 There are several occurences in rendservice.c and rendclient.c of service
 IDs produced by hashing public keys.  They should be properly zeroed when
 functions return/heap is freed.

  * rendclient.c:
    * lookup_last_hid_serv_request() (line 430)
    * directory_get_from_hs_dir() (line 539)
  * rendservice.c:
    * rend_service_intro_has_opened() (line 1562)
    * rend_service_intro_established() (line 1680)
    * rend_service_rendezvous_has_opened() (line 1721)
    * upload_service_descriptor() (line 1981)
    * rend_service_set_connection_addr_port() (line 2463)
