d2b5af56cf Revert scoped_types.h change.
This reverts commits:
8d79ed6740

8d79ed6740

Because WebRTC (at least) includes our headers in an extern "C" block,
which precludes having any C++ in them.

8c3c3135a2 Remove scoped_types.h.
This change scatters the contents of the two scoped_types.h files into
the headers for each of the areas of the code. The types are now in the
|bssl| namespace.

09feb0f3d9 Move C++ helpers into |bssl| namespace.
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.

3cab5572b1 Don't align NEWPOLY_POLY.
The alignas in NEWPOLY_POLY told the compiler that it could assume a
certain alignment. However, values were allocated with malloc with no
specific alignment.

We could try and allocate aligned memory but the alignment doesn't have
a performance impact (on x86-64) so this is the simpler change. (Also,
Windows doesn't have |posix_memalign|. The cloest thing is
_alligned_alloc but then one has to use a special free function.)

3675dddab9 newhope_test: corrupt things harder.
This ensures that the test is not flaky after lots of iterations.

Along the way, change newhope_test.cc to C++.

adf27430ef Be consistent about 𝑥_tests.txt
Some files were named 𝑥_test.txt and some 𝑥_tests.txt. This change
unifies around the latter.

dbec90b623 Sort out signedness issues.
Windows is, not unreasonably, complaining that taking abs() of an unsigned is
ridiculous. But these values actually are signed and fit very easily in an int
anyway.

6b7436b0d2 newhope: restore statistical tests.
One of these tests the distribution of noise polynomials; the other
tests that that agreed-upon keys (prior to whitening) have roughly equal
numbers of 0s and 1s.

Along the way, expose a few more API bits.

27e863e711 newhope: improve test vectors.
This commit adds coverage of the "offer" (first) step, as well as
testing all outputs of the "accept" (second) step, not just the shared
key.

db207264ad newhope: refactor and add test vectors.
The test vectors are taken from the reference implementation, modified
to output the results of its random-number generator, and the results of
key generation prior to SHA3.  This allows the interoperability of the
two implementations to be tested somewhat.

To accomplish the testing, this commit creates a new, lower-level API
that leaves the generation of random numbers and all wire encoding and
decoding up to the caller.

bc57d55c9f Corrupt the newhope secret key directly.
Rather than use an internal function in a test (which would need an
OPENSSL_EXPORT to work in a shared-library build), this change corrupts
the secret key directly.

045a0ffe35 Import `newhope' (post-quantum key exchange).
This derives from the reference implementation:

Source: https://github.com/tpoeppelmann/newhope/tree/master/ref at bc06c1ac
Paper: https://eprint.iacr.org/2015/1092

However, it does not interoperate, due to the replacement of SHAKE-128
with AES-CTR (for polynomial generation) and the replacement of SHA-3
with SHA-256 (for key whitening).
