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.

This is the first structure to be implemented with the new BIGNUM ASN.1
routines. Object reuse in the legacy d2i/i2d functions is implemented by
releasing whatever was in *out before and setting it to the
newly-allocated object. As with the new d2i_SSL_SESSION, this is a
weaker form of object reuse, but should suffice for reasonable callers.
As ECDSA_SIG is more likely to be parsed alone than as part of another
structure (and using CBB is slightly tedious), add convenient functions
which take byte arrays. For consistency with SSL_SESSION, they are named
to/from_bytes. from_bytes, unlike the CBS variant, rejects trailing
data.
Note this changes some test expectations: BER signatures now push an
error code. That they didn't do this was probably a mistake.

wrec altogether. SSL3_RECORD is now only used to maintain state about

This also removes the outgoing alignment memcpy and simply calls
SSL_AEAD_CTX_seal with the parameters as appropriate. From bssl speed
tests, this seems to be faster on non-ARM and a bit of a wash on ARM.

The downside is that we pay one more copy of the message data in the common

ssl3_get_message's interface to allow the handshake data being in the

The error queue should only take ownership of the data if ERR_get_* is called,
not ERR_peek_*. Add a test for ERR_peek_error_line_data.

This is no longer used but, by retaining it, we might miss cases where

Implementations of ENGINEs often don't want to implement every function.

I misunderstood the OpenSSL semantics here. When receiving an error data
pointer via ERR_get_error_line_data and friends, although the error is
cleared, OpenSSL retains ownership of the data pointer. It's kept in the
cleared error until another error overrides it, or the whole error queue
is cleared.
It's pretty odd to have live pointers in empty errors so this change
allows an error queue to retain one data pointer. Thus the pointer
returned from ERR_get_error_line_data is valid until the next call to
ERR_get_error_line_data, or until the queue is freed.
From reviewing uses of the API, this is sufficient for all of them.

Chromium does not like static initializers, and the CPU logic uses one to
initialize CPU bits. However, the crypto library lacks an explicit
initialization function, which could complicate (no compile-time errors)
porting existing code which uses crypto/, but not ssl/.
Add an explicit CRYPTO_library_init function, but make it a no-op by default.
It only does anything (and is required) if building with
BORINGSSL_NO_STATIC_INITIALIZER.

This is cleaner than the OpenSSL code was, at least, but it's hardly
beautiful due to the "standard" that it's trying to implement. (See
[1].)
The references from the PKCS#8 code to various ciphers have digests have
been made into function pointer references rather than NIDs so that the
linker will be able to drop RC2 code for binaries that don't call PKCS#8
or #12 functions.
A bug that crashed OpenSSL/BoringSSL when parsing a malformed PKCS#8
structure has been fixed too.

Previously, public headers lived next to the respective code and there
were symlinks from include/openssl to them.
This doesn't work on Windows.
This change moves the headers to live in include/openssl. In cases where
some symlinks pointed to the same header, I've added a file that just
includes the intended target. These cases are all for backwards-compat.
