algorithm matches current and give error if compression is disabled and
server requests it (shouldn't happen unless server is broken).

used compression algorithms in client hello (a legacy from when
the compression algorithm wasn't serialized with SSL_SESSION).

MCSV is now called SCSV.

Don't send SCSV if renegotiating.

Also note if RI is empty in debug messages.

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.
