Phantom doesn't run with some OpenSSL cipher suites

[burthen]

Consider we have Phantom config file which contains such a section (with GOST cipher string from man ciphers):

    transport_t ssl_transport = transport_ssl_t {
      auth = NULL
      ciphers = "GOST2001-GOST89-GOST89"
      timeout = 1s
    }

We assume also, that cipher string mentioned above is known by openssl library:

$ openssl ciphers | grep -oP "GOST.+?:"
GOST2001-GOST89-GOST89:
GOST94-GOST89-GOST89:

Then, if we have build Phantom from current state of the public repo, and then check this config, we will recieve such an error:

$ ./phantom check openssl_min.conf 
2016-07-05 11:37:27.070 +0300 [error] [] SSL error:1410D0B9:SSL routines:SSL_CTX_set_cipher_list:no cipher match
2016-07-05 11:37:27.070 +0300 [error] [] SSL_CTX_set_cipher_list

But, if we add including OpenSSL config <openssl/conf.h> and initializing it in pd/ssl/ssl.C, for instance, like this:

$ git diff pd/ssl/ssl.C
diff --git a/pd/ssl/ssl.C b/pd/ssl/ssl.C

and we can run it. :-)
