e167976126 Make EVP_DigestVerifyFinal return only zero or one.
It was already almost there. Just a malloc failure away. now all the
EVP_Digest{Sign,Verify}* functions may be used without worrying about -1 return
values.

0248889950 Don't mix and match libraries and errors.
The same library code applies for both the error and the function, so modules
cannot easily report errors from each other. Switch evp/algorithm.c's error
codes to the EVP library. Remove the original error codes so it's obvious some
changes are needed.

- X509_R_DIGEST_AND_KEY_TYPE_NOT_SUPPORTED -> EVP_R_DIGEST_AND_KEY_TYPE_NOT_SUPPORTED
  ASN1_R_DIGEST_AND_KEY_TYPE_NOT_SUPPORTED -> EVP_R_DIGEST_AND_KEY_TYPE_NOT_SUPPORTED
  (Actually, the X509 version of this error code doesn't exist in OpenSSL. It should
   have been ASN1.)

- ASN1_R_UNKNOWN_SIGNATURE_ALGORITHM -> EVP_R_UNKNOWN_SIGNATURE_ALGORITHM

- ASN1_R_WRONG_PUBLIC_KEY_TYPE -> EVP_R_WRONG_PUBLIC_KEY_TYPE

- ASN1_R_UNKNOWN_MESSAGE_DIGEST_ALGORITHM -> EVP_R_UNKNOWN_MESSAGE_DIGEST_ALGORITHM

8f160a680b Add EVP_DigestVerifyInitFromAlgorithm and EVP_DigestSignAlgorithm.
Factor the AlgorithmIdentifier portions of ASN1_item_sign and ASN1_item_verify
out. This makes it possible to initialize a signature context from an
AlgorithmIdentifier without needing the data parsed into an ASN1_ITEM/void*
pair and reserialized.

c44d2f4cb8 Convert all zero-argument functions to '(void)'
Otherwise, in C, it becomes a K&R function declaration which doesn't actually
type-check the number of arguments.

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.

5129e2d695 Align EVP return values with BoringSSL convention.
Where possible, functions should return one for success and zero for
error. The use of additional negative values to indicate an error is,
itself, error prone.

This change fixes many EVP functions to remove the possibility of
negative return values. Existing code that is testing for <= 0 will
continue to function, although there is the possibility that some code
was differentiating between negative values (error) and zero (invalid
signature) for the verify functions and will now show the wrong error
message.

ecc0ce7e67 Introduce EVP_PKEY_is_opaque to replace RSA_METHOD_FLAG_NO_CHECK.
Custom RSA and ECDSA keys may not expose the key material. Plumb and "opaque"
bit out of the *_METHOD up to EVP_PKEY. Query that in ssl_rsa.c to skip the
sanity checks for certificate and key matching.

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.
