50a095ed16 Updates to conform with draft-ietf-tls-renegotiation-03.txt:
1. Add provisional SCSV value.
2. Don't send SCSV and RI at same time.
3. Fatal error is SCSV received when renegotiating.

MCSV is now called SCSV.

Don't send SCSV if renegotiating.

Dr. Stephen Henson
7a014dceb6 Add support for magic cipher suite value (MCSV). Make secure renegotiation
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.

e0db2eed8d Correct and enhance the behaviour of "internal" session caching as it
relates to SSL_CTX flags and the use of "external" session caching. The
existing flag, "SSL_SESS_CACHE_NO_INTERNAL_LOOKUP" remains but is
supplemented with a complimentary flag, "SSL_SESS_CACHE_NO_INTERNAL_STORE".
The bitwise OR of the two flags is also defined as
"SSL_SESS_CACHE_NO_INTERNAL" and is the flag that should be used by most
applications wanting to implement session caching *entirely* by its own
provided callbacks. As the documented behaviour contradicted actual
behaviour up until recently, and since that point behaviour has itself been
inconsistent anyway, this change should not introduce any compatibility
problems. I've adjusted the relevant documentation to elaborate about how
this works.

Kudos to "Nadav Har'El" <nyh@math.technion.ac.il> for diagnosing these
anomalies and testing this patch for correctness.

7b63c0fa8c Reorder inclusion of header files:
des_old.h redefines crypt:
#define crypt(b,s)\
        DES_crypt((b),(s))

This scheme leads to failure, if header files with the OS's true definition
of crypt() are processed _after_ des_old.h was processed. This is e.g. the
case on HP-UX with unistd.h.
As evp.h now again includes des.h (which includes des_old.h), this problem
only came up after this modification.
Solution: move header files (indirectly) including e_os.h before the header
files (indirectly) including evp.h.
