More robust fix and workaround for PR#1949. Don't try to work out if there
is any write pending data as this can be unreliable: always flush.

Although it will be many years before TLS v2.0 or later appears old versions
of servers have a habit of hanging around for a considerable time so best
if we handle this properly now.

stops applications that call CRYPTO_free_all_ex_data() prematurely leaking

Add options to output hash using older algorithm compatible with OpenSSL
versions before 1.0.0

1. Add provisional SCSV value.
2. Don't send SCSV and RI at same time.
3. Fatal error is SCSV received when renegotiating.

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

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.
