This commit adds support for the coding of intensity stereo spectral coefficients. It also fixes the Mid/Side coding of band_types higher than RESERVED_BT (M/S must not be applied to their spectral coefficients, but marking M/S as present in encode_ms_info() is okay). Much of the changes here were taken from the decoder and inverted. This commit does not change the functionality of the decoder as the previous patch in this series zeroes ms_mask and is_mask.
