ea5de0d757 videoaggregator: Switch to a GstVideoAggregatorConvertPad subclass
This moves all the conversion related code to a single place, allows
less code-duplication inside compositor and makes the glmixer code less
awkward. It's also the same pattern as used by GstAudioAggregator.

83192bce84 videoaggregator: Move aggregated_frame and the pad buffer into the private struct
The aggregated_frame is now called prepared_frame and passed to the
prepare_frame and cleanup_frame virtual methods directly. For the
currently queued buffer there is a method on the video aggregator pad
now.

cbb4bdbb94 dssim: Add a dssim-error-threshold property
If that threshold is reached, `iqa` will emit an ERROR message on the
bus, stopping any processing.

This way we can do a simpler comparison with gst-validate and the
process will error out if the specified threshold is reached.

087d9bc376 Adds a new Image Quality Assessment plugin.
It only offers one metric for now, "dssim", available if
https://github.com/pornel/dssim was installed on the system
at the time the plugin was compiled.

The spearman correlation for dssim against the TID2008 dataset
is 0.81, against 0.70 for the old ssim implementation, and
it runs 15 times faster.
