 Commit 49de5431d53b] made Tor use `SSL_set_app_data` and
 `SSL_get_app_data` instead of its previous hash table to look up the
 `tor_tls_t *` object corresponding to an `SSL *` object.  Unfortunately:

 * The patch left in two hash-table helper functions that it made unused.
 Reported by mobmix.
 * The patch did not check the result of `SSL_set_app_data` for errors.
 Reported by piebeer.
 * The `SSL_*_app_data` functions are actually macros wrapping
 corresponding `SSL_*_ex_data` functions in such a way that a program that
 tries to use the `app_data` and `ex_data` functions at the same time will
 break horribly.
