Critical regression. Hash lookup was crashing on some platforms
due to negative hashing values being reduced modulo table size
to a negative array index.
* hash.c (equal_hash, eql_hash): Ensure
that value returned is in the range [0,NUM_MAX].
(hash_obj): Unused function removed.
(cobj_hash_op): Use hashing similar to eql hash for
other kinds of references.
(hash_eql, hash_equal): Removed bogus % NUM_MAX reduction.
* hash.h (hash_obj): Declaration removed.
