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.

7e7af0bc51 When the underlying BIO_write() fails to send a datagram, we leave the
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

requested by setting SSL_MODE_RELEASE_BUFFERS anyway).

fbeaa3c47d Update util/ck_errf.pl script, and have it run automatically
during "make errors" and thus during "make update".

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.

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.

a661b65357 New functions SSL[_CTX]_set_msg_callback().
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'
that enable a message callback that displays all protocol messages.


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.

Fix SSL[_CTX]_ctrl prototype (void * instead of char * for generic
pointer).

Add/update some OpenSSL copyright notices.

bf21446a2a Add per-SSL 'msg_callback' with 'msg_callback_arg'.
Both have per-SSL_CTX defaults.
These new values can be set by calling SSL[_CTX]_[callback_]ctrl
with codes SSL_CTRL_SET_MSG_CALLBACK and SSL_CTRL_SET_MSG_CALLBACK_ARG.

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.
