ck_hs_set — store key into a hash set

       The  ck_hs_set(3) function will store the key specified by the key argument in the hash set pointed to by
       the hs argument. The key specified by key is expected to have  the  hash  value  specified  by  the  hash
       argument (which was previously generated using the CK_HS_HASH(3) macro).

       If  the  call to ck_hs_set(3) was successful then the key specified by key was successfully stored in the
       hash set pointed to by hs.  If the key already exists in the hash set, then it is replaced by key and the
       previous value is stored into the void pointer pointed to by the previous argument. If previous is set to
       NULL then key was not a replacement for an existing entry in the hash set.

       Behavior is undefined if key or hs are uninitialized. The function will also return false if the hash set
       could not be enlarged to accomodate key insertion.
