    1. Added a bit in frame header to  to indicate if a frame is encoded
    in lossless mode, so decoder does not make the decision based on Q0
    2. Minor changes to make sure that lossy coding works same as when
    the lossless experiment is not enabled.
    3. Renamed function pointers for transforms to be consistent, using
    prefix fwd_txm and inv_txm for forward and inverse respectively
    To encode in lossless mode, using "--lossless=1 --min-q=0 --max-q=0"
    with vpxenc.
