e.g. <opencv2/core/core.hpp> become <opencv2/core.hpp> Also renamed <opencv2/core/opengl_interop.hpp> to <opencv2/core/opengl.hpp>
removed void integral(const GpuMat& src, GpuMat& sum, GpuMat& sqsum, Stream& stream) - it fails with NPP_NOT_IMPLEMENTED error updated docs, accuracy and performance tests
