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).

Moving segmentation struct from MACROBLOCKD to VP9_COMMON. VP9_COMMON is the right place to segmentatation struct because it has global segmentation parameters, not something specific to macroblock processing.
