disconnect_by_func() is slow, and this becomes particularly evident
when disposing a number of widgets (and their associated style
context) at once, such as when using a language binding which
uses a GC.

It seems that alternate implementations of GtkFileChooserWidget
never materialized. The split between GtkFileChooserWidget and
GtkFileChooserDefault is awkward. The immediate problem is that
it makes it difficult to document the keybinding signals. So it
makes sense to drop the abstraction and just have one thing.

The button press/release handlers did invariably return FALSE, even
though it shouldn't if a row was found on the event coordinates. Also,
use GDK_EVENT_* defines for the return values.
The minimal size if no child widget was present/shown was far too small
to have enough room for the arrow width plus border radii, so
gtk_render_frame_gap would spew warnings about the gap being out of
boundaries.

If the grab is released during button press, the button release is
just then sent to the widget below the pointer. Depending on the
widget implementation, this could already trigger actions if the
widget does not perform any kind of button state tracking. It is
safer to ungrab on button release so no extra actions are possibly
triggered, and the behavior is uniform across widgets.
But the opposite situation may also happen, that a popover is
shown/grabbed on a button press event, so it'd get the sole button
release event after being shown, so prepare for that case by making
popover ignore single button release events with no preceding button
press.

Removable USB drives or memory sticks should be powered down
when the eject button is pressed. For this, we need to call
g_drive_stop() instead of g_drive_eject(), provided the drive
can be stopped.

Add printer_compare() function for comparing printers according
to their names and locations. It is possible to search by multiple
keys separated by space or tabulator using logical conjunction.

The root window is a fairly X-centric concept, and it
really has no place in the GtkWidget API. Plus, this
is a rarely-used one-line convenience function with
poor documentation.
Instead of setting "use-header-bar" from gtk_about_dialog_new(),
override its default value by inspecting the properties at constructor()
time. This makes it work from bindings as well, since they don't use the
convenience C constructor.

GtkWindow has 4 (!) APIs for setting window icons, and we
have to try them all in the right order to find the right
icon. This commit makes it so, and keeps the icon list
manipulation inside gtkwindow.c by adding a private API
for getting a single icon at the right size.

It was only done so the background would connect visually to the popover
tail, but then it brings aliasing issues when the border is drawn over the
background. Instead, overdraw the tail, so it also fills the gap left by
the border.
If pointing_to starts falling outside of the parent scrollable allocation,
the popover will be automatically hidden, and shown back again when
pointing_to scrolls back to visibility.
If the rect a handle points to starts falling outside of the parent
scrollable allocation, the handle will be automatically hidden, and
shown again when the rectangle is visible too.
When all popovers are removed on destroy(), if a popover is nested into
(eg. with relative_to within) another popover, the removal of one can
lead to the other being removed while the hashtable is being iterated,
which would lead to undefined behavior in further iterations.
Then, use a GList to store popovers, iterating can be made more resilient
on these situations, and unless on pathological cases there's not going
to be as many of those popovers as to cause performance decreases at the
times those are iterated.
The popovers may return keyboard grabs to previous widgets, so if
called after unsetting the focus, the window may be left with a
dangling GtkWidget that would cause crash at later dispose() calls.
With only get_preferred_width and get_preferred_height implemented,
we end up calling the GtkBin height_for_width implmementation, which
knows nothing about the margins and paddings that GtkPopover needs.
As a result, a listbox added to a popover was getting cut off
at the bottom.
This property is TRUE by default, when a popover is modal, it
will automatically set a GTK+ grab on the popover, and grab
the keyboard focus into the popover.
Popovers are strange in the sense that they aren't attached to a
parent directly, they rely on the relative_to widget so the toplevel
is shared, and when they have a parent, it is the toplevel itself,
not relative_to. This also means that there are conditions where the
popover loses it's parent, so they must survive unparenting.
The previous code would be floating the last reference as soon as the
parent is gone, but it was non-obvious who'd own that reference. So
fix this situation by granting the ownership of popovers to their
relative_to widget, an extra reference may be held by the toplevel
when the popover has a parent, but the popover object will be
guaranteed to be alive as long as the parent lives.
This way, memory management of popovers is as hidden from the user
as regular widgets within containers are, users are free to call
gtk_widget_destroy() on a popover, but it'd eventually become
destructed when relative_to is.
When a popover is focused, the focus is forwarded so the first
child what would get the focus actually gets it. Also, implement
correct focus chain, so the keyboard focus stays within the popover
when navigating with keyboard.
This makes it possible to move/resize client-side decorated windows that are
otherwise obscured by a GTK+ grab somewhere else, either a popover within the
window itself or a modal dialog above the window.
This offers the same behavior, but GDK_WINDOW_TEMP windows aren't used
anymore, involving less translations from/to root coordinates, plus no
glitches in having handles snap to content as windows move.
If there is a GTK+ grab on the popover, ensure that it's removed when it's
unmapped. If no GTK+ grab was performed on the popover, this function will
do nothing.
Those functions aren't as useful anymore, hiding/showing can be
controlled by setting the widget visibility, and grabbing can be
achieved by performing a GTK+ grab.
GdkWindows are gone now from the API, the pointed_to rectangle
is from now on relative to the widget allocation. GtkTextView
and GtkEntry were updated to adapt to this change.
This is not as necessary now that bubble windows are popovers, if
a modal behavior is wanted on popover contents, a GTK+ grab on the
popover widget will suffice.
Popovers are transient floating widgets that are confined to the
window space. These have their own GdkWindow that is set on top
of the regular window contents, so they can be used for popup menu
alike UIs with custom popup/popdown/grabs behavior.
