ppc64-mont.pl: clarify comment and fix spelling.

for kind of installation suggested in ticket #2003 from August. What it
effectively does now, is arrange pre-configured default $libdir value.
Note that it also fixes ENGINESDIR, i.e. harmonizes it with install path.

just like a "real" server making it easier to trace any problems.

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.
