Rostislav Pehlivanov 43b378a0d3 aaccoder: move the quantization functions to a separate file This commit moves the quantizer to a separate header file. This allows the quantizer to be used from a separate files outside of aaccoder without having to put another function pointer and will result in a slight speedup as the compiler can do more optimizations. This is required for commits following. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>		9 years ago
