* test/openssl/utils.rb (OpenSSL::TestUtils): ignore out-of-date
OpenSSL before 1.0.

String#succ because it can make modified (wrong) auth_tag longer
than 16 bytes. The longer auth_tag makes that
EVP_CIPHER_CTX_ctrl (and internally aes_gcm_ctrl) fail.
[ruby-core:55143] [Bug #8439] reported by Vit Ondruch.

with Associated Data (AEAD) for OpenSSL versions that support the
GCM encryption mode. It's the only mode supported for now by OpenSSL
itself. Add Cipher#authenticated? to detect whether a chosen mode
does support Authenticated Encryption.
* test/openssl/test_cipher.rb: add tests for Authenticated Encryption.
[Feature #6980] [ruby-core:47426] Thank you, Stephen Touset for
providing a patch!

On NetBSD, if it uses patented algorithms without explicit option,
openssl will abort.

SEGV from AES encryption/decryption. Processing data by
Cipher#update without initializing key (meaningless usage of Cipher
object since we don't offer a way to export a key) could cause SEGV.
In OpenSSL, the EVP which has EVP_CIPH_RAND_KEY flag (such as DES3)
allows uninitialized key, but other EVPs (such as AES) does not
allow it. Calling EVP_CipherUpdate() without initializing key causes
SEGV so we set the data filled with "\0" as the key by default. See
#2768.
* test/openssl/test_cipher.rb: test it.
