Order chronologically: move entry for recent s2_clnt.c/s2_srvr.c fixes 

(nearly) to the top.

Move msg_callback entry to the top as the implementation for SSL 2.0
is based on the s2_clnt.c/s2_srvr.c changes.

     protocol version  according to which the SSL library interprets

     the current protocol message (SSL2_VERSION, SSL3_VERSION, or

     TLS1_VERSION).  'content_type' is 0 in the case of SSL 2.0, or

     the content type as defined in the SSL 3.0/TLS 1.0 protocol

     specification (change_cipher_spec(20), alert(21), handshake(22)).

     'buf' and 'len' point to the actual message, 'ssl' to the

     SSL object, and 'arg' is the application-defined value set by

     SSL[_CTX]_set_msg_callback_arg().



     'openssl s_client' and 'openssl s_server' have new '-msg' options

     to enable a callback that displays all protocol messages.

  *) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake

     messages are stored in a single piece (fixed-length part and

     variable-length part combined) and fix various bugs found on the way.

     soon as the corresponding static library is finished, and thereby get

     openssl and the test programs linked against the shared library.
