libv4l: rewrite video processing code
From: Hans de Goede <hdegoede@redhat.com>
Rewrite video processing code to make it easier to add more video filters
(and with little extra processing cost). As part of this the normalize
filter has been removed as it wasn't functioning satisfactory anyways
Priority: normal
Signed-off-by: Hans de Goede <hdegoede@redhat.com>
