mpegtsdemux: Don't pretend doing NAL alignment
Per specification in 2.14.2 "For PES packetization, no specific data
alignment constraints apply". So we should not advertise NAL
alignment.
This bug was introduced at the same moment the alignment field was introduced
10 years ago. The plan was that alignment=none (or no alignment field) was to
be used for mpegtsdemux, but no one noticed the error. The reason is that at
the same moment, everything dealing with H264 started defaulting to AU
alignment.
https://bugzilla.gnome.org/show_bug.cgi?id=606662#c22
This patch will have a side effect that a parser is now needed after the
tsdemux element. The following pipeline will not negotiate anymore as the
mpegtsmux element requires alignment={nal,au}.
... ! tsdemux ! mpegtsmux ! ...

This implements driver stride support but only for single allocation buffers.

v4l2h264dec: Copy frames when GstVideoMeta is not supported
In some case, when downstream does not support GstVideoMeta, we need to
normalize the stride and offset of the buffer so that downstream can render
properly with a GstVideoMeta. This code is not called when GstVideoMeta is
supported downstream.

v4l2codec: Add initial GstVideoMeta support
In this patch we strictly set the GstVideoMeta width/height to the coded width
and height. Further patches will add stride support and frame copying when
downstream does not support GstVideoMeta.
