With proper notifications, plus an accessor method for that state. This
allows client to just listen to notify::is-maximized instead of tracking
window-state-event.

This leads to disastruous results, since each menu is itself
in a GtkWindow, so holding down the menu key leads to a neverending
cascade of menus on top of menus.

The window-dragging code had a number of issues: The code was
starting a drag on every button press, never bothering to cancel
them. This leads to the odd hand cursor occurring between the two
clicks to maximize. We relied on GDK's multi-click detection, which
gives us triple-clicks when we really want sequences of double-clicks.
Lastly, we didn't propery restrict double-click handling to the primary
button, so e.g. if you had a window on an empty workspace, double-right
click on the titlebar would maximize it, which is not intended.
This commit solves all three problem by a doing our own double-click
detection, and only starting a drag when the pointer goes out of
'double-click range'. We change the way dragging is implemented for
menubars and toolbars to just letting events bubble up, so they
get the same behaviour as the titlebar. To make this work, we
have to select for pointer motion events in a few more places.
gtkapplication.c has turned into a bit of an #ifdef mess over time, and
many of the current checks are incorrect. As an example, if you build
Gtk for wayland, and exclude the X11 backend, much of the functionality
required by wayland (such as exporting menu models) will be disabled.
Solve that by introducing a backend mechanism to GtkApplication (named
GtkApplicationImpl) similar to the one in GApplication. Add backends
for Wayland, X11 and Quartz, with X11 and Wayland sharing a common
'DBus' superclass.

GtkApplicationImpl itself is essentially a bunch of vfuncs that serve as
hooks for various things that the platform-specific backends may be
interested in doing (startup, shutdown, managing windows, inhibit, etc.)
With this change, all platform specific code has been removed from
gtkapplication.c and gtkapplicationwindow.c (both of which are now free
of #ifdefs, except for a UNIX-specific use of GDesktopAppInfo in
gtkapplicationwindow.c).
Additionally, because of the movement of the property-setting code out
of GtkApplicationWindow, the _GTK_APPLICATION_ID properties (and
friends) will be set on non-GtkApplicationWindows, such as dialogs.

We don't want the maximum size to be smaller than the minimum size. Not
just because it's wrong but also because when this happens the rest of
GTK gets mighty confused and infloops resizing to min-size and
max-size in turns causing a flickering window. Well, at least if you
run X without a window manager. Or your window manager hasn't finished
starting up.
Private RHEL bug finding this issue:

Both GtkApplicationWindow and GtkHeaderBar listen for changes
of the gtk-shell-shows-app-menu setting, so they need to somehow
coordinate who is going to take action and show a fallback.
We prefer the menu button in the title over the menubar, so
let GtkApplicationWindow opt out if it finds that the header bar
has been configured to show window controls.
And deprecate the X11-specific version of it.
We call this new API _set_shadow_width() and not _set_frame_extents()
because we already have a gdk_window_get_frame_extents() with a
different meaning and different type of value.

When setting a custom titlebar that happens to be a GtkHeaderBar,
we connect to notify::title to pick up title changes on the headerbar,
but we forgot to sync the title initially. Fix that.
Win32 does not have alpha channel currently ; fix the check
for this, so trying to enable CSDs on this platform will
not "succeed" and crash the app anymore.
Partially fixes gtk3-widget-factory.
Instead, use the monitor's work area.
This might have unforseen side effects that warrant a later revert, such
as:
- Apparently some WMs assume maximizing when a window is maximum screen
size.
- WMs might not shrink the window by the decorations' size when it tries
to be fullscreen.
- Applications might have buggy size request code that causes weirdly
sized windows.
Do the menubutton for app menu fallback ourselves in GtkWindow
for the csd, non-custom titlebar case. This fits better with
the way we handle other title buttons. Themes have control
over the placement of this button by placing menu in the
decoration-button-layout style property.
Rework how accels are handled on GtkApplicationWindow.
Instead of having GtkApplication fill the GtkAccelMap which is then used
by GtkApplicationWindow to create a GtkAccelGroup filled with closures
that is then associated with the window, do it directly.
GtkApplication now keeps a list of accels and their actions.
Accelerators on a GtkApplicationWindow ask GtkApplication to execute the
appropriate action.
This saves a fair bit of complexity and memory use (due to not having to
create all those closures and accelmap entries). The new approach also
supports multiple accels per action (although there is not yet a public
API for it).
This patch (and the ones before) Reviewed and ACK'd by Matthias Clasen.
Previously, GtkWindow would add the "app" action group to its own
toplevel muxer.
Change the setup so that GtkApplication creates the toplevel muxer and
adds itself to it as "app". Use this muxer as the parent muxer of any
GtkWindow associated with the application.
This saves a small amount of memory and will allow for accels to be
propagated from the application through to all of the windows.
Resize modes don't work anymore, both because nobody ever uses them and
because the frame clock changed the way things work quite a bit. So we
don't want to advertise them as a good idea.

Previously, we were showing and hiding the custom titlebar
widget in response to state changes such as maximization.
Instead, use gtk_widget_set_child_visible() and leave
show/hide to applications. This makes it possible to set
a custom titlebar and hide it, for a titlebar-less appearance.

The size of the shadow and invisible borders can (and usually
will) change between backdrop and focused windows, while the
overall window size remains unchanged. This causes the visible
window to visually 'jump'. We can avoid this by always reserving
the maximum of the focused and unfocused border sizes. The code
for positioning the input-only windows making up the invisible
border is adjusted to deal with this. We now always place the
invisible border right outside the visible content, even if the
shadow extends out much farther.

We need to subtract border_width from the size we're passing to the
children hfw functions as those are added by ourselves.
Fixes the window-border-width.ui reftest.
At least for header bars, there's often application controls
in this area, which should be included in the focus chain.
We make it so that the initial focus avoids the titlebar,
but tabbing around will eventually get there.
