cleanups; dark blocks prevented in bframes; warning: bframes have lower quality due to thresholding: decrease quantizer (150/0 for example);
/**************************************************************************
 *
 *  Modifications:
 *
 *  29.03.2002 removed MBFieldToFrame - no longer used (transfers instead)
 *  26.03.2002 interlacing support
 *  02.12.2001 motion estimation/compensation split
 *  16.11.2001 const/uint32_t changes to MBMotionEstComp()
 *  26.08.2001 added inter4v_mode parameter to MBMotionEstComp()
