2021-09-22qcam: viewfinder: Pass stride value to viewfinderLaurent Pinchart
qcam currently assumes that no padding is used at end of lines, and uses the image width as the stride. This leads to rendering failures with some formats on some platforms. To prepare for stride support, add a stride parameter to the ViewFinder::setFormat() function to pass the stride from the stream configuration to the viewfinder.

2021-09-07qcam: Use Image class to access pixel dataLaurent Pinchart
Replace the manual implementation of frame buffer mapping with the Image class to improve code sharing. The ViewFinder API is updated to take an Image pointer in the render() function to prepare for multi-planar buffer support.

The MappedBuffer structure is a custom container that binds a data pointer with a length. This is exactly what Span is. Use it instead.
