Subject: * ext/openssl/ossl.c/.h: Added ossl_x509_name_sk2ary. *
 ext/openssl/ossl.c: Replaced ossl_x509_ary2k by generic macro to   simplify
 future conversions. * ext/openssl/ossl_ssl.c: Implement SSLSocket#client_ca.
 * test/openssl/test_ssl.rb: Add test for SSLSocket#client_ca.   Thanks to
 Ippei Obayashi for providing the patch!   [ Ruby 1.9 - Feature #4481 ]
 [ruby-core:35461]
