Previously EVP_EncodeUpdate returned a void. However there are a couple
of error conditions that can occur. Therefore the return type has been
changed to an int, with 0 indicating error and 1 indicating success.

SSH2 implementations which use DSA_do_verify() and ECDSA_do_verify() are given
the R and S values, and the data to be signed, by the client. Thus in order
to validate these signatures, SSH2 implementations will digest and sign
the data -- and then pass in properly provisioned DSA_SIG and ECDSA_SIG objects.
Unfortunately, the existing OpenSSL-1.1.0 APIs do not allow for directly setting
those R and S values in these objects, which makes using OpenSSL for such
SSH2 implementations much more difficult.

The function InitOnceExceuteOnce is the best way to support the
implementation of CRYPTO_THREAD_run_once() on Windows. Unfortunately
WinXP doesn't have it. To get around that we had two different
implementations: one for WinXP and one for later versions. Which one was
used was based on the value of _WIN32_WINNT.
This approach was starting to cause problems though because other parts of
OpenSSL assume _WIN32_WINNT is going to be 0x0501 and crashes were
occurring dependant on include file ordering. In addition a conditional
based on _WIN32_WINNT had made its way into a public header file through
commit 5c4328f. This is problematic because the value of this macro can
vary between OpenSSL build time and application build time.
The simplest solution to this mess is just to always use the WinXP version
of CRYPTO_THREAD_run_once(). Its perhaps slightly sub-optimal but probably
not noticably.

Since with SSL_VERIFY_NONE, the connection may continue and the
session may even be cached, we should save some evidence that the
chain was not sufficiently verified and would have been rejected
with SSL_VERIFY_PEER. To that end when a CT callback returs failure
we set the verify result to X509_V_ERR_NO_VALID_SCTS.
Note: We only run the CT callback in the first place if the verify
result is still X509_V_OK prior to start of the callback.

continue due to malloc failure. Also, when X509_verify_cert()
returns <= 0 make sure that the verification status does not remain
X509_V_OK, as a last resort set it it to X509_V_ERR_UNSPECIFIED,
just in case some code path returns an error without setting an
appropriate value of ctx->error.
