Adapt to new controls (subsampling). For encoding, the destination format now needs to be set to V4L2_PIX_FMT_JPEG and the subsampling (4:2:2 or 4:2:0) needs to be set using the respective control (V4L2_CID_JPEG_CHROMA_SUBSAMPLING). Required buffer size for destination image during encoding is no longer deduced from the format (which generally implied overestimation), but needs to be given from userspace in sizeimage. Not strictly related to the added controls, this patch also fixes setting the subsampling of the destination image for decoding, depending on the destination format.
