Setting SSL_MODE_RELEASE_BUFFERS should be ignored for DTLS, but instead causes
the program to crash. This is due to missing version checks and is fixed with
this patch.

At present only RSA key exchange ciphersuites work with TLS v1.2 as the
new signature format is not yet implemented.
Also, add missing CHANGES entry for CVE-2009-3245 (code changes submitted to this branch on 23 Feb 2010),
and further harmonize this version of CHANGES with the versions in the current branches.

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.
offending record queued as 'pending'. The DTLS code doesn't expect this,
and we end up hitting an OPENSSL_assert() in do_dtls1_write().
The simple fix is just _not_ to leave it queued. In DTLS, dropping
packets is perfectly acceptable -- and even preferable. If we wanted a
service with retries and guaranteed delivery, we'd be using TCP.

Also, get rid of compile-time switch OPENSSL_NO_RELEASE_BUFFERS
because it was rather pointless (the new behavior has to be explicitly
requested by setting SSL_MODE_RELEASE_BUFFERS anyway).

Fix lots of bugs that util/ck_errf.pl can detect automatically.
Various others of these are still left to fix; that's why
"make update" will complain loudly when run now.
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.

New macros SSL[_CTX]_set_msg_callback_arg().
Message callback imlementation for SSL 3.0/TLS 1.0 (no SSL 2.0 yet).
New '-msg' option for 'openssl s_client' and 'openssl s_server'

In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert if
client_version is smaller than the protocol version in use.
Also change ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0
if the client demanded SSL 3.0 but only TLS 1.0 is enabled; then the
client will at least see that alert.

Both have per-SSL_CTX defaults.
These new values can be set by calling SSL[_CTX]_[callback_]ctrl

So far, the callback is never actually called.
Also rearrange some SSL_CTX struct members (some exist just in
SSL_CTXs, others are defaults for SSLs and are either copied
during SSL_new, or used if the value in the SSL is not set;
these three classes of members were not in a logical order),
and add some missing assignments to SSL_dup.
