integers are nowadays always represented by the same (positive) number
on all platforms.
(read-key-empty-map): New const.
(read-key-delay): New var.
(read-key): New function.
(force-mode-line-update): Use with-current-buffer.
(locate-user-emacs-file): Don't forget to abbreviate the file name.
(start-process-shell-command, start-file-process-shell-command):
Discourage the use of command-args.
* processes.texi (Asynchronous Processes): Adjust arglist of
start-process-shell-command and start-file-process-shell-command.
(Edebug Execution Modes): Sit-for affects continue mode too.
(Jumping): Use `forward-sexp' rather than its keybinding.
(Edebug Misc): Fix Q binding.
(Edebug Eval): Remove cl version.
(Printing in Edebug): Clarify print-length etc.
(Instrumenting Macro Calls): Defopt edebug-eval-macro-args.
(Specification List): Remove edebug-unwrap findex entry.
(Specification Examples): defmacro is actually not the same as defun.
Escape "`" in example.
* frame.c: Qmaximized is new.
(x_set_frame_parameters): Do not handle fullscreen specially.
Only set width and height if explicitly set.
(x_set_fullscreen): Handle Qmaximized.
(x_set_font, x_figure_window_size): Do not handle fullscreen specially.
(syms_of_frame): Initialize Qmaximized.
* frame.h (fullscreen_type): Add FULLSCREEN_MAXIMIZED. Declare
Qfullwidth, Qfullheight, Qfullboth, Qmaximized.
* xterm.c (handle_one_xevent): Remove call to x_check_fullscreen
for Expose event. Add call to x_check_fullscreen for MapNotify event.
Remove all code w.r.t. fullscreen from ConfigureNotify event. Do not
set gravity to NorthWestGravity when USE_GTK.
(set_wm_state): New function.
(do_ewmh_fullscreen): Use set_wm_state. Also handle FULLSCREEN_MAXIMIZED.
(x_handle_net_wm_state): Handle FULLSCREEN_MAXIMIZED.
(x_check_fullscreen): Simplify so we only handle EMWH type of fullscreen
or the case when no window manager is running. That means remove calls
to x_real_positions and x_fullscreen_adjust.
* gtkutil.c (flush_and_sync, x_wm_size_hint_off): Remove.
(xg_frame_set_char_size): Remove calls to x_wm_size_hint_off and
flush_and_sync.
(xg_height_changed): New function.
(xg_create_frame_widgets): Remove call to gtk_widget_set_size_request
and gtk_window_set_policy. Set frame gravity after parsing the geometry
string.

(xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
(update_frame_tool_bar, free_frame_tool_bar): Call xg_height_changed.
Remove calls to xg_frame_set_char_size.
* startup.el (command-line-x-option-alist): Add -mm and --maximized.
* NEWS: Mention maximized.
* frames.texi (Size Parameters): Mention maximized for fullscreen.
* xresources.texi (Table of Resources): Mention maximized for
fullscreen.
* cmdargs.texi (Window Size X): -mm/--maximized is new.
