[A part of this change affecting ssl/s3_lib.c was accidentally commited
separately, together with a compilation fix for that file;
see s3_lib.c CVS revision 1.133 (http://cvs.openssl.org/chngview?cn=19855).]

Support for abbreviated handshakes when renegotiating.

1.0.0. Original fix was on 2007-Mar-09 and had the log message: "Fix kerberos
ciphersuite bugs introduced with PR:1336."

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.

ctrl is incorrectly implemented (e.g. some versions of Apache). As a workaround
call both BIO_CTRL_INFO and BIO_CTRL_WPENDING if it returns zero. This should
both address the original bug and retain compatibility with the old behaviour.

server attempts to renegotiate with an unpatched client.

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).

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.
