Currently there is no way to alter the offset of the popup when positioning
with GdkPopupLayout. This makes using the popup difficult for scenarios
like completion windows where you may need to offset the window by a given
amount for aligning text.
gtk_popover_set_offset() allows setting these values and are analagous to
the function of the same name for GdkPopupLayout.
Add private gtk_tooltip_maybe_allocate() function
and use it from GtkWindow and GtkPopover.
This will let us stop using the ::size-allocate signal,
without having to redo all the tooltip management first.
That will happen later.
When we find out that we've been flipped, set
final_position and final_rect before allocating
the popover. This prevents 'smashed-in beak' disease.
Fixes: #2671
If the popover fails to be shown, it would internally undo visible
and mapped state. If we just proceed as normal, the widget enters
in inconsistent state, and a grab remains issued on the invisible
widget, preventing further input from the input device.
These popovers handle clicks outside the widget, and expect input
to be routed through it when it is shown. This pretty much matches
the characteristics of GTK grabs, and setting one up will ensure
the cancellation of event controllers that were active at the time
of showing the popover.

Unfortunately, this involves copying a bunch of
code from gtkwindow.c. The only difference here
is that we add a private method to turn this off,
which will be used by GtkPopoverMenu to implement
its own auto mnemonics.
The shortcut controllers are limited to same-native,
so we need to duplicate the Tab and arrow key bindings
for focus handling, as well as the Enter bindings for
activation.
This ensures the popover will follow the new position parameters. This is
necessary for popovers like the text magnifier that can be repositioned
while visible.

There is no shape combining going on anymore, so
call this just gdk_surface_set_input_region, and
remove the offset arguments too. All callers pass
0 anyway.
Update all callers and implementations.
It is enough to just set the parent (and make the parent
call gtk_native_check_resize in size_allocate).
This commit removes the relative_to argument to the
constructors of GtkPopover and GtkPopoverMenu, and
updates all callers.
FIXME: Is this necessary?
Could the surfaces just clamp to 1x1 themselves?
We recently declared that surfaces can decide on whatever size they want
so natives need to inspect the size they requested anyway.
Instead of relying on gdk's antiquated crossing events,
create a new GtkCrossingData struct that contains the
actual widgets, and a new event controller vfunc that
expects this struct. This also saves us from making sense
of X's crossing modes and details, and makes for a
generally simpler api.
The ::focus-in and ::focus-out signals of GtkEventControllerKey
have been replaced by a single ::focus-change signal that
takes GtkCrossingData as an argument. All callers have
been updated.
