When encoding yuva420 (alpha) frames, the vpx encoder uses a second vpx_codec_ctx to encode the alpha stream. However, codec options were only being applied to the primary encoder. This patch updates codecctl_int and codecctl_intp to also apply codec options to the alpha codec context when encoding frames with alpha. This is necessary to take advantage of libvpx speed optimization options such as 'row-mt', 'cpu-used', and 'deadline' when encoding videos with alpha. Without this patch, the speed optimizations are only applied to the primary stream encoding, and the overall encoding is just as slow as it would be without the options specified.
