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.
to go the monolith way (does anyone do that these days?).
NOTE: a few applications are missing in this commit. I've a few more
changes in them that I haven't tested yet.
record-oriented fashion. That means that every write() will write a
separate record, which will be read separately by the programs trying
to read from it. This can be very confusing.
The solution is to put a BIO filter in the way that will buffer text
until a linefeed is reached, and then write everything a line at a
time, so every record written will be an actual line, not chunks of
lines and not (usually doesn't happen, but I've seen it once) several
lines in one record. Voila, BIO_f_linebuffer() is born.
Since we're so close to release time, I'm making this VMS-only for
now, just to make sure no code is needlessly broken by this. After
the release, this BIO method will be enabled on all other platforms as
well.
