commit 9d5ac9532c58c8b2d10d5e8ee8029dcb40aecfbe
Author: Kazuki Yamaguchi <k at rhe.jp>
Date:   Sun Apr 10 13:18:50 2016 +0900

    Add SSL_CTX_get_ciphers()
    
    Add an accessor for SSL_CTX.
    
    Since libssl was made opaque, there is no way for users to access the
    cipher_list, while users can set the cipher_list by
    SSL_CTX_set_cipher_list().

+The details of the ciphers obtained by SSL_get_ciphers(), SSL_CTX_get_ciphers()
 SSL_get1_supported_ciphers() and SSL_get_client_ciphers() can be obtained using
 the L<SSL_CIPHER_get_name(3)> family of functions.
 
 Call SSL_get_cipher_list() with B<priority> starting from 0 to obtain the
 sorted list of available ciphers, until NULL is returned.
 
-Note: SSL_get_ciphers() and SSL_get_client_ciphers() return a pointer

 The stack returned by SSL_get1_supported_ciphers() should be freed using
 sk_SSL_CIPHER_free().
