Comment (by nickm):

 I've had a partial success here.

 My branch `bug25353_032` replaces the `TLSv1_1_method()` check with a
 `SSL_CIPHER_get_id()` test.  (You can see my public repository at
 https://gitweb.torproject.org/nickm/tor.git .)

 The problem here, though, is that this change is not enough to make Tor
 compile when OpenSSL is built with no-deprecated.  Tor uses the following
 deprecated functions:
 {{{
 CRYPTO_cleanup_all_ex_data
 ENGINE_cleanup
 ERR_free_strings
 ERR_load_crypto_strings
 EVP_CIPHER_CTX_cleanup
 EVP_cleanup
 OpenSSL_add_all_algorithms
 SSL_library_init
 SSL_load_error_strings
 X509_get_notAfter
 X509_get_notBefore
 }}}

 The number of functions here makes me think that we should postpone
 compatibility with `no-deprecated` OpenSSL until 0.3.4.  What do you
 think?
