Add tests for AEAD functions: AES-128-GCM, AES-256-GCM and
ChaCha20+Poly1305.

Add support for Chacha20 + Poly1305.

Switches AES-GCM ciphersuites to use AEAD interfaces.

This change allows AEADs to be used in ssl/ to implement SSL/TLS
ciphersuites.

This change adds an AEAD interface to EVP and an AES-GCM implementation
suitable for use in TLS.

The previous version of the function made adding AEAD changes very
difficult. This change should be a semantic no-op - it should be purely
a cleanup.
