fa1749dd34 vp9: split superframes in the filtering stage before actual decoding
Significantly increases the efficiency of frame threading, since
individual frames in a superframe can now be decoded in parallel.

This will be needed for frame threading.

bc6e0b64a9 vp9: split last/cur_frame from the reference buffers.
We need more information from last/cur_frame than from reference
buffers, so we can use a simplified structure for reference buffers,
and then store mvs and segmentation map information in last/cur.

This prepares the decoder for frame threading support.

38f99017e6 vp9: Return the correct size when decoding a superframe
According to avcodec.h, avcodec_decode_video2 should return the number of
bytes used if a frame was decoded.

The current implementation returns size - used size of all the subframes.
This fixes the VLC's bug https://trac.videolan.org/vlc/ticket/16836.

The superframe is always fully consumed.

50866c8d95 vp9: fix bugs in updating coef probabilities with parallelmode=1
- The memcpy was completely wrong because
s->prob_ctx[s->framectxid].coef is a [4][2][2][6][6][3] array, whereas
s->prob.coef is a [4][2][2][6][6][11] array.
- The additional check was committed to ffmpeg by Ronald S. Bultje.
