This was done by the following
find . -name '*.[ch]' | /tmp/pl
where /tmp/pl is the following three-line script:
print unless $. == 1 && m@/\* .*\.[ch] \*/@;
close ARGV if eof; # Close file to reset $.
And then some hand-editing of other files.

The function RECORD_LAYER_clear() is supposed to clear the contents of the
RECORD_LAYER structure, but retain certain data such as buffers that are
allocated. Unfortunately one buffer (for compression) got missed and was
inadvertently being wiped, thus causing a memory leak.
In part this is due to the fact that RECORD_LAYER_clear() was reaching
inside SSL3_BUFFERs and SSL3_RECORDs, which it really shouldn't. So, I've
rewritten it to only clear the data it knows about, and to defer clearing
of SSL3_RECORD and SSL3_BUFFER structures to SSL_RECORD_clear() and the
new function SSL3_BUFFER_clear().

This commit changes the way that we do server side protocol version
negotiation. Previously we had a whole set of code that had an "up front"
state machine dedicated to the negotiating the protocol version. This adds
significant complexity to the state machine. Historically the justification
for doing this was the support of SSLv2 which works quite differently to
SSLv3+. However, we have now removed support for SSLv2 so there is little
reason to maintain this complexity.
The one slight difficulty is that, although we no longer support SSLv2, we
do still support an SSLv3+ ClientHello in an SSLv2 backward compatible
ClientHello format. This is generally only used by legacy clients. This
commit adds support within the SSLv3 code for these legacy format
ClientHellos.
Server side version negotiation now works in much the same was as DTLS,
i.e. we introduce the concept of TLS_ANY_VERSION. If s->version is set to
that then when a ClientHello is received it will work out the most
appropriate version to respond with. Also, SSLv23_method and
SSLv23_server_method have been replaced with TLS_method and
TLS_server_method respectively. The old SSLv23* names still exist as
macros pointing at the new name, although they are deprecated.
Subsequent commits will look at client side version negotiation, as well of
removal of the old s23* code.

Fix up various things that were missed during the record layer work. All
instances where we are breaking the encapsulation rules.
