libv4l: add support for fixing upside down images to libv4lconvert
From: Hans de Goede <j.w.r.degoede@hhs.nl>
Add support to libv4lconvert to flipping the image for upside down mounted
sensors, libv4lconvert will do this automatically if the webcam sets a
flag in its query_fmt reply indicating that this is necessary, this fixes
the upside down image on Philips SPC200NC images
Priority: normal
Signed-off-by: Hans de Goede <j.w.r.degoede@hhs.nl>
