OpenCV C++ core and Python cv2 binding: Mat ownership and deallocation across the language boundary

The integration goal is to define clear ownership and release timing for cv::Mat objects that cross from OpenCV C++ core into the Python cv2 binding. The C++ core uses reference-counted cv::Mat with shallow copy semantics. The Python binding wraps a Mat in a capsule with a custom deallocator that decrements the C++ refcount when the Python object is finalize
