mmdevapi/tests/render.c diff against wine-1.3.27

The rendering tests are now getting close to what I want for submission,
except that
- "exclusive mode disabled" has not been sufficiently tested;
- WINETEST_DEBUG>1 causes GetPosition errors because the tests are so strict
that sleep() is too unprecise.  I need to use the PerfCounter to compute the
position based on elapsed time instead of what I feed to sleep().

It passes on testbot and some native machines at normal debug settings, but
will cause
so many different todo_wine/"succeeded in todo_wine" errors in Wine depending
on which of the 3 drivers is used and whether or not pulseaudio is used with
ALSA that I don't know how to submit the tests prior to fixing more issues with
the wine drivers.
Using WINETEST_DEBUG is already a key to segregating tests that fail in Wine.
