[v2] ui/cocoa: Use NSWindow's ability to resize

This change brings two new features:
- The window will be resizable if "Zoom To Fit" is eanbled
- The window can be made full screen by clicking full screen button
  provided by the platform. (The left-top green button.)

While this is better for consistency with other apps is it a potential 
usability issue that a window bar may appear when you move the mouse to 
the top of the full screen window (where guests often have a menu bar that 
this could make harder to use)? (Haven't tested it so don't know how it 
actually works.)

You could override removeTrackingArea here then you would not have 
addTrackingArea vs. removeTrackingRect and that's the way NSTrackingArea 
docs also suggest.

What does the above function do? Is there a more straghtforward way to 
write this or add a comment because it's a bit confusing this way.

It says updateTrackingAreas can be overridden, but  decided to hook
the code to modify the guest display state instead because it should
be synchronized with trackingArea.

What about renaming this method fixZoomedFullScreenSizeAspectRatio?

I've missed that but now you pointed to it I have a comment about that.

Indeed it means updateTrackingAreas but I don't think it says you can't 
override removeTrackingArea so you could still do that as long as you call 
the original method then do whatever else is needed. Doing it in another 
method works but breaks the symmetry of add and remove so you have to 
remember to use another method to remove the tracking area than what you'd 
normally use. That's why I thought overriding the remove method could be 
cleaner.

Maybe it's better to just add a comment. The longer name still leaves one 
guessing. Maybe fullScreenSizeKeepingAspectRatio is shorter and still says 
what it should do but a comment can be as long as it has to be to say what 
it does. But something like this seems more straightforward to me:

double aspect = (double)screen.width / screen.height;
if (proposedSize.height * aspect <= proposedSize.width) {
     proposedSize.width = proposedSize.height * aspect;
} else {
     proposedSize.height = proposedSize.width / aspect;
}
return proposedSize;

removeTrackingArea: receives a tracking area to be removed, but we are
removing a particular tracking area in this case. See the use of the
method in frameUpdated. The symmetry of add and remove is in
frameUpdated; it sends addTrackingArea: and removeTrackingArea:.

fullScreenSizeKeepingAspectRatio is somewhat misleading because it is
modifying the aspect ratio of the given size. Do you think the name is
still prefered, or do you have another idea? Maybe should we just add
a comment and leave the name as is?

Having another division to calculate aspect results in a loss of
precision. Understanding its consequences is much harder than
understanding the current code in my opinion. (On the contrary, it is
quite obvious that screen_width * proposedSize.height will not
overflow. CGFloat is 64 bit in the supported systems.)

As I said before a comment would be enough so not changing the method name 
just adding a comment is fine. As for precision it will be converted to 
int at the end so not very likely to get different result when doing 
calculation in double, the integer part is likely the same. But I'm OK 
with your way with a comment as well.

You can disregard my other comments, I did not read the patch carefully 
enough so I've missed the details. Sorry for the noise.
