    The call of MFXVideoENCODE_EncodeFrameAsync may not generate output and
    the function returns MFX_ERR_MORE_DATA with NULL sync point, the input
    frame is cached in this case, so it is possible that all allocated
    frames go into the surfaces_used list after calling
    MFXVideoENCODE_EncodeFrameAsync a few times, then the encoder will fail
    to get an available surface before releasing used frames
    This patch adds a new field of num_extra_frames to GstMsdkEnc and allows
    encode element requires extra frames, the default value is 0.
    This patch is the preparation for msdkvp9enc element.
