Vp9 encoder supports several inter-layer prediction modes. This adds
possibility to control and test them in video/ss/sv loopback.
Filtering of sent packets has been modified. In addition to high
spatial and temporal layers it now filters out packets of low spatial
layers where non_ref_for_inter_layer_pred bit is set to true.
