This reverts commit 09feb0f3d9.

(In order to make WebRTC happy this also needs to be reverted.)

We currently have the situation where the |tool| and |bssl_shim| code
includes scoped_types.h from crypto/test and ssl/test. That's weird and
shouldn't happen. Also, our C++ consumers might quite like to have
access to the scoped types.

Thus this change moves some of the template code to base.h and puts it
all in a |bssl| namespace to prepare for scattering these types into
their respective headers. In order that all the existing test code be
able to access these types, it's all moved into the same namespace.

OpenSSL upstream's SIMD assembly is rather complex. This pattern of update
calls should be sufficient to stress all the codepaths.

MSVC doesn't have stdalign.h and so doesn't support |alignas| in C
code. Define |alignas(x)| as a synonym for |__decltype(align(x))|
instead for it.

This also fixes -Wcast-qual warnings in rsaz_exp.c.

Chromium's toolchains may now assume C++11 library support, so we may freely
use C++11 features. (Chromium's still in the process of deciding what to allow,
but we use Google's style guide directly, toolchain limitations aside.)

RFC 7359 includes tests for various edge cases. Also, as
CRYPTO_poly1305_update can be used single-shot and streaming, we should
explicitly stress both.
