This is an attempt to make MSVC happy. Currently it's saying:

f27459e412 Add SPAKE2 over Ed25519.
SPAKE2 is a password-authenticated key exchange. This implementation is
over the twisted Edwards curve Ed25519, and uses SHA-512 as the hash
primitive.

See https://tools.ietf.org/html/draft-irtf-cfrg-spake2-03

4cc36adf5a Make it possible to tell what curve was used on the server.
We don't actually have an API to let you know if the value is legal to
interpret as a curve ID. (This was kind of a poor API. Oh well.) Also add tests
for key_exchange_info. I've intentionally left server-side plain RSA missing
for now because the SSL_PRIVATE_KEY_METHOD abstraction only gives you bytes and
it's probably better to tweak this API instead.

(key_exchange_info also wasn't populated on the server, though due to a
rebasing error, that fix ended up in the parent CL. Oh well.)

77c3c0b025 Enable Ed25519 when building with OPENSSL_SMALL.
OPENSSL_SMALL will still cause the smaller base-point table to be used

d28f59c27b Switch the keylog BIO to a callback.
The keylog BIO is internally synchronized by the SSL_CTX lock, but an
application may wish to log keys from multiple SSL_CTXs. This is in
preparation for switching Chromium to use a separate SSL_CTX per profile
to more naturally split up the session caches.

It will also be useful for routing up SSLKEYLOGFILE in WebRTC. There,
each log line must be converted to an IPC up from the renderer
processes.

This will require changes in Chromium when we roll BoringSSL.

Once QUIC has moved to the “_old” version the unsuffixed name can be

behind a CRYPTO_once and not burden callers.

74f711083d Parse RSAPrivateKey with CBS.
This removes the version field from RSA and instead handles versioning
as part of parsing. (As a bonus, we now correctly limit multi-prime RSA
to version 1 keys.)

Most consumers are also converted. old_rsa_priv_{de,en}code are left
alone for now. Those hooks are passed in parameters which match the old
d2i/i2d pattern (they're only used in d2i_PrivateKey and
i2d_PrivateKey).

Include a test which, among other things, checks that public keys being
serialized as private keys are handled properly.

83a82981dc Rename BIO_print_errors_fp back to ERR_print_errors_fp & refactor it.
A previous change in BoringSSL renamed ERR_print_errors_fp to
BIO_print_errors_fp as part of refactoring the code to improve the
layering of modules within BoringSSL. Rename it back for better
compatibility with code that was using the function under the original
name. Move its definition back to crypto/err using an implementation
that avoids depending on crypto/bio.

45fb1be33e Remove std::unique_ptr dependency on bssl_shim's scoped types.
This is in preparation for using RAII in the unit tests. Those tests are built
in Chromium as well, but Chromium does not have C++11 library support across
all its toolchains. Compiler support is available, so add a partial
reimplementation of std::unique_ptr and std::move under crypto/test/. The
scopers for the crypto/ library are also moved there while the ones for ssl/
stay in ssl/test/.

3e719319be Lowercase some Windows headers.
MinGW on Linux needs lowercase include files. On Windows this doesn't
matter since the filesystems are case-insensitive, but building
BoringSSL on Linux with MinGW has case-sensitive filesystems.

d53b2c3c88 Fix out-of-bounds memory write in speed.cc.
Windows x64 uses the IL32P64 data model, which means that unsigned int
is 32 bits and size_t is 64 bits. Previously, the expression
|~(alignment - 1)| resulted in the 32-bit value 0xFFFFFFF0, which was
then extended to the 64-bit value 0x00000000FFFFFFF0 when promoted to
size_t. When the input pointer was masked with this value, the result
was a pointer that was usually way outside the boundaries of the array.

The new code casts |alignment| to size_t first prior to the bitwise
negation, resulting in the correct mask value of 0xFFFFFFFFFFFFFFF0.

2b2d66d409 Remove string.h from base.h.
Including string.h in base.h causes any file that includes a BoringSSL
header to include string.h. Generally this wouldn't be a problem,
although string.h might slow down the compile if it wasn't otherwise
needed. However, it also causes problems for ipsec-tools in Android
because OpenSSL didn't have this behaviour.

This change removes string.h from base.h and, instead, adds it to each
.c file that requires it.
