df447ba3a9 Add generic AES-GCM-SIV support.
AES-GCM-SIV is an AEAD with nonce-misuse resistance. It can reuse
hardware support for AES-GCM and thus encrypt at ~66% the speed, and
decrypt at 100% the speed, of AES-GCM.

See https://tools.ietf.org/html/draft-irtf-cfrg-gcmsiv-02

This implementation is generic, not optimised, and reuses existing AES
and GHASH support as much as possible. It is guarded by !OPENSSL_SMALL,
at least for now.
