Make vivid aware of the difference of planes and buffers. Note that
this does not yet add support for hor/vert downsampled formats.

The successive TOP/BOTTOM fields did not move as they should: only
every other field actually changed position.
The cause was that the tpg needs to know if it is dealing with a
FIELD_ALTERNATE case since that requires slightly different handling.
So tell the TPG whether or not the field setting is for the ALTERNATE
case or not.

The plane size check was hardcoded to plane 0 instead of using the plane
index.
This failed when using the NV61M format which has a larger plane size for
the second plane compared to the first plane.

If the vivid driver is loaded in multiplanar mode, then the capture overlay
functionality should be disabled. This wasn't fully done, which led to
v4l2-compliance errors.

Add AdobeRGB and BT.2020 support.
The colorspace control now orders the colorspaces according to how often
they are used. So rarely used colorspaces are moved to the end. This makes
it more logical when testing colorspace support.

This is useful to test teletext capture applications like alevt and mtt.
It also fixes a previously undetected bug where the PAL VBI start line
of the second field was off by one. Using the new field start defines
helps a lot fixing such bugs.

This adds the ioctl and vb2 queue support for video capture and output.
Part of this is common to both, so that is placed in a vid-common source.
