337	This is the deal:
338
339	Four new options are available:
340	- VNCAddress4 -> IPv4 address to use
341	- VNCPort4 -> IPv4 Port to use
342	- VNCAddress6 -> IPv6 address to use
343	- VNCPort6 -> IPv6 port to use
344
345	By default we prefer IPv6 over IPv4.
346
347	The address length can be unlimited as the interface identifier is not
348	limited by any specs - if this is wrong, and someone knows the line
349	and the RFC number, i'd appreciate a message :)
350
351	THE MAXIMUM LENGTH OF THE RETURNED VALUES MUST NOT BE GREATER THAN:
352
353	--> VBOX_ADDRESS_OPTION_MAX <--
354
355	which is defined at the top of this file.
356
357	The way to determine which address to use is as follows:
358
359	1st - get address information from VRDEProperties
360	"TCP/Address"
361	"TCP/Ports"
362
363	2nd - if the address information is IPv4 get VNCAddress6 and VNCPort6
364	2nd - if the address information is IPv6 get VNCAddress4 and VNCPort4
365	2nd - if the address information is EMPTY and TCP/Ports returns 3389,
366	check both, VNCAddress4 and VNCAddress6 as well as the ports.
367	3389 is not a valid VNC port, therefore we assume it's not
368	been set
369
370	If one of the addresses is empty we assume to listen on any
371	interface/address for that protocol. In other words:
372	IPv4: 0.0.0.0
373	IPv6: ::
374
375	2nd - if everything is empty -> listen on all interfaces
376
377	3rd - check if the addresses are valid hand them to libvncserver
378	to open the initial sockets.
379
380	4th - after the sockets have been opened, the used port of the
381	address/protocol in TCP/Address is returned.
382	if TCP/Address is empty, prefer IPv6
