Use standard integer types for pixel values and coefficients. For coefficients, use int16_t (instead of short); for pixel values in 16-bit intermediates, use uint16_t (instead of unsigned short); for all others, use uint8_t (instead of unsigned char).

changed to use a fixed number for update probabity This commit is to remove two arrays, which contain the probabilities of how likely each probability in coef_probs table is updated. The commit changed to use a fixed number "252". Surprisedly, the overall impact on quality is close to zero, which basically says the two big static arrays are not helpful at all. derf: -0.016%, -0.020% std-hd: 0.000%, -0.013% yt: -0.022%, +0.007% yt-hd: -0.038%, +0.034% Change-Id: Ifee94d28a37dcab4f1d2b994bd5b07575be42b72 2012-05-24 21:02:12 +02:00			`#define COEF_UPDATE_PROB 252`
