Log Message:
-----------
Implement AES-GCM-SIV (RFC8452)
Fixes #16721
This uses AES-ECB to create a counter mode AES-CTR32 (32bit counter, I could
not get AES-CTR to work as-is), and GHASH to implement POLYVAL. Optimally,
there would be separate polyval assembly implementation(s), but the only one
I could find (and it was SSE2 x86_64 code) was not Apache 2.0 licensed.
This implementation lives only in the default provider; there is no legacy
implementation.
The code offered in #16721 is not used; that implementation sits on top of
OpenSSL, this one is embedded inside OpenSSL.
Full test vectors from RFC8452 are included, except the 0 length plaintext;
that is not supported; and I'm not sure it's worthwhile to do so.
