28 * Pack a parser token into 7 bits.
30 * Bison normally numbers user-defined tokens sequentially starting from 258.
31 * If api.token,raw is used, then the numbering starts from 3. As we have
32 * about 50 tokens, the latter case will fit in 7 bits easily; in the former
33 * case the upper bits are constant so we don't need to store them.

38 * Expand a packed token to its original value.
