Initial secure renegotiation documentation.

Check for memory allocation failures.

Change RI ctrl so it doesn't clash.

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.

Another mingw fix.

inline 64-bit assembler instructions. Normally it's inappropriate, because
signalling doesn't preserve upper halves of general purpose registers.
Meaning that it's only safe if signals are blocked for the time "wide"
code executes.
