RT2772: accept empty SessionTicket

RFC 5077 section 3.3 says: If the server determines that it does not
want to include a ticket after it has included the SessionTicket
extension in the ServerHello, then it sends a zero-length ticket in the
NewSessionTicket handshake message.

Previously the client would fail upon attempting to allocate a
zero-length buffer. Now, we have the client ignore the empty ticket and
keep the existing session.

Make BUF_strndup() read-safe on arbitrary inputs

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.

Fix DTLS session ticket renewal

A DTLS client will abort a handshake if the server attempts to renew the
session ticket. This is caused by a state machine discrepancy between DTLS
and TLS discovered during the state machine rewrite work.

The bug can be demonstrated as follows:

Start a DTLS s_server instance:
openssl s_server -dtls

Start a client and obtain a session but no ticket:
openssl s_client -dtls -sess_out session.pem -no_ticket

Now start a client reusing the session, but allow a ticket:
openssl s_client -dtls -sess_in session.pem

The client will abort the handshake.

Fix "make test" seg fault with SCTP enabled

When config'd with "sctp" running "make test" causes a seg fault. This is
actually due to the way ssltest works - it dives under the covers and frees
up BIOs manually and so some BIOs are NULL when the SCTP code does not
expect it. The simplest fix is just to add some sanity checks to make sure
the BIOs aren't NULL before we use them.

This problem occurs in master and 1.0.2. The fix has also been applied to
1.0.1 to keep the code in sync.

Fix SSL_set_session_ticket_ext when used with SSLv23_method

The function SSL_set_session_ticket_ext can be used to set custom session
ticket data passed in the initial ClientHello. This can be particularly
useful for EAP-FAST. However, when using SSLv23_method, the session does
not get created until the ServerHello has been received. The extension code
will only add the SessionTicket data to the ClientHello if a session already
exists. Therefore SSL_set_session_ticket_ext has no impact when used in
conjunction with SSLv23_method. The solution is to simply create the session
during creation of the ClientHello instead of waiting for the ServerHello.

This commit fixes the test failure introduced by the previous commit.
