    Alan>     Move NS port toolbar handling to the window

Hi Alan, I tried this branch. I did

emacs -Q
(tool-bar-mode -1)
C-x 5 2

The second frame has the tool-bar disabled, but unlike master the
frame height is greater than the initial frame, and the frame title is
bigger as well, as if its height had not been adjusted after removing
the tool-bar.
