In order to get the intended behaviour of the stateful video
decoder API where only the OUTPUT queue needs to be enabled and fed
buffers in order to get the SOURCE_CHANGED event that configures the
CAPTURE queue, we want the device to run should either queue be
streaming.

Fixes: "staging/bcm2835-codec: Log the number of excess supported formats"
Which used %u for printing a size_t, and 64bit builds then log a warning.

If the format is detected by the driver and a V4L2_EVENT_SOURCE_CHANGE
event is generated, then pass on the pixel aspect ratio as well.

v4l_cropcap calls our vidioc_g_pixelaspect function to get the pixel
aspect ratio, but also calls g_selection for V4L2_SEL_TGT_CROP_BOUNDS
and V4L2_SEL_TGT_CROP_DEFAULT. Whilst it allows for vidioc_g_pixelaspect
not to be implemented, it doesn't allow for either of the other two.

Add in support for the additional selection targets.

Providing the relevant licence has been purchased, then Pi0-3
can decode VC-1.
