This code is called from handlers connected to signals of a
MetaWindow. It cannot happen that the window will end up NULL
in these, so exchange with a g_assert() as we in fact expect
it to be non-NULL.

We cannot use a function with the same signature for signals with different
arguments, if we want to rely on the user data parameter. Separate into
two signal handlers calling the same function inside.

The two dialog creation virtual functions returned by these functions have to
be unreferenced by the caller (and are actually unreferenced in other places in
the code).

This gives greater control to the callers on the place where a grab is being
activated, this may make a difference in the handling of crossing events
triggered through it, e.g. by having callers rely on having already obtained
a ClutterGrab prior to handling the resulting effects.
The "input only" grab has also been turned inactive by default, in order to
to have the ClutterGrab pointer available for checks at the MetaWaylandEventHandler
focus changing methods triggered through grab activation.

If the titlebar of a window has been moved above the screen by a user
via an unconstrained move, then any constrained user resize following
this move will cause the window to jump below the top of the screen or
cause other glitchy behavior.
This commit removes the constraint that the titlebar of a window must be
below the top of the screen for any resize that is both (1) triggered by
a user and (2) is a resize that affects only the left, right, or bottom
edges of the window. This allows users to move a window partially above
the screen and then resize the window to be wider or resize the bottom
edge of the window to make it taller or shorter.

This unbreaks building here. The compilation error was due to
MetaX11Display having an incorrect typedef in a now preprocessed out
part, which will be fixed in a later commit.

Allows gnome-shell or other compositors to detect which features

Moving a window is a compositor action and happens immediately. Waiting
here is pointless. Make sure instead that the action happens immediately
by asserting the position.

wait and wait_configure after a single resize is useless and a race.
Resize is a client side action which doesn't result in a configure and a
wait doesn't sync for a resize as well.
Sometimes the resize is paired with another action, such as maximize,
fullscreen or show. In those cases a configure will be generated and a
previous resize is accounted for.

Commit e775052429 changed the code such that resetting the actor is done
when a surface role is assigned. The dnd surface assigned vfunc doesn't
chain up which means the code to reset the actor is never hit and the
dnd surface never shows up.

In these checks, it's an important detail to preserve subpixel information
in order to correctly determine whether the coordinates are inside or
outside a view.
Otherwise, small enough motion towards the left/top might get rounded
to 0, be seen as "inside the view", and the pointer coordinates be allowed
to escape the viewport constraints.
This was figured out by Pascal Nowack before me, with a difference of
minutes. Credit where credit is due.

In meta_seat_impl_remove_virtual_input_device(), the 'device'
variable is first removed from MetaSeatImpl, then a "device
removed" event is generated with it.
The problem here is that, if this is the last reference of
'device', the removal from MetaSeatImpl will destroy it. Then
the freed variable will be used to create the "device removed"
event, which is a use-after-free situation.
Fix that by owning an extra ref to 'device' as long as the
function is executing. Do this by declaring a g_autoptr
variable with the extra ref. This g_autoptr variable is cleaned
up by the end of the function, which achieves the desired effect.

Right now the unmapped signal doesn't always fire which means we didn't
see a surface that's being unmapped in these code paths before. In
particular the resource, window and role can be gone. Handle those
cases.
