SSL: do not treat SSL handshake as request. The request object will not be created until SSL handshake is complete. This simplifies adding another connection handler that does not need request object right after handshake (e.g., SPDY). There are also a few more intentional effects: - the "client_header_buffer_size" directive will be taken from the server configuration that was negotiated by SNI; - SSL handshake errors and timeouts are not logged into access log as bad requests; - ngx_ssl_create_connection() is not called until the first byte of ClientHello message was received. This also decreases memory consumption if plain HTTP request is sent to SSL socket.
