    1. Added row-based loopfilter in encoder;
    2. Moved common multi-threaded loopfilter functions from decoder
       to common;
    3. Merged multi-threaded loopfilter code, and made encoder/
       decoder call same function to reduce code duplication.
    
    Encoder tests showed that 1% - 2% speedup was seen for good-quality
    2-pass mode(at speed 3); 1% - 3% speedup using 2 threads and 4% - 6%
    speedup using 4 threads were seen for real-time mode(at speed 7).
