Include server name and RFC4507bis support.

_______________
Changes between 0.9.8e and 0.9.8f [xx XXX xxxx]
+
+ *) Add RFC4507 support to OpenSSL. This includes the corrections in
+ RFC4507bis. The encrypted ticket format is an encrypted encoded
+ SSL_SESSION structure, that way new session features are automatically
+ supported.
+
+ If a client application caches session in an SSL_SESSION support it
+ should automatically be supported because an extension includes the
+ ticket in the structure. The SSL_CTX structure automatically generates
+ keys for ticket protection in servers so again support should be possible
+ with no application modification.
+
+ If a client or server wishes to disable RFC4507 support then the option
+ SSL_OP_NO_TICKET can be set.
+
+ Add a TLS extension debugging callback to allow the contents of any client
+ or server extensions to be examined.
+ [Steve Henson]
+
+ *) Add initial support for TLS extensions, specifically for the server_name
+ extension so far. The SSL_SESSION, SSL_CTX, and SSL data structures now
+ have new members for a host name. The SSL data structure has an
+ additional member SSL_CTX *initial_ctx so that new sessions can be
+ stored in that context to allow for session resumption, even after the
+ SSL has been switched to a new SSL_CTX in reaction to a client's
+ server_name extension.
+
+ New functions (subject to change):
+
+ SSL_get_servername()
+ SSL_get_servername_type()
+ SSL_set_SSL_CTX()
+
+ New CTRL codes and macros (subject to change):
+
+ SSL_CTRL_SET_TLSEXT_SERVERNAME_CB
+ - SSL_CTX_set_tlsext_servername_callback()
+ SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG
+ - SSL_CTX_set_tlsext_servername_arg()
+ SSL_CTRL_SET_TLSEXT_HOSTNAME - SSL_set_tlsext_host_name()
+
+ openssl s_client has a new '-servername ...' option.
+
+ openssl s_server has new options '-servername_host ...', '-cert2 ...',
+ '-key2 ...', '-servername_fatal' (subject to change). This allows
+ testing the HostName extension for a specific single host name ('-cert'
+ and '-key' remain fallbacks for handshakes without HostName
+ negotiation). If the unrecogninzed_name alert has to be sent, this by
+ default is a warning; it becomes fatal with the '-servername_fatal'
+ option.
+
+ [Peter Sylvester, Remy Allais, Christophe Renou, Steve Henson]
*) Add AES and SSE2 assembly language support to VC++ build.

+ - The servername field is maintained together with the session cache.
+ - When a session is resumed, the servername call back invoked in order
+ to allow the application to position itself to the right context.
+ - The servername is acknowledged if it is new for a session or when
+ it is identical to a previously used for the same session.
+ Applications can control the behaviour. They can at any time
+ set a 'desirable' servername for a new SSL object. This can be the
+ case for example with HTTPS when a Host: header field is received and
+ a renegotiation is requested. In this case, a possible servername
+ presented in the new client hello is only acknowledged if it matches
+ the value of the Host: field.
+ - Applications must use SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION
+ if they provide for changing an explicit servername context for the session,
+ i.e. when the session has been established with a servername extension.
+ - On session reconnect, the servername extension may be absent.
