I was playing around with 7.3.1 and found some more SSL problems. The
first, that I missed when checking over 7.3.1, was that the client
method was switched to SSLv23 along with the server. The SSLv23 client
method does SSLv2 by default, but can also understand SSLv3. In our
situation the SSLv2 backwords compatibility is really only needed on the
server. This is the first patch.
The last thing is that I found a way for the server to understand SSLv2
HELLO messages (sent by pre-7.3 clients) but then get them to talk
SSLv3. This is the last one.
