Since update_windows list is a static variable in GdkWindow.c which
contains pointers to windows which needs to be updated, it can happen
that it contains a pointer to a window even after quit from a gtk_main().
If another gtk_main() is called in the same process it tries to process
windows in the list which leads to a crash.
Correct reference count handling of added windows prevents such applications
from crash.

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.

This could happen if data was requested from a separate screen now that
multi-screen is no longer supported.
Ideally, we'd want to support copying to other screens, but that
requires solving in GDK as that's X-specific so cannot be well
abstracted by GDK (without the reintroduction of multiple screens).

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.
If we don't have a window icon, we hide the titlebar_icon,
we still add it, so we can't simply go by the number of
children when deciding whether to show the separator or
now. Instead, update the separator visibility as we create
the various buttons.
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.

Turn this into a GtkApplication with an app menu.
Allow to override the gtk-shell-shows-app-menu setting
and the decoration-button-layout style property.
This is one of the few cases where it makes some sense to blur
the line between and empty string and NULL: without this, it is
hard to reset the subtitle e.g. from a builder file. And we
have the has-subtitle property now to enforce subtitle size
allocation independently.
Only fill the location entry with the file name of the tree view's
selected file when the selection was done by the user.
When the file chooser's action is GTK_FILE_CHOOSER_ACTION_OPEN, it
selects the first file in the tree view once loading has finished. For
this case we don't want it to insert the file name in the location
entry, as it hinders efficient navigation using the location entry. To
achieve this, use a priv flag to keep track of whether the
selection-changed signal was caused by the file chooser itself.

Now that the nice titlebar example is in gtk3-demo, we can
use testtitlebar as an actual testbed for headerbar stuff.
This immediately reveals size allocation issues when titlebar
widgets change size.
It is a fairly common case to just want a title, and not
reserve extra space for a subtitle. This is much easier
to get right by setting a boolean property than by
constructing a custom title widget.
