bug#21415: 25.0.50; Emacs Trunk -- pixelwise width/height for x-create-frame

[Keith David Bershatsky]

I applied the patch named `maximize_and_trace.diff` and built Emacs --with-ns.  
I was surprised to see that `toggle-frame-maximized` actually worked, which is 
something I had never seen before on OSX.

My standard stuff that I normally use appears to be working okay -- e.g., 
`default-frame-alist` with pixel specifications for height/width and courier 
font are working correctly.

I'm not a programmer, but I'd be happy to run some layman's tests (if you need) 
on the build with OSX 10.6.8.
