The input base, |a|, isn't reduced mod |m| in the RSAZ case so
incorrect results are given for out-of-range |a| when the RSAZ
implementation is used. On the other hand, the RSAZ implementation is
more correct as far as constant-time operation w.r.t. |a| is concerned.

$1<<32>>32 worked fine with either 32- or 64-bit perl for a good while,
relying on quirk that [pure] 32-bit perl performed it as $1<<0>>0. But
this apparently changed in some version past minimally required 5.10,
and operation result became 0. Yet, it went unnoticed for another while,
because most perl package providers configure their packages with
-Duse64bitint option.

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,

seems x was a typo for tmp1. It dates to before upstream's

garbage if its input was not square. Now it emits BN_R_NOT_A_SQUARE.
Upstream's 48fe4d6233ac2d60745742a27f820dd88bc6689d then mapped
BN_R_NOT_A_SQUARE to EC_R_INVALID_COMPRESSED_POINT.

Upstream's test vector only compares a*b against b*a. The expected

The same error in https://crbug.com/368351 implies we're actually
causing the compiler to make some assumptions it shouldn't make. The
obvious fix of marking things as visible causes crashes when built with
ASan (ASan's malloc interceptors and ours are conflicting somehow).
Revert this for now. We should study how ASan's interceptors work and
figure out how to make these two coexist.

This clears the last of Android's build warnings from BoringSSL. These
pragmas aren't actually no-ops, but it just means that MinGW consumers
(i.e. just Android) need to explicitly list the dependency (which they
do).
There may be something to be said for removing those and having everyone

consumer's build files. Probably not worth the trouble.

This finally removes the last Android hack. Both Chromium and Android
end up needing this thing (Chromium needs it for WebCrypto but currently
uses the EVP_AEAD version and Android needs it by way of
wpa_supplicant).
On the Android side, the alternative is we finish upstream's
NEED_INTERNAL_AES_WRAP patch, but then it just uses its own key-wrap
implementation. This seems a little silly, considering we have a version
of key-wrap under a different API anyway.
It also doesn't make much sense to leave the EVP_AEAD API around if we
don't want people to use it and Chromium's the only consumer. Remove it
and I'll switch Chromium to the new---er, old--- APIs next roll.

We'd previously been assuming we'd want to predict P-256 and X25519 but,
on reflection, that's nonsense. Although, today, P-256 is widespread and
X25519 is less so, that's not the right question to ask. Those servers
are all 1.2.
The right question is whether we believe enough servers will get to TLS
1.3 before X25519 to justify wasting 64 bytes on all other connections.
Given that OpenSSL has already shipped X25519 and Microsoft was doing
interop testing on X25519 around when we were shipping it, I think the
answer is no.
Moreover, if we are wrong, it will be easier to go from predicting one
group to two rather than the inverse (provided we send a fake one with
GREASE). I anticipate prediction-miss HelloRetryRequest logic across the
TLS/TCP ecosystem will be largely untested (no one wants to pay an RTT),
so taking a group out of the predicted set will likely be a risky
operation.
Only predicting one group also makes things a bit simpler. I haven't
done this here, but we'll be able to fold the 1.2 and 1.3 ecdh_ctx's
together, even.
