    hash-table: change the hash key() method to a more typical hasher() method that returns hash_t
    
    Eliminate need to duplicate the data being hashed as a key, instead
    have the hasher() function feed it piece meal into a primitive (such as
    was done by hostpair).  Abuse 'typedef struct' so that all code is
    strongly encouraged to use hash_t.hash and, hence, a consistently
    sized hash value.
