Add SSL_CTX_get_ciphers()

[rhenium]

There are both set/get functions for SSL:

int SSL_set_cipher_list(SSL *s, const char *str);
STACK_OF(SSL_CIPHER) *SSL_get_ciphers(const SSL *s);

But for SSL_CTX, there is only set function:

int SSL_CTX_set_cipher_list(SSL_CTX *ctx, const char *str);

and currently no get function:

STACK_OF(SSL_CIPHER) *SSL_CTX_get_ciphers(const SSL_CTX *ctx);

Since libssl was made opaque, there is no way for users to access SSL_CTX.cipher_list, so I think it should be implemented.

@mattcaswell can you plus-one? This is a nice complete patch that adds missing opaque-required accessors.
