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.

There's a __pragma expression which allows this. Android builds us Windows with
MinGW for some reason, so we actually do have to tolerate non-MSVC-compatible
Windows compilers. (Clang for Windows is much more sensible than MinGW and
intentionally mimicks MSVC.)

MinGW doesn't understand MSVC's pragmas and warns a lot. #pragma warning is
safe to suppress, so wrap those to shush them. This also lets us do away with a
few ifdefs.

That was probably more complexity than we needed. Nothing uses it
anymore, now that getting to the PKCS#8 logic isn't especially tedious.

Many consumers need SPKI support (X.509, TLS, QUIC, WebCrypto), each
with different ways to set signature parameters. SPKIs themselves can
get complex with id-RSASSA-PSS keys which come with various constraints
in the key parameters. This suggests we want a common in-library
representation of an SPKI.

This adds two new functions EVP_parse_public_key and
EVP_marshal_public_key which converts EVP_PKEY to and from SPKI and
implements X509_PUBKEY functions with them. EVP_PKEY seems to have been
intended to be able to express the supported SPKI types with
full-fidelity, so these APIs will continue this.

This means future support for id-RSASSA-PSS would *not* repurpose
EVP_PKEY_RSA. I'm worried about code assuming EVP_PKEY_RSA implies
acting on the RSA* is legal. Instead, it'd add an EVP_PKEY_RSA_PSS and
the data pointer would be some (exposed, so the caller may still check
key size, etc.) RSA_PSS_KEY struct. Internally, the EVP_PKEY_CTX
implementation would enforce the key constraints. If RSA_PSS_KEY would
later need its own API, that code would move there, but that seems
unlikely.

Ideally we'd have a 1:1 correspondence with key OID, although we may
have to fudge things if mistakes happen in standardization. (Whether or
not X.509 reuses id-ecPublicKey for Ed25519, we'll give it a separate
EVP_PKEY type.)

DSA parsing hooks are still implemented, missing parameters and all for
now. This isn't any worse than before.

Decoupling from the giant crypto/obj OID table will be a later task.

This centralizes the conditional logic into openssl/base.h so that it
doesn't have to be repeated. The name |OPENSSL_PRINTF_FORMAT_FUNC| was
chosen in anticipation of eventually defining an
|OPENSSL_PRINTF_FORMAT_ARG| for MSVC-style parameter annotations.

When using CMake to build with MSVC, MSVC complains about unreachable
code in the <xtree> header. This incantation silences that.

This imports the EVP_PKEY test data of upstream's evptests.txt, but
modified to fit our test framework and with a new test driver. The
remainder of the test data will be imported separately into aead_test
and cipher_test.

Some minor changes to the test format were made to account for test
framework differences. One test has different results since we don't
support RSA signatures with omitted (rather than NULL) parameters.
Otherwise, the biggest difference in test format is that the ad-hoc
result strings are replaced with checking ERR_peek_error.

This adds a file-based test framework to crypto/test. It knows how to
parse formats similar to either upstream's evp_test and our aead_test.

hmac_test has been converted to that with tests from upstream's
evp_test. Upstream tests it against the deprecated EVP_PKEY_HMAC API,
which will be tested by running evp_test against the same input file, to
avoid having to duplicate the test vectors. hmac_test runs those same
inputs against the supported HMAC_CTX APIs.
