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).

The bare essentials are now in place to perform decryption
(HKDF-Expand-Label, calculation of traffic secrets, AEAD integration).
Can successfully decrypt the initial handshake message. Only AES ciphers
are supported, ChaCha20-Poly1305 still needs to be added.
Note: "decryption" indeed works, but dissection needs to be updated. The
padding must be stripped and the content type extracted.
