Stop DTLS servers asking for unsafe legacy renegotiation

If a DTLS client that does not support secure renegotiation connects to an
OpenSSL DTLS server then, by default, renegotiation is disabled. If a
server application attempts to initiate a renegotiation then OpenSSL is
supposed to prevent this. However due to a discrepancy between the TLS and
DTLS code, the server sends a HelloRequest anyway in DTLS.

This is not a security concern because the handshake will still fail later

Don't treat a bare OCTETSTRING as DigestInfo in int_rsa_verify

The function int_rsa_verify is an internal function used for verifying an
RSA signature. It takes an argument |dtype| which indicates the digest type
that was used. Dependant on that digest type the processing of the
signature data will vary. In particular if |dtype == NID_mdc2| and the
signature data is a bare OCTETSTRING then it is treated differently to the
default case where the signature data is treated as a DigestInfo (X509_SIG).

Due to a missing "else" keyword the logic actually correctly processes the
OCTETSTRING format signature first, and then attempts to continue and
process it as DigestInfo. This will invariably fail because we already know
that it is a bare OCTETSTRING.

This failure doesn't actualy make a real difference because it ends up at
the |err| label regardless and still returns a "success" result. This patch
just cleans things up to make it look a bit more sane.

BUF_strndup was calling strlen through BUF_strlcpy, and ended up reading
past the input if the input was not a C string.

Make it explicitly part of BUF_strndup's contract to never read more

RT3823: Improve the robustness of event logging

There are a couple of minor fixes here:

1) Handle the case when RegisterEventSource() fails (which it may for
various reasons) and do the work of logging the event only if it succeeds.

2) Handle the case when ReportEvent() fails and do our best in debug builds
to at least attempt somehow indicate that something has gone wrong. The
typical situation would be someone running tools like DbMon, DBWin32,
DebugView or just having the debugger attached. The intent is to make sure
that at least some data will be captured so that we can save hours and days
of debugging time.

3) Minor fix to change the MessageBox() flag to MB_ICONERROR. Though the
value of MB_ICONERROR is the same value as MB_ICONSTOP, the intent is
better conveyed by using MB_ICONERROR.

Testing performed:

1) Clean compilation for debug-VC-WIN32 and VC-WIN32.

2) Good test results (nmake -f ms\ntdll.mak test) for debug-VC-WIN32 and
VC-WIN32.

3) Stepped through relevant changes using WinDBG and exercised the impacted
code paths.

Make sure OPENSSL_cleanse checks for NULL

In master we have the function OPENSSL_clear_free(x,y), which immediately
returns if x == NULL. In <=1.0.2 this function does not exist so we have to
do:
OPENSSL_cleanse(x, y);
OPENSSL_free(x);

However, previously, OPENSSL_cleanse did not check that if x == NULL, so
the real equivalent check would have to be:
if (x != NULL)
    OPENSSL_cleanse(x, y);
OPENSSL_free(x);

It would be easy to get this wrong during cherry-picking to other branches
and therefore, for safety, it is best to just ensure OPENSSL_cleanse also
checks for NULL.
