Some UVC video cameras contain metadata in their payload headers. This patch extracts that data, adding more clock synchronisation information, on both bulk and isochronous endpoints and makes it available to the user space on a separate video node, using the V4L2_CAP_META_CAPTURE capability and the V4L2_BUF_TYPE_META_CAPTURE buffer queue type. By default, only the V4L2_META_FMT_UVC pixel format is available from those nodes. However, cameras can be added to the device ID table to additionally specify their own metadata format, in which case that format will also become available from the metadata node.
