Use IPP library to optimize Libjpeg's SW JPEG encoder

Issue: Libjpeg's SW JPEG encoder is used by Camera to compress small pictures, including thumbnail pictures.
It will be great if we optimize it.

Solution: By calling IPP library to do the core encoding processes: IDCT, Quantization and Huffman coding,
the encodingspeed will be increased by 30%.
