Full-height, full-width, and maximized windows now cover the
        entire screen (except the menu bar), including the part where the
        system dock is placed. The system zoom animation is no longer
        used.

        Made NonMaximized->FullWidth->FullHeight->NonMaximized restore the
        original size.

        * nsterm.m (ns_menu_bar_height): New function, return height of
        the menu bar, or 0 when it's hidden.
        * nsterm.m (constrain_frame_rect): New function for constraining a
        frame.
        * nsterm.m (ns_constrain_all_frames): Set frame size explicitly
        rather than relying on the system doing it for us by writing back
        the current frame size.
        * nsterm.m (windowWillUseStandardFrame): Register non-maximized
        width or height as new user size. When entering full width or
        height, the other size component is taken from the user size.
        * nsterm.m (fullscreenState): New method for accessing the
        fullscreen state.
        * nsterm.m (constrainFrameRect): Restrict frame to be placed under
        the menu bar, if present. The old version, sometimes, restricted
        the height of a frame to the screen, this version never does this.
        * nsterm.m (zoom): Perform zoom by setting the frame to the full
        size of the screen (minus the menu bar). The default system
        function, with the zoom animation, is no longer used, as the final
        frame size doesn't cover the entire screen.



        Rework how to constrain resizing to the character grid. The old
        system used "resizeIncrements" in NSWindows. However, once a frame
        was resized so that it was not aligned to the text grid, it
        remained unaligned even after a resize. In addition, it conflicted
        when resizing a fullheight window.

        * nsterm.m (windowWillResize): Restrict frame size to text grid,
        unless when pixelwise frame resizing is enabled.
        * nsterm.m (updateFrameSize, initFrameFromEmacs)
        (toggleFullScreen, handleFS): Don't set resizeIncrements.


        Redesign the NS trace system. The call structure is represented
        using indentations and vertical lines. The NSTRACE macro accepts
        printf-style arguments. New macros for printing various
        information.

        * nsterm.h (NSTRACE_ENABLED): Macro to enable trace system.
        * nsterm.h (NSTRACE, NSTRACE_WHEN, NSTRACE_UNLESS): Macros to
        start a new block (typically a function), accept printf-style
        arguments.
        * nsterm.h (NSTRACE_MSG): Macro for extra information, accepts
        printf-style arguments.
        * nsterm.h (NSTRACE_what): Macros for printing various types.
        * nsterm.h (NSTRACE_FMT_what): Macro with printf format string
        snippets.
        * nsterm.h (NSTRACE_ARG_what): Macros for passing printf-style
        arguments, corresponds to NSTRACE_FMT_what.
        * nsterm.h (NSTRACE_RETURN): Macro to print return value, accept
        printf-style arguments.
        * nsterm.h (NSTRACE_RETURN_what): Macros to print return value for
        various types.

	* nsterm.m: Remove old NSTRACE macro.
	* nsterm.m (nstrace_num): Trace counter.
        * nsterm.m (nstrace_depth): Current call depth.
        * nsterm.m (nstrace_leave): NSTRACE support function, called when
        the local variable "nstrace_enabled" goes out of scope using the
        "cleanup" extension.
        * nsterm.m (ns_print_fullscreen_type_name): NSTRACE_FSTYPE support
        function.
