    This commit implements support for twopass encoding using the xiphrc
    experimental rate control system. Most of the code and logic comes
    from the theora project encoder.
    Currently support is limited to the bitrate targeting mode of the
    rate control system and while it does visibly improve quality and does
    bring rate closer to the target than the one pass mode there's still
    tuning and bug fixing to be done.
