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).

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

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.
