an intermediate value that overflowed.

This makes a few things a lot clearer when looking at perf trace data:
* What module instances (where they were created) are called
* On what thread
* How frequently
* For how long
ProcessThread will be replaced by TaskQueue moving forward and this is a step towards understanding the behavior of the affected code.

This CL fixes two issues. The first is a tsan complaint about a data
race. The test had a fix to make it deterministic but the race still
existed, so this adds locks around the critical section to appease
the sanitizer.
The second, more annoying issue, is that occasionally the test would
start before the encoder had been configured, as this happens
asynchronously on a task queue. This would cause frames to be queued
up and dropped, but not where we expected them to be dropped.
This was causing some tests to fail very occasionally. I've added
a synchronisation mechanism by posting a barrier task on the queue
and not proceeding with the tests until it finishes.

DXGI capturer highly depends on video adapter and its driver, as well as Windows
itself. I recently found it cannot work on my virtualbox instance any more,
which indicates it may not work well on some specific systems. What worse is,
the APIs do not return a failure in such case.
So this change adds a BlankDetectorDesktopCapturerWrapper, which samples several
pixels in the frame returned by a DesktopCapturer implementation. If all the
pixels selected are blank, this wrapper returns a failure. A typical usage is to
combine BlankDetectorDesktopCapturerWrapper with FallbackDesktopCapturerWrapper,
and use GDI capturer in case of failure.
Usually less than 500 pixels are checked, so the
BlankDetectorDesktopCapturerWrapper should not impact the capturer performance.

It seems to me that we're currently just picking the first CN codec, rather than the one that matches the clock rate of the voice codec. The only test I've gotten to fail by changing this behavior is the one that's also changed in this CL, which explicitly expects a CN codec to be chosen even though there's none matching.
