Return an unsigned integer hash value corresponding to the specified `key`. Note that the return value is seemingly random (i.e., the hash is good) but identical on all platforms (irrespective of endianness). Both functions `hash1` and `hash2` return a hash, but both hashes can be assumed to be independent (i.e., there are no known correlations between the results of both hash functions given the same input data).
