Changes for post_client_hello_function(). The extensions are now parsed in a

callback friendly way. Extensions are now split to APPLICATION and TLS layer.
The APPLICATION layer extensions are parsed before the callback function is called
and the others afterwards. This allows the callback to change the behavior of the
TLS layer parsers by using the data of the APPLICATION layer extensions.

Currently the only application layer extension is defined to be the server name
indication extension.
