- Fix random crashes caused by invalid 32-bit shifts on 32-bit values. - Mark tables as static constants. - Change output normalisation factor from 3/2 to sqrt(2). - Sanity check for subframes and prim_channels to avoid crashes with invalid streams. - Avoid crashing with invalid frames setting a bitalloc_huffman component to 7. While here, tweak COMMENT and remove USE_GROFF. from Brad
