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

8d79ed6740 Assume that MSVC supports C++11.
MSVC doesn't define __cplusplus as 201103 to indicate C++11 support, so
just assume that the compiler supports C++11 if _MSC_VER is defined.

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

2f6410ba4e Rewrite ECPrivateKey serialization.
Functions which lose object reuse and need auditing:
- d2i_ECParameters
- d2i_ECPrivateKey

This adds a handful of bytestring-based APIs to handle EC key
serialization. Deprecate all the old serialization APIs. Notes:

- An EC_KEY has additional state that controls its encoding, enc_flags
  and conv_form. conv_form is left alone, but enc_flags in the new API
  is an explicit parameter.

- d2i_ECPrivateKey interpreted its T** argument unlike nearly every
  other d2i function. This is an explicit EC_GROUP parameter in the new
  function.

- The new specified curve code is much stricter and should parse enough
  to uniquely identify the curve.

- I've not bothered with a new version of i2d_ECParameters. It just
  writes an OID. This may change later when decoupling from the giant
  OID table.

- Likewise, I've not bothered with new APIs for the public key since the
  EC_POINT APIs should suffice.

- Previously, d2i_ECPrivateKey would not call EC_KEY_check_key and it
  was possible for the imported public and private key to mismatch. It
  now calls it.

62882187c9 Update comments to better document in-place semantics.
(Comment-only change; no functional difference.)

Some code was broken by the |d2i_ECDSA_SIG| change in 87897a8c. It was
passing in a pointer to an existing |ECDSA_SIG| as the first argument
and then simply assuming that the structure would be updated in place.
The comments on the function suggested that this was reasonable.

This change updates the comments that use similar wording to either note
that the function will never update in-place, or else to note that
depending on that is a bad idea for the future.

I've also audited all the uses of these functions that I can find and,
in addition to the one case with |d2i_ECDSA_SIG|, there are several
users of |d2i_PrivateKey| that could become a problem in the future.
I'll try to fix them before it does become an issue.

8a58933db0 Remove the CRYPTO_EX_new callback.
This callback is never used. The one caller I've ever seen is in Android
code which isn't built with BoringSSL and it was a no-op.

It also doesn't actually make much sense. A callback cannot reasonably
assume that it sees every, say, SSL_CTX created because the index may be
registered after the first SSL_CTX is created. Nor is there any point in
an EX_DATA consumer in one file knowing about an SSL_CTX created in
completely unrelated code.

Replace all the pointers with a typedef to int*. This will ensure code
which passes NULL or 0 continues to compile while breaking code which
passes an actual function.

This simplifies some object creation functions which now needn't worry
about CRYPTO_new_ex_data failing. (Also avoids bouncing on the lock, but
it's taking a read lock, so this doesn't really matter.)

c3ef76f327 Compatibility changes for wpa_supplicant and OpenSSH.
OpenSSH, especially, does some terrible things that mean that it needs
the EVP_CIPHER structure to be exposed ☹. Damian is open to a better API
to replace this, but only if OpenSSL agree too. Either way, it won't be
happening soon.

eb7d2ed1fe Add visibility rules.
This change marks public symbols as dynamically exported. This means
that it becomes viable to build a shared library of libcrypto and libssl
with -fvisibility=hidden.

On Windows, one not only needs to mark functions for export in a
component, but also for import when using them from a different
component. Because of this we have to build with
|BORINGSSL_IMPLEMENTATION| defined when building the code. Other
components, when including our headers, won't have that defined and then
the |OPENSSL_EXPORT| tag becomes an import tag instead. See the #defines
in base.h

In the asm code, symbols are now hidden by default and those that need
to be exported are wrapped by a C function.

In order to support Chromium, a couple of libssl functions were moved to
ssl.h from ssl_locl.h: ssl_get_new_session and ssl_update_cache.

449f16b947 Change ECDSA_METHOD's size() to group_order_size()
The |size| method was documented to return the same as |ECDSA_size| -
the max size of an ECDSA signature. However, this involves some ASN.1
calculations which is best done once. What custom implementations want
to give is the size of the group order on which the ASN.1 computations
are based.

This change switches the |size| method to allow that.

4c921e1bbc Move public headers to include/openssl/
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.
