Fair enough.  It seems like it would be more accurate to say that
index.h supports a fixed-size key per table, but different tables can
have keys of different sizes.

By the way, if that's the case, the keys should be void *, and not u8 *,
since the former implies more strongly that they're opaque.  The
key_length should probably be size_t, too.
