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