V4L/DVB (5289): Add support for video output overlays.
Add V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY support. Also add support for local and global alpha overlays. Add new field enums V4L2_FIELD_INTERLACED_TB and V4L2_FIELD_INTERLACED_BT. These changes are needed to support the ivtv On Screen Display features. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
