63bb834b2e popover: Accept NULL relative_to widgets
And document the fact that the popover will get destroyed if
a NULL relative-to is given on a parented popover, if no extra
references are kept.

For gtk_popover_new*(), a NULL relative-to will leave the widget
as a floating object, to be sunk by a later call to
gtk_widget_set_relative_to().

72e2094472 Drop with_separators from gtk_popover_bind_model
The with_separators argument does not really make sense
for popovers, it was just copied from the menu implementation.
Drop it now, before it becomes part of the public API.

14ba1280ce Improve popover positioning
Improve the algorithm to determing popover placement:
If it fits in the preferred direction or its opposite,
do that, otherwise use the direction that causes the least
of the popover to be cut off.

2fea2d4dbd Populate popovers from menu models
This adds a new function, gtk_popover_new_from_model, which creates
a popover and populates it with suitable content according to the
menu model. The current implementation uses GtkModelButton for the
individual items, and a GtkStack for submenus.

98a67d9697 popover: propagate (insensitive|backdrop) flags from relative-to widget
Popovers aren't direct children of the widget they point to, but yet
they act as children of it, so do the same with state propagation,
so the flags that propagate across the hierarchy reach popovers too.

63bed5d040 popover: Listen on grab_notify from the relative-to widget
Anytime ::grab-notify comes across, the popover visibility and GTK+
grab ownership are checked, so the popover is hidden when it loses
the GTK+ by any reason.

2d9c09d6c0 popover: Add private _gtk_popover_set_apply_shape() call
Popovers no longer sets a shape, unless this function is called. This
function exists so widgets that are potentially placed on top of other
native windows can get a popover that's nicely shaped, even if it has
no border shadow around.

709fb26587 popover: Improve minimal size allocation
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.

7b4ef99320 popover: Hide/ungrab on button release
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.

074e17e100 popover: Don't overdraw background
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.

ea0a1e31a7 Implement wfh functions
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.

1d495cbafd popover: Add a "modal" boolean property to GtkPopover

31042fe95f popover: Fix memory management of popovers
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.

342c23da23 popover: Implement keyboard focus behavior
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.
