    Reduce memory footprint for CLPF decoding. · e8224c7a

    Instead of having CLPF write to an entire new frame and
    copy the result back into the original frame, make the
    filter able to work in-place by keeping a buffer of size
    frame_width*filter_block_size and delay the write-back
    by one filter_block_size row.
    This reduces the cycles spent in the filter to ~75%.
