Having it in base.h pollutes the global namespace a bit and, in
particular, causes clang to give unhelpful suggestions in consuming
projects.

We would set it to block_size rather than zero. This doesn't cause
problems (the code behaves correctly with either value), but it is a
tiny missed optimization.

Fixes failed compile with [-Werror=implicit-fallthrough=], which is
default on gcc-7.x on distributions like fedora.
Enabling no implicit fallthrough for more than just clang as well to
catch this going forward.

Windows provides _aligned_malloc, so we could provide an
|OPENSSL_aligned_malloc| in the future. However, since we're still
trying to get the zeroisation change landed everywhere, a self-contained
change seems easier until that has settled down.

Allocations by |OPENSSL_malloc| are prefixed with their length.
|OPENSSL_free| zeros the allocation before calling free(), eliminating
the need for a separate call to |OPENSSL_cleanse| for sensitive data.
This change will be followed up by the cleanup in
https://boringssl-review.googlesource.com/c/boringssl/+/19824.

The memcpy of a pointer looks like a typo, though it isn't. Instead,
transcribe what the functions expect into a union and let C fill it in.

This change updates the ChaCha20-Poly1305 AEAD to be able to process
|extra_in| data. It does this by encrypting the extra data byte-by-byte
(because extra data should be very small). Both the generic and assembly
code is updated to be able to include this extra ciphertext in the
Poly1305 calculation.

This tag doesn't actually do anything, except cause UBSan to point out
that malloc doesn't align that tightly. malloc does, however, appear to
align up to 16-bytes, which is the actual alignment requirement of that
code. So just replace 64 with 16.
When we're juggling less things, it'd be nice to see what toolchain
support for the various aligned allocators looks like. Or maybe someday
we can use C++ new which one hopes is smart enough to deal with all
this.

In order to use AES-GCM-SIV in the open-source QUIC boxer, it needs to
be moved out from OPENSSL_SMALL. (Hopefully the linker can still discard
it in the vast majority of cases.)
Additionally, the input to the key schedule function comes from outside
and may not be aligned, thus we need to use unaligned instructions to
read it.

It shouldn't have been defined for variable-length nonces at all, but so
it goes. EVP_CIPHER rejected this by way of EVP_CTRL_GCM_SET_IVLEN
comparing <= 0, but the EVP_AEAD API did not.
I've done the test in a separate file on the assumption that aead_test
will become GTest shortly, at which point it will be easy to stick extra
tests into the same file as the FileTest ones.
Thanks to Daniel Bleichenbacher and Thanh Bui of Project Wycheproof for
the report.

AES-GCM-SIV specifies that the counter is a 32-bit, unsigned number.
These test vectors are crafted to trigger a wrap-around and ensure that
