* ext/openssl/extconf.rb: add check for OBJ_NAME_do_all_sorted.
* ext/openssl/ossl_cipher.c (ossl_s_ciphers): new method OpenSSL::Cipher.ciphers. it returns all the cipher names. * ext/openssl/ossl_cipher.c (ossl_cipher_init): refine warning message. * ext/openssl/lib/openssl/cipher.rb: reimplement without eval() and add constants AES128, AES192, AES256. [ruby-dev:28610] * ext/openssl/lib/openssl/digest.rb: reimplement without eval(). * test/openssl/test_cipher.rb, test_digest: fix about reimplemented features. * sample/openssl/cipher.rb: rewrite all. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@10137 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
