* sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.

Also, don't assume VALBITS / RAND_BITS is less than 5,
and don't rely on undefined behavior when shifting a 1 left into
the sign bit.
* lisp.h (get_random): Change signature to match.

         * lread.c (hash_string): Use size_t, not int, for hash computation.
         Normally we prefer signed values; but hashing is special, because
         it's better to use unsigned division on hash table sizes so that
