1a0a8b6760 Make EVP_MD_CTX size functions return size_t.
The EVP_MD versions do, so the types should bubble up.

34248d4cb7 Get rid of err function codes.
Running make_errors.go every time a function is renamed is incredibly
tedious. Plus we keep getting them wrong.

Instead, sample __func__ (__FUNCTION__ in MSVC) in the OPENSSL_PUT_ERROR macro
and store it alongside file and line number. This doesn't change the format of
ERR_print_errors, however ERR_error_string_n now uses the placeholder
"OPENSSL_internal" rather than an actual function name since that only takes
the uint32_t packed error code as input.

This updates err scripts to not emit the function string table. The
OPENSSL_PUT_ERROR invocations, for now, still include the extra
parameter. That will be removed in a follow-up.

65ee9b7ce9 Remove EVP_PKEY_HMAC.
This removes EVP_PKEY_HMAC and all the support code around it. EVP_MD requires
a lot of extra glue to support HMAC. This lets us prune it all away.

As a bonus, it removes a (minor) dependency from EVP to the legacy ASN.1 stack.

e216288109 Unexport and prune EVP_MD_CTX flags.
The only flag is EVP_MD_CTX_FLAG_NO_INIT and no good can possibly come of
anyone outside EVP_PKEY_HMAC calling it. (And indeed no one calls it.
EVP_MD_CTX_set_flags has a caller in wpa_supplicant, but it uses
EVP_MD_CTX_FLAG_NON_FIPS_ALLOW which we don't define. The call is guarded by a
pair of ifdefs for some FIPS mode wpa_supplicant.)

c82a00d818 Replace MD5 in examples with SHA-256.
Avoiding superflous references to MD5 makes it easier to audit the code
to find unsafe uses of it. It also avoids subtly encouraging users to
choose MD5 instead of a better alternative.

6e8fbfecd0 Remove crypto/obj dependencies from low-level crypto tests.
The only dependency the low-level crypto modules have on code in
crypto/obj is their use of OBJ_nid2sn, which is trivial to avoid.
This facilitates future simplification of crypto/obj, including
possibly the removal of functions like OBJ_nid2sn and the complex
build infrastructure that supports them.

This change also removes EVP_CIPHER_name and EVP_MD_name.

that. Also skip a/an/deprecated: in markupFirstWord and process pipe words in

00505ec2e1 Add EVP_md5_sha1.
Use it in ssl3_cert_verify_hash so signing a pre-TLS-1.2 handshake hash can go
through RSA_sign and be intercepted via RSA_METHOD appropriately. This avoids
Windows needing to intercept sign_raw. (CAPI keys cannot provide sign_raw,
unless the input size happens to be that of NID_md5_sha1.)

Also use it in processing ServerKeyExchange to avoid special-casing RSA.

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.

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.
