28243c08db Add PSS parameter check.
Avoid seg fault by checking mgf1 parameter is not NULL. This can be
triggered during certificate verification so could be a DoS attack
against a client or a server enabling client authentication.

Thanks to Loïc Jonas Etienne (Qnective AG) for discovering this bug.

CVE-2015-3194

(Imported from upstream's c394a488942387246653833359a5c94b5832674e and test
data from 00456fded43eadd4bb94bf675ae4ea5d158a764f.)

cb852981cd Fix leak with ASN.1 combine.
When parsing a combined structure pass a flag to the decode routine
so on error a pointer to the parent structure is not zeroed as
this will leak any additional components in the parent.

This can leak memory in any application parsing PKCS#7 or CMS structures.

CVE-2015-3195.

Thanks to Adam Langley (Google/BoringSSL) for discovering this bug using
libFuzzer.

PR#4131

(Imported from upstream's cc598f321fbac9c04da5766243ed55d55948637d, with test
from our original report. Verified ASan trips up on the test without the fix.)

ef14b2d86e Remove stl_compat.h.
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.)

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.

0f86965ca0 Rename evp_test to evp_extra_test.
This matches how upstream imported that test. evp_test will be used for
the subset of upstream's evp_test which land in our crypto/evp layer.
(Some of crypto/evp is in crypto/cipher for us, so those tests will be
in a ported cipher_test.)
