TLS and DTLS share the same code for decryption of AEAD ciphers.
Add tests for all possible AEAD cipher modes (GCM, CCM, CCM_8).
PSK is used to reduce the handshake size (removing certificates).
The decryption suite passes these tests on:
* Libgcrypt 1.6.5 (Ubuntu 14.04)
* Libgcrypt 1.7.6 (Arch Linux)
* Libgcrypt 1.4.5 (CentOS 6). Note that the GnuTLS packages are too old,
so tests that depend on RSA keys fail here (but the new tests pass).
