TLS detection for node.js

	/*
	* Autodetect if SSL/TLS is used by having a look at the first incoming bytes
	* This technique is from http://webview.jabberd.org/cgi-bin/viewvc.cgi/trunk/jadc2s/clients.cc?view=markup
	*
	* used heuristic:
	* - an incoming connection using SSLv3/TLSv1 records should start with 0x16
	* - an incoming connection using SSLv2 records should start with the record size
	* and as the first record should not be very big we can expect 0x80 or 0x00 (the MSB is a flag)
	* - everything else is considered to be unencrypted
