Fixes for DTLS timeout bug

7a014dceb6 Add support for magic cipher suite value (MCSV). Make secure renegotiation 
work in SSLv3: initial handshake has no extensions but includes MCSV, if
server indicates RI support then renegotiation handshakes include RI.

NB: current MCSV value is bogus for testing only, will be updated when we
have an official value.

Change mismatch alerts to handshake_failure as required by spec.

Also have some debugging fprintfs so we can clearly see what is going on
if OPENSSL_RI_DEBUG is set.

4db3e88459 Firstly, the bitmap we use for replay protection was ending up with zero 
length, so a _single_ pair of packets getting switched around would
cause one of them to be 'dropped'.

Secondly, it wasn't even _dropping_ the offending packets, in the
non-blocking case. It was just returning garbage instead.

e2ac4732cd pqueue and dtls uses 64-bit values. Unfortunately, OpenSSL doesn't 
have a uniform representation for those over all architectures, so a
little bit of hackery is needed.
