Now GtkWindow takes some measures when setting toplevelness:
- When a window becomes toplevel after being embedded it saves
the visibility state and reshow's itself so that the window
re-realizes and presents itself again automatically
- When emitting hierarchy-changed, synthetically mark the toplevel
as not anchored, this allows the hierarchy changed propagation to
recurse properly.
GtkWidget also takes care to unset the parent window *after* unparenting
the widget and after emitting the heirarhcy changed that leaves a NULL
toplevel.
That means there are now 2 cycles of "hierarchy-changed" when removing
an embedded toplevel from a parent, first one that makes the new toplevel
a NULL one (since the toplevel flag is not yet restored), the second cycle
makes the removed window toplevel again when setting the parent window
to NULL.
GtkFileChooserDefault watches the toplevel and montitors "set-focus"
signal on it... however the connection needs to be remade when the
GtkFileChooserDialog is in an embedded toplevel.
Measure's taken: GtkWindow propagates hierarchy changes when
_gtk_window_set_is_toplevel() is called, gtk_widget_unparent()
unsets the widget's parent window earlier in the function so that
the possible hierarchy change is still able to properly access the hierarchy.
GtkFileChooserDefault checks if the "new" toplevel is indeed
gtk_widget_is_toplevel() but not the old one, GtkRange has been
updated to use gtk_widget_is_toplevel() inside it's hierarhcy_changed
vfunc, other classes already do this properly.
This patch makes gtk_widget_set_parent_window() undo the toplevelness
of a GtkWindow, GtkWindow then realizes itself as a normal child widget
and behaves like a normal GtkBin by checking gtk_widget_is_toplevel() in
several places (show/hide/map/unmap/draw/size_allocate/check_resize/configure_event).
GtkWindow was only releasing the application in finalize, causing
problems for language bindings. Now we release it already in destroy
(and then again in finalize for good measure).

The functions to set frames on windows stopped being interesting
when the linux framebuffer port was dropped, many years ago.
Similar functionality may come back with client-side decorations
in the future.
Requires fixes to GtkContainer and GtkWindow to unmap their
children, rather than just withdrawing or hiding the container
window.
Requires fix to GtkHandleBox to chain up to GtkContainer unmap.
Historically we avoided these unmaps for efficiency reasons,
but these days it's a bigger problem that there's no way
for child widgets to know that one of their ancestors has
become unmapped.
In the process of removing all sealed members from headers.
At the same time, add a gtkwindowprivate.h header and move
all internal functions from gtkwindow.h there.
- add slots for damage-event, move-focus and keynav-failed
- reorder signals a bit so related stuff is grouped together
- some indentation fixes in the GtkWidgetClass
- remove the move-focus compat hack from GtkTextView
- turn the move-focus compat hack in GtkWindow into properly
implementing GtkWidget::move-focus()
The gtkprivate.h header contains GtkWidget-specific private symbols that
are not useful except in a handful of cases. Basically everything
includes gtkprivate.h for the GTK_PARAM_* macros.

Safe space in the private struct, always set the cursor when we
update visibility, since the cursor depends on resizability conditions
too. And don't set the shape needlessly.
This was caused by get_drag_edge() returning -1 to mean 'no drag',
but callers didn't really pay attention. Change get_drag_edge()
to return a boolean instead.
If you set a geometry widget via gtk_window_set_geometry_hints() it
becomes very hard to compute appropriate toplevel sizes in pixels
to make the window a particular size. Synthesizing strings and passing
them to gtk_window_parse_geometry() is possible, but to avoid
avoid such ugliness, add functions:
gtk_window_set_default_geometry()
gtk_window_resize_to_geometry()
That act like gtk_window_set_default_size() and
gtk_window_resize() but are in terms of the resize increments of the
geometry widget.

gtk_window_parse_geometry() gets the size of the window in order
to interpret the position of the window; calling it before, say,
calling gtk_widget_show_all() on a window is a subtle trap, so
add a warning in the case we can easily detect.
https://bugzilla.gnome.org/show_bug.cgi?id=631794
The geometry widget feature of gtk_window_set_geometry_hints() has
never really worked right because the calculation that GTK+ did to
compute the base size of the window only worked when the geometry
widget had a larger minimum size than anything else in the window.
Setup:
* Move the GtkSizeGroup private functions to a new private header
gtksizegroup-private.h
* Add the possibilty to pass flags to _gtk_size_group_queue_resize(),
with the flag GTK_QUEUE_RESIZE_INVALIDATE_ONLY to suppress adding
the widget's toplevel to the resize queue.
* _gtk_container_resize_invalidate() is added to implement that feature
* _gtk_widget_override_size_request()/_gtk_widget_restore_size_request()
allow temporarily forcing a large minimum size on the geometry
widget without creating resize loops.
GtkWindow:
* Compute the extra width/height around the geometry widget
correctly; print a warning if the computation fails.
* Always make the minimum size at least the natural minimum
size of the toplevel; GTK+ now fails badly with underallocation.
* Always set the base size hint; we were failing to set it
properly when the specified minimum size was overriden, but
it's harmless to always set it.
Tests:
* New test 'testgeometry' that replaces the 'gridded geometry' test
from testgtk. The new test is roughly similar but creates a bunch
of windows showing different possibilities.
* The testgtk test is removed. No need to have both.
