354	This is the deal:
355
356	Four new options are available:
357	- VNCAddress4 -> IPv4 address to use
358	- VNCPort4 -> IPv4 Port to use
359	- VNCAddress6 -> IPv6 address to use
360	- VNCPort6 -> IPv6 port to use
361
362	By default we prefer IPv6 over IPv4.
363
364	The address length can be unlimited as the interface identifier is not
365	limited by any specs - if this is wrong, and someone knows the line
366	and the RFC number, i'd appreciate a message :)
367
368	THE MAXIMUM LENGTH OF THE RETURNED VALUES MUST NOT BE GREATER THAN:
369
370	--> VBOX_ADDRESS_OPTION_MAX <--
371
372	which is defined at the top of this file.
373
374	The way to determine which address to use is as follows:
375
376	1st - get address information from VRDEProperties
377	"TCP/Address"
378	"TCP/Ports"
379
380	2nd - if the address information is IPv4 get VNCAddress6 and VNCPort6
381	2nd - if the address information is IPv6 get VNCAddress4 and VNCPort4
382	2nd - if the address information is EMPTY and TCP/Ports returns 3389,
383	check both, VNCAddress4 and VNCAddress6 as well as the ports.
384	3389 is not a valid VNC port, therefore we assume it's not
385	been set
386
387	If one of the addresses is empty we assume to listen on any
388	interface/address for that protocol. In other words:
389	IPv4: 0.0.0.0
390	IPv6: ::
391
392	2nd - if everything is empty -> listen on all interfaces
393
394	3rd - check if the addresses are valid hand them to libvncserver
395	to open the initial sockets.
396
397	4th - after the sockets have been opened, the used port of the
398	address/protocol in TCP/Address is returned.
399	if TCP/Address is empty, prefer IPv6
