openssl: support non AES-GCM AEAD ciphers in OpenSSL::Cipher
* ext/openssl/ossl_cipher.c (ossl_cipher_get_auth_tag, ossl_cipher_set_auth_tag): Check if the cipher flags retrieved by EVP_CIPHER_CTX_flags() includes EVP_CIPH_FLAG_AEAD_CIPHER to see if the cipher supports AEAD. AES-GCM was the only supported in OpenSSL 1.0.1. (Init_ossl_cipher): Fix doc; OpenSSL::Cipher::AES.new(128, :GCM) can't work. * ext/openssl/openssl_missing.h: Define EVP_CTRL_AEAD_{GET,SET}_TAG if missing. They are added in OpenSSL 1.1.0, and have the same value as EVP_CTRL_GCM_{GET,SET}_TAG and EVP_CTRL_CCM_{GET,SET}_TAG. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@55388 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
