Callers are required to use the wrappers now. They still need OPENSSL_EXPORT
since crypto and ssl get built separately in the standalone shared library
build.

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.

This introduces a per-RSA/DSA/DH lock. This is good for lock contention,
although pthread locks are depressingly bloated.

The use in s3_srvr.c doesn't care (it doesn't even have to be in bounds), but
it's good to have the value be initialized and not a function of the input.
(The old uninitialized case wasn't hit in s3_srvr.c because of the earlier
bounds check.)

This change extracts two, common parts of RSA_decrypt and RSA_sign into
a function called |private_transform|. It also allows this to be
overridden in a method, which is convenient for opaque keys that only
expose the raw RSA transform as it means that the padding code from
BoringSSL can be easily reimplemented.
One significant change here is that short RSA ciphertexts will no longer
be accepted. I think this is correct and OpenSSL has a comment about PGP
mistakenly stripping leading zeros. However, these is the possibility
that it could break something.

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.

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.

Although the PKCS#1 padding check is internally constant-time, it is not

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.
